Google Chrome
–
Google Chrome is a freeware web browser developed by Google. It was first released in 2008, for Microsoft Windows, and was ported to Linux, macOS, iOS. Google Chrome is also the component of Chrome OS, where it serves as a platform for running web apps. Google releases the majority of Chromes source code as the Chromium open-source project, a notable component that is not open-source is the built-in Adobe Flash Player. Chrome used the WebKit layout engine until version 27, as of version 28, all Chrome ports except the iOS port use Blink, a fork of the WebKit engine. As of February 2017, StatCounter estimates that Google Chrome has a 62% worldwide usage share of web browsers as a desktop browser and it also has 52% market share across all platforms combined, because it is also the most popular browser for smartphones. Its success has led to Google expanding the Chrome brand name on other products such as Chromecast, Chromebook, Chromebit, Chromebox. Google CEO Eric Schmidt opposed the development of an independent web browser for six years and he stated that at the time, Google was a small company, and he did not want to go through bruising browser wars. Rumors of Google building a web browser first appeared in September 2004, online journals and U. S. newspapers stated at the time that Google was hiring former Microsoft web developers among others. It also came shortly after the final 1.0 release of Mozilla Firefox, the release announcement was originally scheduled for September 3,2008, and a comic by Scott McCloud was to be sent to journalists and bloggers explaining the features within the new browser. Google subsequently made the comic available on Google Books and mentioned it on their blog along with an explanation for the early release. The browser was first publicly released on September 2,2008 for Windows XP and later, with 43 supported languages, officially a beta version and this passage was inherited from the general Google terms of service. Google responded to this criticism immediately by stating that the language used was borrowed from other products, Chrome quickly gained about 1% usage share. After the initial surge, usage share dropped until it hit a low of 0. 69% in October 2008 and it then started rising again and by December 2008, Chrome again passed the 1% threshold. In early January 2009, CNET reported that Google planned to release versions of Chrome for OS X, in December 2009, Google released beta versions of Chrome for OS X and Linux. Google Chrome 5.0, announced on May 25,2010, was the first stable release to all three platforms. Chrome was one of the twelve browsers offered to European Economic Area users of Microsoft Windows in 2010, the V8 JavaScript virtual machine was considered a sufficiently important project to be split off and handled by a separate team in Denmark coordinated by Lars Bak at Aarhus. Chrome initially used the WebKit rendering engine to display web pages, in 2013, they forked the WebCore component to create their own layout engine Blink

Software developer
–
A software developer is a person concerned with facets of the software development process, including the research, design, programming, and testing of computer software. Other job titles which are used with similar meanings are programmer, software analyst. According to developer Eric Sink, the differences between system design, software development, and programming are more apparent, even more so that developers become systems architects, those who design the multi-leveled architecture or component interactions of a large software system. In a large company, there may be employees whose sole responsibility consists of one of the phases above. In smaller development environments, a few people or even an individual might handle the complete process. The word software was coined as a prank as early as 1953, before this time, computers were programmed either by customers, or the few commercial computer vendors of the time, such as UNIVAC and IBM. The first company founded to provide products and services was Computer Usage Company in 1955. The software industry expanded in the early 1960s, almost immediately after computers were first sold in mass-produced quantities, universities, government, and business customers created a demand for software. Many of these programs were written in-house by full-time staff programmers, some were distributed freely between users of a particular machine for no charge. Others were done on a basis, and other firms such as Computer Sciences Corporation started to grow. The computer/hardware makers started bundling operating systems, systems software and programming environments with their machines, new software was built for microcomputers, so other manufacturers including IBM, followed DECs example quickly, resulting in the IBM AS/400 amongst others. The industry expanded greatly with the rise of the computer in the mid-1970s. In the following years, it created a growing market for games, applications. DOS, Microsofts first operating system product, was the dominant operating system at the time, by 2014 the role of cloud developer had been defined, in this context, one definition of a developer in general was published, Developers make software for the world to use. The job of a developer is to crank out code -- fresh code for new products, code fixes for maintenance, code for business logic, bus factor Software Developer description from the US Department of Labor

Google
–
Google is an American multinational technology company specializing in Internet-related services and products. These include online advertising technologies, search, cloud computing, software, Google was founded in 1996 by Larry Page and Sergey Brin while they were Ph. D. students at Stanford University, in California. Together, they own about 14 percent of its shares, and they incorporated Google as a privately held company on September 4,1998. An initial public offering took place on August 19,2004, in August 2015, Google announced plans to reorganize its various interests as a conglomerate called Alphabet Inc. Google, Alphabets leading subsidiary, will continue to be the company for Alphabets Internet interests. Upon completion of the restructure, Sundar Pichai became CEO of Google, replacing Larry Page, rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Googles core search engine. The company leads the development of the Android mobile operating system, the Google Chrome web browser, and Chrome OS, the new hardware chief, Rick Osterloh, stated, a lot of the innovation that we want to do now ends up requiring controlling the end-to-end user experience. Google has also experimented with becoming an Internet carrier, alexa, a company that monitors commercial web traffic, lists Google. com as the most visited website in the world. Several other Google services also figure in the top 100 most visited websites, including YouTube, Googles mission statement, from the outset, was to organize the worlds information and make it universally accessible and useful, and its unofficial slogan was Dont be evil. In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase Do the right thing, Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California. They called this new technology PageRank, it determined a websites relevance by the number of pages, and the importance of those pages, Page and Brin originally nicknamed their new search engine BackRub, because the system checked backlinks to estimate the importance of a site. Originally, Google ran under Stanford Universitys website, with the domains google. stanford. edu, the domain name for Google was registered on September 15,1997, and the company was incorporated on September 4,1998. It was based in the garage of a friend in Menlo Park, craig Silverstein, a fellow PhD student at Stanford, was hired as the first employee. The first funding for Google was an August 1998 contribution of $100,000 from Andy Bechtolsheim, co-founder of Sun Microsystems, given before Google was incorporated. At least three other investors invested in 1998, Amazon. com founder Jeff Bezos, Stanford University computer science professor David Cheriton. Author Ken Auletta claims that each invested $250,000, early in 1999, Brin and Page decided they wanted to sell Google to Excite. They went to Excite CEO George Bell and offered to sell it to him for $1 million, vinod Khosla, one of Excites venture capitalists, talked the duo down to $750,000, but Bell still rejected it. Googles initial public offering took place five years later, on August 19,2004, at that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for 20 years, until the year 2024

Software release life cycle
–
Usage of the alpha/beta test terminology originated at IBM. As long ago as the 1950s, IBM used similar terminology for their hardware development, a test was the verification of a new product before public announcement. B test was the verification before releasing the product to be manufactured, C test was the final test before general availability of the product. Martin Belsky, a manager on some of IBMs earlier software projects claimed to have invented the terminology, IBM dropped the alpha/beta terminology during the 1960s, but by then it had received fairly wide notice. The usage of beta test to refer to testing done by customers was not done in IBM, rather, IBM used the term field test. Pre-alpha refers to all activities performed during the project before formal testing. These activities can include requirements analysis, software design, software development, in typical open source development, there are several types of pre-alpha versions. Milestone versions include specific sets of functions and are released as soon as the functionality is complete, the alpha phase of the release life cycle is the first phase to begin software testing. In this phase, developers generally test the software using white-box techniques, additional validation is then performed using black-box or gray-box techniques, by another testing team. Moving to black-box testing inside the organization is known as alpha release, alpha software can be unstable and could cause crashes or data loss. Alpha software may not contain all of the features that are planned for the final version, in general, external availability of alpha software is uncommon in proprietary software, while open source software often has publicly available alpha versions. The alpha phase usually ends with a freeze, indicating that no more features will be added to the software. At this time, the software is said to be feature complete, Beta, named after the second letter of the Greek alphabet, is the software development phase following alpha. Software in the stage is also known as betaware. Beta phase generally begins when the software is complete but likely to contain a number of known or unknown bugs. Software in the phase will generally have many more bugs in it than completed software, as well as speed/performance issues. The focus of beta testing is reducing impacts to users, often incorporating usability testing, the process of delivering a beta version to the users is called beta release and this is typically the first time that the software is available outside of the organization that developed it. Beta version software is useful for demonstrations and previews within an organization

C++
–
C++ is a general-purpose programming language. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation and it was designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency and flexibility of use as its design highlights. C++ is a language, with implementations of it available on many platforms and provided by various organizations, including the Free Software Foundation, LLVM, Microsoft, Intel. C++ is standardized by the International Organization for Standardization, with the latest standard version ratified and published by ISO in December 2014 as ISO/IEC14882,2014. The C++ programming language was standardized in 1998 as ISO/IEC14882,1998. The current C++14 standard supersedes these and C++11, with new features, the C++17 standard is due in 2017, with the draft largely implemented by some compilers already, and C++20 is the next planned standard thereafter. Many other programming languages have influenced by C++, including C#, D, Java. In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on C with Classes, the motivation for creating a new language originated from Stroustrups experience in programming for his Ph. D. thesis. When Stroustrup started working in AT&T Bell Labs, he had the problem of analyzing the UNIX kernel with respect to distributed computing, remembering his Ph. D. experience, Stroustrup set out to enhance the C language with Simula-like features. C was chosen because it was general-purpose, fast, portable, as well as C and Simulas influences, other languages also influenced C++, including ALGOL68, Ada, CLU and ML. Initially, Stroustrups C with Classes added features to the C compiler, Cpre, including classes, derived classes, strong typing, inlining, furthermore, it included the development of a standalone compiler for C++, Cfront. In 1985, the first edition of The C++ Programming Language was released, the first commercial implementation of C++ was released in October of the same year. In 1989, C++2.0 was released, followed by the second edition of The C++ Programming Language in 1991. New features in 2.0 included multiple inheritance, abstract classes, static functions, const member functions. In 1990, The Annotated C++ Reference Manual was published and this work became the basis for the future standard. Later feature additions included templates, exceptions, namespaces, new casts, after a minor C++14 update released in December 2014, various new additions are planned for 2017 and 2020. According to Stroustrup, the name signifies the nature of the changes from C. This name is credited to Rick Mascitti and was first used in December 1983, when Mascitti was questioned informally in 1992 about the naming, he indicated that it was given in a tongue-in-cheek spirit

Operating system
–
An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require a system to function. Operating systems are found on many devices that contain a computer – from cellular phones, the dominant desktop operating system is Microsoft Windows with a market share of around 83. 3%. MacOS by Apple Inc. is in place, and the varieties of Linux is in third position. Linux distributions are dominant in the server and supercomputing sectors, other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications. A single-tasking system can run one program at a time. Multi-tasking may be characterized in preemptive and co-operative types, in preemptive multitasking, the operating system slices the CPU time and dedicates a slot to each of the programs. Unix-like operating systems, e. g. Solaris, Linux, cooperative multitasking is achieved by relying on each process to provide time to the other processes in a defined manner. 16-bit versions of Microsoft Windows used cooperative multi-tasking, 32-bit versions of both Windows NT and Win9x, used preemptive multi-tasking. Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem, a distributed operating system manages a group of distinct computers and makes them appear to be a single computer. The development of networked computers that could be linked and communicate with each other gave rise to distributed computing, distributed computations are carried out on more than one machine. When computers in a work in cooperation, they form a distributed system. The technique is used both in virtualization and cloud computing management, and is common in large server warehouses, embedded operating systems are designed to be used in embedded computer systems. They are designed to operate on small machines like PDAs with less autonomy and they are able to operate with a limited number of resources. They are very compact and extremely efficient by design, Windows CE and Minix 3 are some examples of embedded operating systems. A real-time operating system is a system that guarantees to process events or data by a specific moment in time. A real-time operating system may be single- or multi-tasking, but when multitasking, early computers were built to perform a series of single tasks, like a calculator. Basic operating system features were developed in the 1950s, such as resident monitor functions that could run different programs in succession to speed up processing

Microsoft Windows
–
Microsoft Windows is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture. Active Windows families include Windows NT, Windows Embedded and Windows Phone, defunct Windows families include Windows 9x, Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile. Microsoft introduced an operating environment named Windows on November 20,1985, Microsoft Windows came to dominate the worlds personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984. Apple came to see Windows as an encroachment on their innovation in GUI development as implemented on products such as the Lisa. On PCs, Windows is still the most popular operating system, however, in 2014, Microsoft admitted losing the majority of the overall operating system market to Android, because of the massive growth in sales of Android smartphones. In 2014, the number of Windows devices sold was less than 25% that of Android devices sold and this comparison however may not be fully relevant, as the two operating systems traditionally target different platforms. As of September 2016, the most recent version of Windows for PCs, tablets, smartphones, the most recent versions for server computers is Windows Server 2016. A specialized version of Windows runs on the Xbox One game console, Microsoft, the developer of Windows, has registered several trademarks each of which denote a family of Windows operating systems that target a specific sector of the computing industry. It now consists of three operating system subfamilies that are released almost at the time and share the same kernel. Windows, The operating system for personal computers, tablets. The latest version is Windows 10, the main competitor of this family is macOS by Apple Inc. for personal computers and Android for mobile devices. Windows Server, The operating system for server computers, the latest version is Windows Server 2016. Unlike its clients sibling, it has adopted a strong naming scheme, the main competitor of this family is Linux. Windows PE, A lightweight version of its Windows sibling meant to operate as an operating system, used for installing Windows on bare-metal computers. The latest version is Windows PE10.0.10586.0, Windows Embedded, Initially, Microsoft developed Windows CE as a general-purpose operating system for every device that was too resource-limited to be called a full-fledged computer. The following Windows families are no longer being developed, Windows 9x, Microsoft now caters to the consumers market with Windows NT. Windows Mobile, The predecessor to Windows Phone, it was a mobile operating system

MacOS
–
Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS after Microsoft Windows. Launched in 2001 as Mac OS X, the series is the latest in the family of Macintosh operating systems, Mac OS X succeeded classic Mac OS, which was introduced in 1984, and the final release of which was Mac OS9 in 1999. An initial, early version of the system, Mac OS X Server 1.0, was released in 1999, the first desktop version, Mac OS X10.0, followed in March 2001. In 2012, Apple rebranded Mac OS X to OS X. Releases were code named after big cats from the release up until OS X10.8 Mountain Lion. Beginning in 2013 with OS X10.9 Mavericks, releases have been named after landmarks in California, in 2016, Apple rebranded OS X to macOS, adopting the nomenclature that it uses for their other operating systems, iOS, watchOS, and tvOS. The latest version of macOS is macOS10.12 Sierra, macOS is based on technologies developed at NeXT between 1985 and 1997, when Apple acquired the company. The X in Mac OS X and OS X is pronounced ten, macOS shares its Unix-based core, named Darwin, and many of its frameworks with iOS, tvOS and watchOS. A heavily modified version of Mac OS X10.4 Tiger was used for the first-generation Apple TV, Apple also used to have a separate line of releases of Mac OS X designed for servers. Beginning with Mac OS X10.7 Lion, the functions were made available as a separate package on the Mac App Store. Releases of Mac OS X from 1999 to 2005 can run only on the PowerPC-based Macs from the time period, Mac OS X10.5 Leopard was released as a Universal binary, meaning the installer disc supported both Intel and PowerPC processors. In 2009, Apple released Mac OS X10.6 Snow Leopard, in 2011, Apple released Mac OS X10.7 Lion, which no longer supported 32-bit Intel processors and also did not include Rosetta. All versions of the system released since then run exclusively on 64-bit Intel CPUs, the heritage of what would become macOS had originated at NeXT, a company founded by Steve Jobs following his departure from Apple in 1985. There, the Unix-like NeXTSTEP operating system was developed, and then launched in 1989 and its graphical user interface was built on top of an object-oriented GUI toolkit using the Objective-C programming language. This led Apple to purchase NeXT in 1996, allowing NeXTSTEP, then called OPENSTEP, previous Macintosh operating systems were named using Arabic numerals, e. g. Mac OS8 and Mac OS9. The letter X in Mac OS Xs name refers to the number 10 and it is therefore correctly pronounced ten /ˈtɛn/ in this context. However, a common mispronunciation is X /ˈɛks/, consumer releases of Mac OS X included more backward compatibility. Mac OS applications could be rewritten to run natively via the Carbon API, the consumer version of Mac OS X was launched in 2001 with Mac OS X10.0. Reviews were variable, with praise for its sophisticated, glossy Aqua interface

Linux
–
Linux is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17,1991 by Linus Torvalds, the Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. Linux was originally developed for computers based on the Intel x86 architecture. Because of the dominance of Android on smartphones, Linux has the largest installed base of all operating systems. Linux is also the operating system on servers and other big iron systems such as mainframe computers. It is used by around 2. 3% of desktop computers, the Chromebook, which runs on Chrome OS, dominates the US K–12 education market and represents nearly 20% of the sub-$300 notebook sales in the US. Linux also runs on embedded systems – devices whose operating system is built into the firmware and is highly tailored to the system. This includes TiVo and similar DVR devices, network routers, facility automation controls, televisions, many smartphones and tablet computers run Android and other Linux derivatives. The development of Linux is one of the most prominent examples of free, the underlying source code may be used, modified and distributed—commercially or non-commercially—by anyone under the terms of its respective licenses, such as the GNU General Public License. Typically, Linux is packaged in a known as a Linux distribution for both desktop and server use. Distributions intended to run on servers may omit all graphical environments from the standard install, because Linux is freely redistributable, anyone may create a distribution for any intended use. The Unix operating system was conceived and implemented in 1969 at AT&Ts Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, first released in 1971, Unix was written entirely in assembly language, as was common practice at the time. Later, in a key pioneering approach in 1973, it was rewritten in the C programming language by Dennis Ritchie, the availability of a high-level language implementation of Unix made its porting to different computer platforms easier. Due to an earlier antitrust case forbidding it from entering the computer business, as a result, Unix grew quickly and became widely adopted by academic institutions and businesses. In 1984, AT&T divested itself of Bell Labs, freed of the legal obligation requiring free licensing, the GNU Project, started in 1983 by Richard Stallman, has the goal of creating a complete Unix-compatible software system composed entirely of free software. Later, in 1985, Stallman started the Free Software Foundation, by the early 1990s, many of the programs required in an operating system were completed, although low-level elements such as device drivers, daemons, and the kernel were stalled and incomplete. Linus Torvalds has stated that if the GNU kernel had been available at the time, although not released until 1992 due to legal complications, development of 386BSD, from which NetBSD, OpenBSD and FreeBSD descended, predated that of Linux. Torvalds has also stated that if 386BSD had been available at the time, although the complete source code of MINIX was freely available, the licensing terms prevented it from being free software until the licensing changed in April 2000

Android (operating system)
–
Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. In addition to devices, Google has further developed Android TV for televisions, Android Auto for cars. Variants of Android are also used on notebooks, game consoles, digital cameras, beginning with the first commercial Android device in September 2008, the operating system has gone through multiple major releases, with the current version being 7.0 Nougat, released in August 2016. Android applications can be downloaded from the Google Play store, which features over 2.7 million apps as of February 2017, Android has been the best-selling OS on tablets since 2013, and runs on the vast majority of smartphones. In September 2015, Android had 1.4 billion monthly active users, Android is popular with technology companies that require a ready-made, low-cost and customizable operating system for high-tech devices. The success of Android has made it a target for patent, Android Inc. was founded in Palo Alto, California in October 2003 by Andy Rubin, Rich Miner, Nick Sears, and Chris White. Rubin described the Android project as tremendous potential in developing smarter mobile devices that are aware of its owners location. The early intentions of the company were to develop an operating system for digital cameras. Despite the past accomplishments of the founders and early employees, Android Inc. operated secretly and that same year, Rubin ran out of money. Steve Perlman, a friend of Rubin, brought him $10,000 in cash in an envelope. In July 2005, Google acquired Android Inc. for at least $50 million and its key employees, including Rubin, Miner and White, joined Google as part of the acquisition. Not much was known about Android at the time, with Rubin having only stated that they were making software for mobile phones, at Google, the team led by Rubin developed a mobile device platform powered by the Linux kernel. Google marketed the platform to handset makers and carriers on the promise of providing a flexible, upgradeable system, Google had lined up a series of hardware components and software partners and signaled to carriers that it was open to various degrees of cooperation. Speculation about Googles intention to enter the communications market continued to build through December 2006. In September 2007, InformationWeek covered an Evalueserve study reporting that Google had filed several patent applications in the area of mobile telephony, the first commercially available smartphone running Android was the HTC Dream, also known as T-Mobile G1, announced on September 23,2008. Since 2008, Android has seen numerous updates which have improved the operating system, adding new features. Each major release is named in order after a dessert or sugary treat, with the first few Android versions being called Cupcake, Donut, Eclair. In 2010, Google launched its Nexus series of devices, a lineup in which Google partnered with different device manufacturers to produce new devices and introduce new Android versions

Megabyte
–
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB, but sometimes MByte is used, the unit prefix mega is a multiplier of 1000000 in the International System of Units. Therefore, one megabyte is one million bytes of information and this definition has been incorporated into the International System of Quantities. However, in the computer and information fields, several other definitions are used that arose for historical reasons of convenience. A common usage has been to one megabyte as 1048576bytes. However, most standards bodies have deprecated this usage in favor of a set of binary prefixes, less common is a convention that used the megabyte to mean 1000×1024 bytes. The megabyte is commonly used to measure either 10002 bytes or 10242 bytes, the interpretation of using base 1024 originated as a compromise technical jargon for the byte multiples that needed to be expressed by the powers of 2 but lacked a convenient name. As 1024 approximates 1000, roughly corresponding to the SI prefix kilo-, in 1998 the International Electrotechnical Commission proposed standards for binary prefixes requiring the use of megabyte to strictly denote 10002 bytes and mebibyte to denote 10242 bytes. By the end of 2009, the IEC Standard had been adopted by the IEEE, EU, ISO, the Mac OS X10.6 file manager is a notable example of this usage in software. Since Snow Leopard, file sizes are reported in decimal units, base 21 MB =1048576 bytes is the definition used by Microsoft Windows in reference to computer memory, such as RAM. This definition is synonymous with the binary prefix mebibyte. Mixed 1 MB =1024000 bytes is the used to describe the formatted capacity of the 1.44 MB3. 5inch HD floppy disk. Semiconductor memory doubles in size for each address lane added to an integrated circuit package, the capacity of a disk drive is the product of the sector size, number of sectors per track, number of tracks per side, and the number of disk platters in the drive. Changes in any of these factors would not usually double the size, sector sizes were set as powers of two for convenience in processing. It was an extension to give the capacity of a disk drive in multiples of the sector size, giving a mix of decimal. Depending on compression methods and file format, a megabyte of data can roughly be, a 4 megapixel JPEG image with normal compression. Approximately 1 minute of 128 kbit/s MP3 compressed music,6 seconds of uncompressed CD audio. A typical English book volume in plain text format, the human genome consists of DNA representing 800 MB of data

Virtual globe
–
A virtual globe is a three-dimensional software model or representation of the Earth or another world. A virtual globe provides the user with the ability to move around in the virtual environment by changing the viewing angle. Compared to a globe, virtual globes have the additional capability of representing many different views on the surface of the Earth. These views may be of geographical features, man-made features such as roads and buildings, on November 20,1997, Microsoft released an offline virtual globe in the form of Encarta Virtual Globe 98, followed by Cosmis 3D World Atlas in 1999. The first widely publicized online virtual globes were NASA World Wind, NOAA released its virtual globe, Science On A Sphere Explorer, in September 2015. Virtual globes may be used for study or navigation and their design varies considerably according to their purpose and those wishing to portray a visually accurate representation of the Earth often use satellite image servers and are capable not only of rotation but also zooming and sometimes horizon tilting. Very often such virtual globes aim to provide as true a representation of the World as is possible with worldwide coverage up to a detailed level. Another type of virtual globe exists whose aim is not the representation of the planet. As more and more high-resolution satellite imagery and aerial photography become accessible for free, many of the latest online virtual globes are built to fetch and they include, ArcGIS Explorer a lightweight client for ArcGIS Server, supports WMS and many other GIS file formats. Bing Maps 3D interface runs inside Internet Explorer and Firefox, and uses NASA Blue Marble, bhuvan is an India-specific virtual globe. Cesium, a WebGL virtual globe and map engine, cesium is free and open-source software. Driveme. in is a street view application for India, earth3D, a program that visualizes the Earth in a real-time 3D view. It uses data from NASA, USGS, the CIA and the city of Osnabrück, earthBrowser, an Adobe Flash/AIR-based virtual globe with real-time weather forecasts, earthquakes, volcanoes, and webcams. G3M is an open source multiplatform advanced 3D visualization framework, allowing very high performance in mobile native development, Google Earth, satellite and aerial photos dataset with international road dataset, the first popular virtual globe along with NASA World Wind. MapJack is a map feature covering areas in Canada, France, Latvia, Macau, Malaysia, Puerto Rico, Singapore, Sweden, Thailand, Marble, part of KDE, with data provided by OpenStreetMap, as well as NASA Blue Marble, Next Generation and others. Marble is free and open-source software, NASA World Wind, USGS topographic maps and several satellite and aerial image datasets, the first popular virtual globe along with Google Earth. NORC is a street view web service for Central and Eastern Europe, openWebGlobe, a virtual globe SDK written in JavaScript using WebGL. OpenWebGlobe is free and open-source software, osgEarth is an open-source C++ SDK for global terrain rendering

Software license
–
A software license is a legal instrument governing the use or redistribution of software. Under United States copyright law all software is copyright protected, in code as also object code form. The only exception is software in the public domain, most distributed software can be categorized according to its license type. Two common categories for software under copyright law, and therefore with licenses which grant the licensee specific rights, are proprietary software and free, unlicensed software outside the copyright protection is either public domain software or software which is non-distributed, non-licensed and handled as internal business trade secret. Contrary to popular belief, distributed unlicensed software is copyright protected. Examples for this are unauthorized software leaks or software projects which are placed on public software repositories like GitHub without specified license. As voluntarily handing software into the domain is problematic in some international law domains, there are also licenses granting PD-like rights. Therefore, the owner of a copy of software is legally entitled to use that copy of software. Hence, if the end-user of software is the owner of the respective copy, as many proprietary licenses only enumerate the rights that the user already has under 17 U. S. C. §117, and yet proclaim to take away from the user. Proprietary software licenses often proclaim to give software publishers more control over the way their software is used by keeping ownership of each copy of software with the software publisher. The form of the relationship if it is a lease or a purchase, for example UMG v. Augusto or Vernor v. Autodesk. The ownership of goods, like software applications and video games, is challenged by licensed. The Swiss based company UsedSoft innovated the resale of business software and this feature of proprietary software licenses means that certain rights regarding the software are reserved by the software publisher. Therefore, it is typical of EULAs to include terms which define the uses of the software, the most significant effect of this form of licensing is that, if ownership of the software remains with the software publisher, then the end-user must accept the software license. In other words, without acceptance of the license, the end-user may not use the software at all, one example of such a proprietary software license is the license for Microsoft Windows. The most common licensing models are per single user or per user in the appropriate volume discount level, Licensing per concurrent/floating user also occurs, where all users in a network have access to the program, but only a specific number at the same time. Another license model is licensing per dongle which allows the owner of the dongle to use the program on any computer, Licensing per server, CPU or points, regardless the number of users, is common practice as well as site or company licenses

Computer program
–
A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the programs instructions in a processing unit. A computer program is written by a computer programmer in a programming language. From the program in its form of source code, a compiler can derive machine code—a form consisting of instructions that the computer can directly execute. Alternatively, a program may be executed with the aid of an interpreter. A part of a program that performs a well-defined task is known as an algorithm. A collection of programs, libraries and related data are referred to as software. Computer programs may be categorized along functional lines, such as software or system software. The earliest programmable machines preceded the invention of the digital computer, in 1801, Joseph-Marie Jacquard devised a loom that would weave a pattern by following a series of perforated cards. Patterns could be weaved and repeated by arranging the cards, in 1837, Charles Babbage was inspired by Jacquards loom to attempt to build the Analytical Engine. The names of the components of the device were borrowed from the textile industry. In the textile industry, yarn was brought from the store to be milled, the device would have had a store—memory to hold 1,000 numbers of 40 decimal digits each. Numbers from the store would then have then transferred to the mill. It was programmed using two sets of perforated cards—one to direct the operation and the other for the input variables, however, after more than 17,000 pounds of the British governments money, the thousands of cogged wheels and gears never fully worked together. During a nine-month period in 1842–43, Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea, the memoir covered the Analytical Engine. The translation contained Note G which completely detailed a method for calculating Bernoulli numbers using the Analytical Engine and this note is recognized by some historians as the worlds first written computer program. In 1936, Alan Turing introduced the Universal Turing machine—a theoretical device that can model every computation that can be performed on a Turing complete computing machine and it is a finite-state machine that has an infinitely long read/write tape. The machine can move the back and forth, changing its contents as it performs an algorithm

3D computer graphics
–
Such images may be stored for viewing later or displayed in real-time. 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire-frame model, 3D computer graphics are often referred to as 3D models. Apart from the graphic, the model is contained within the graphical data file. However, there are differences, a 3D model is the representation of any three-dimensional object. A model is not technically a graphic until it is displayed, a model can be displayed visually as a two-dimensional image through a process called 3D rendering or used in non-graphical computer simulations and calculations. With 3D printing, 3D models are rendered into a 3D physical representation of the model. William Fetter was credited with coining the term computer graphics in 1961 to describe his work at Boeing, 3D computer graphics software began appearing for home computers in the late 1970s. The earliest known example is 3D Art Graphics, a set of 3D computer graphics effects, written by Kazumasa Mitazawa, models can also be produced procedurally or via physical simulation. Basically, a 3D model is formed from points called vertices that define the shape, a polygon is an area formed from at least three vertexes. A polygon of n points is an n-gon, the overall integrity of the model and its suitability to use in animation depend on the structure of the polygons. Before rendering into an image, objects must be out in a scene. This defines spatial relationships between objects, including location and size, Animation refers to the temporal description of an object. These techniques are used in combination. As with animation, physical simulation also specifies motion, rendering converts a model into an image either by simulating light transport to get photo-realistic images, or by applying an art style as in non-photorealistic rendering. The two basic operations in realistic rendering are transport and scattering and this step is usually performed using 3D computer graphics software or a 3D graphics API. Altering the scene into a form for rendering also involves 3D projection. There are a multitude of websites designed to help, educate, some are managed by software developers and content providers, but there are standalone sites as well. These communities allow for members to seek advice, post tutorials, not all computer graphics that appear 3D are based on a wireframe model

Earth
–
Earth, otherwise known as the World, or the Globe, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets, according to radiometric dating and other sources of evidence, Earth formed about 4.54 billion years ago. Earths gravity interacts with objects in space, especially the Sun. During one orbit around the Sun, Earth rotates about its axis over 365 times, thus, Earths axis of rotation is tilted, producing seasonal variations on the planets surface. The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earths orientation on its axis, Earths lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earths surface is covered with water, mostly by its oceans, the remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earths polar regions are covered in ice, including the Antarctic ice sheet, Earths interior remains active with a solid iron inner core, a liquid outer core that generates the Earths magnetic field, and a convecting mantle that drives plate tectonics. Within the first billion years of Earths history, life appeared in the oceans and began to affect the Earths atmosphere and surface, some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earths distance from the Sun, physical properties, in the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species that lived on Earth are extinct. Estimates of the number of species on Earth today vary widely, over 7.4 billion humans live on Earth and depend on its biosphere and minerals for their survival. Humans have developed diverse societies and cultures, politically, the world has about 200 sovereign states, the modern English word Earth developed from a wide variety of Middle English forms, which derived from an Old English noun most often spelled eorðe. It has cognates in every Germanic language, and their proto-Germanic root has been reconstructed as *erþō, originally, earth was written in lowercase, and from early Middle English, its definite sense as the globe was expressed as the earth. By early Modern English, many nouns were capitalized, and the became the Earth. More recently, the name is simply given as Earth. House styles now vary, Oxford spelling recognizes the lowercase form as the most common, another convention capitalizes Earth when appearing as a name but writes it in lowercase when preceded by the. It almost always appears in lowercase in colloquial expressions such as what on earth are you doing, the oldest material found in the Solar System is dated to 4. 5672±0.0006 billion years ago. By 4. 54±0.04 Gya the primordial Earth had formed, the formation and evolution of Solar System bodies occurred along with the Sun

Satellite imagery
–
Satellite imagery consists of images of Earth or other planets collected by satellites. Imaging satellites are operated by governments and businesses around the world, Satellite imaging companies sell images under licence. Images are licensed to governments and businesses such as Apple Maps, the first images from space were taken on sub-orbital flights. The U. S-launched V-2 flight on October 24,1946 took one image every 1.5 seconds. With an apogee of 65 miles, these photos were from five times higher than the previous record, the first satellite photographs of Earth were made on August 14,1959 by the U. S. The first satellite photographs of the Moon might have made on October 6,1959 by the Soviet satellite Luna 3. The Blue Marble photograph was taken from space in 1972, and has very popular in the media. Also in 1972 the United States started the Landsat program, the largest program for acquisition of imagery of Earth from space, Landsat Data Continuity Mission, the most recent Landsat satellite, was launched on 11 February 2013. In 1977, the first real time satellite imagery was acquired by the United Statess KH-11 satellite system, all satellite images produced by NASA are published by NASA Earth Observatory and are freely available to the public. Several other countries have satellite imaging programs, and a collaborative European effort launched the ERS, there are also private companies that provide commercial satellite imagery. Images can be in visible colours and in other spectra, there are also elevation maps, usually made by radar images. Interpretation and analysis of imagery is conducted using specialized remote sensing applications. There are four types of resolution when discussing satellite imagery in remote sensing, spatial, spectral, temporal, and radiometric. GSD is a term containing the optical and systemic noise sources and is useful for comparing how well one sensor can see an object on the ground within a single pixel. For example, the GSD of Landsat is ~30m, which means the smallest unit that maps to a single pixel within an image is ~30m x 30m, the latest commercial satellite has a GSD of 0.41 m. This compares to a 0.3 m resolution obtained by some early military film based Reconnaissance satellite such as Corona, the resolution of satellite images varies depending on the instrument used and the altitude of the satellites orbit. For example, the Landsat archive offers repeated imagery at 30 meter resolution for the planet, Landsat 7 has an average return period of 16 days. For many smaller areas, images with resolution as high as 41 cm can be available, Satellite imagery is sometimes supplemented with aerial photography, which has higher resolution, but is more expensive per square meter

Aerial photography
–
Aerial photography is the taking of photographs of the ground from an elevated/direct-down position. Usually the camera is not supported by a ground-based structure, mounted cameras may be triggered remotely or automatically, hand-held photographs may be taken by a photographer. Aerial photography should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that chase, Aerial photography was first practiced by the French photographer and balloonist Gaspard-Félix Tournachon, known as Nadar, in 1858 over Paris, France. However, the photographs he produced no longer exist and therefore the earliest surviving aerial photograph is titled Boston, as the Eagle, taken by James Wallace Black and Samuel Archer King on October 13,1860, it depicts Boston from a height of 630m. Kite aerial photography was pioneered by British meteorologist E. D. Archibald in 1882 and he used an explosive charge on a timer to take photographs from the air. Frenchman Arthur Batut began using kites for photography in 1888, Samuel Franklin Cody developed his advanced Man-lifter War Kite and succeeded in interesting the British War Office with its capabilities. The first use of a motion picture camera mounted to an aircraft took place on April 24,1909 over Rome in the 3,28 silent film short. The use of aerial photography rapidly matured during the war, as aircraft were equipped with cameras to record enemy movements. At the start of the conflict, the usefulness of aerial photography was not fully appreciated, germany adopted the first aerial camera, a Görz, in 1913. The French began the war with several squadrons of Blériot observation aircraft equipped with cameras for reconnaissance, the French Army developed procedures for getting prints into the hands of field commanders in record time. Frederick Charles Victor Laws started aerial photography experiments in 1912 with No.1 Squadron of the Royal Flying Corps, in 1916 the Austro-Hungarian Monarchy made vertical camera axis aerial photos above Italy for map-making. The camera was inserted into the floor of the aircraft and could be triggered by the pilot at intervals. In January 1918, General Allenby used five Australian pilots from No.1 Squadron AFC to photograph a 624 square miles area in Palestine as an aid to correcting and improving maps of the Turkish front and this was a pioneering use of aerial photography as an aid for cartography. Beginning 5 January, they flew with an escort to ward off enemy fighters. The first commercial aerial photography company in the UK was Aerofilms Ltd, founded by World War I veterans Francis Wills, the company soon expanded into a business with major contracts in Africa and Asia as well as in the UK. Operations began from the Stag Lane Aerodrome at Edgware, using the aircraft of the London Flying School, subsequently, the Aircraft Manufacturing Company, hired an Airco DH.9 along with pilot entrepreneur Alan Cobham. From 1921, Aerofilms carried out vertical photography for survey and mapping purposes, during the 1930s, the company pioneered the science of photogrammetry, with the Ordnance Survey amongst the companys clients. One Fairchild aerial survey aircraft in 1935 carried unit that combined two synchronized cameras, and each camera having five six inch lenses with a ten-inch lenses, each photo covered two hundred and twenty five square miles

Geographic information system
–
A geographic information system is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries, in general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries, analyze spatial information, edit data in maps, Geographic information science is the science underlying geographic concepts, applications, and systems. GIS is a term that can refer to a number of different technologies, processes. It is attached to operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis, GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, all Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a real physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry, the first known use of the term geographic information system was by Roger Tomlinson in the year 1968 in his paper A Geographic Information System for Regional Planning. Tomlinson is also acknowledged as the father of GIS, previously, one of the first applications of spatial analysis in epidemiology is the 1832 Rapport sur la marche et les effets du choléra dans Paris et le département de la Seine. The French geographer Charles Picquet represented the 48 districts of the city of Paris by halftone color gradient according to the number of deaths by cholera per 1,000 inhabitants and this was one of the earliest successful uses of a geographic methodology in epidemiology. The early 20th century saw the development of photozincography, which allowed maps to be split into layers, for one layer for vegetation. This work was drawn on glass plates but later plastic film was introduced, with the advantages of being lighter, using less storage space and being less brittle. When all the layers were finished, they were combined into one using a large process camera. Once color printing came in, the idea was also used for creating separate printing plates for each color. Computer hardware development spurred by nuclear weapon research led to general-purpose computer mapping applications by the early 1960s, the year 1960 saw the development of the worlds first true operational GIS in Ottawa, Ontario, Canada by the federal Department of Forestry and Rural Development. A rating classification factor was added to permit analysis. CGIS was an improvement over computer mapping applications as it provided capabilities for overlay, measurement and it supported a national coordinate system that spanned the continent, coded lines as arcs having a true embedded topology and it stored the attribute and locational information in separate files. As a result of this, Tomlinson has become known as the father of GIS, CGIS lasted into the 1990s and built a large digital land resource database in Canada

Computer keyboard
–
In computing, a computer keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as a mechanical lever or electronic switch. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the input device for computers. A keyboard typically has characters engraved or printed on the keys, however, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs, other keys or simultaneous key presses can produce actions or execute computer commands. In normal usage, the keyboard is used as a text entry interface to type text and numbers into a word processor, in a modern computer, the interpretation of key presses is generally left to the software. A computer keyboard distinguishes each physical key from every other and reports all key presses to the controlling software, Keyboards are also used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently used keystroke combinations. A keyboard is used to give commands to the operating system of a computer, such as Windows Control-Alt-Delete combination. A command-line interface is a type of user interface operated entirely through a keyboard and it was through such devices that modern computer keyboards inherited their layouts. Earlier models were developed separately by individuals such as Royal Earl House, earlier, Herman Hollerith developed the first keypunch devices, which soon evolved to include keys for text and number entry akin to normal typewriters by the 1930s. From the 1940s until the late 1960s, typewriters were the means of data entry. The keyboard remained the primary, most integrated computer peripheral well into the era of personal computing until the introduction of the mouse as a device in 1984. By this time, text-only user interfaces with sparse graphics gave way to comparatively graphics-rich icons on screen, One factor determining the size of a keyboard is the presence of duplicate keys, such as a separate numeric keyboard, for convenience. A keyboard with few keys is called a keypad, another factor determining the size of a keyboard is the size and spacing of the keys. Reduction is limited by the consideration that the keys must be large enough to be easily pressed by fingers. Alternatively a tool is used for pressing small keys, standard alphanumeric keyboards have keys that are on three-quarter inch centers, and have a key travel of at least 0.150 inches. Desktop computer keyboards, such as the 101-key US traditional keyboards or the 104-key Windows keyboards, include characters, punctuation symbols, numbers. The internationally common 102/104 key keyboards have a left shift key. Also the enter key is usually shaped differently, computer keyboards are similar to electric-typewriter keyboards but contain additional keys, such as the command or Windows keys

Computer mouse
–
A computer mouse is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, physically, a mouse consists of an object held in ones hand, with one or more buttons. Mice often also other elements, such as touch surfaces and wheels. The earliest known publication of the mouse as referring to a computer pointing device is in Bill Englishs July 1965 publication. The plural for the rodent is always mice in modern usage. The plural of a mouse is mouses and mice according to most dictionaries. The first recorded usage is mice, the online Oxford Dictionaries cites a 1984 use. The trackball, a pointing device, was invented in 1944 by Ralph Benjamin as part of a World War II-era fire-control radar plotting system called Comprehensive Display System. Benjamin was then working for the British Royal Navy Scientific Service, Benjamins project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user with a joystick. Benjamin felt that a more elegant input device was needed and invented what they called a ball for this purpose. The device was patented in 1947, but only a prototype using a ball rolling on two rubber-coated wheels was ever built, and the device was kept as a military secret. Another early trackball was built by British electrical engineer Kenyon Taylor in collaboration with Tom Cranston, Taylor was part of the original Ferranti Canada, working on the Royal Canadian Navys DATAR system in 1952. DATAR was similar in concept to Benjamins display, the trackball used four disks to pick up motion, two each for the X and Y directions. When the ball was rolled, the pickup discs spun and contacts on their outer rim made periodic contact with wires, by counting the pulses, the physical movement of the ball could be determined. A digital computer calculated the tracks and sent the data to other ships in a task force using pulse-code modulation radio signals. This trackball used a standard Canadian five-pin bowling ball and it was not patented, since it was a secret military project. Douglas Engelbart of the Stanford Research Institute has been credited in published books by Thierry Bardini, Paul Ceruzzi, Howard Rheingold, Engelbart was also recognized as such in various obituary titles after his death in July 2013. That November, while attending a conference on computer graphics in Reno, Nevada, Engelbart began to ponder how to adapt the underlying principles of the planimeter to X-Y coordinate input

Smartphone
–
A smartphone is a mobile phone with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. Smartphones can access the Internet and can run a variety of third-party software components and they typically have a color display with a graphical user interface that covers more than 76% of the front surface. In 1999, the Japanese firm NTT DoCoMo released the first smartphones to achieve mass adoption within a country, smartphones became widespread in the late 2000s. Most of those produced from 2012 onward have high-speed mobile broadband 4G LTE, motion sensors, in the third quarter of 2012, one billion smartphones were in use worldwide. Global smartphone sales surpassed the sales figures for regular cell phones in early 2013, devices that combined telephony and computing were first conceptualized by Nikola Tesla in 1909 and Theodore Paraskevakos in 1971 and patented in 1974, and were offered for sale beginning in 1993. Paraskevakos was the first to introduce the concepts of intelligence, data processing and they were installed at Peoples Telephone Company in Leesburg, Alabama and were demonstrated to several telephone companies. The original and historic working models are still in the possession of Paraskevakos, the first mobile phone to incorporate PDA features was a prototype developed by Frank Canova in 1992 while at IBM and demonstrated that year at the COMDEX computer industry trade show. It included PDA features and other mobile applications such as maps, stock reports. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator, the Simon was the first commercially available device that could be properly referred to as a smartphone, although it was not called that in 1994. The term smart phone appeared in print as early as 1995, in the mid-late 1990s, many mobile phone users carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, BlackBerry OS or Windows CE/Pocket PC. These operating systems would later evolve into mobile operating systems, in March 1996, Hewlett-Packard released the OmniGo 700LX, a modified HP 200LX palmtop PC that supported a Nokia 2110 phone with ROM-based software to support it. It had a 640×200 resolution CGA compatible four-shade gray-scale LCD screen and could be used to place and receive calls and it was also 100% DOS5.0 compatible, allowing it to run thousands of existing software titles, including early versions of Windows. In August 1996, Nokia released the Nokia 9000 Communicator, a cellular phone based on the Nokia 2110 with an integrated PDA based on the PEN/GEOS3.0 operating system from Geoworks. The two components were attached by a hinge in what known as a clamshell design, with the display above. The PDA provided e-mail, calendar, address book, calculator and notebook applications, text-based Web browsing, when closed, the device could be used as a digital cellular phone. In June 1999 Qualcomm released the pdQ Smartphone, a CDMA digital PCS Smartphone with an integrated Palm PDA, subsequent landmark devices included, The Ericsson R380 by Ericsson Mobile Communications. The first device marketed as a smartphone, it combined the functions of a phone and PDA. The Kyocera 6035 introduced by Palm, Inc, combining a PDA with a mobile phone, it operated on the Verizon network, and supported limited Web browsing

Tablet computer
–
Tablets often come equipped with sensors, including digital cameras, a microphone, and an accelerometer so images on screens are always displayed upright. The touchscreen display uses the recognition of finger or stylus gestures to replace the mouse, trackpad, tablets are typically larger than smartphones or personal digital assistants with screens 7 inches or larger, measured diagonally. However much of a tablets functionality resembles that of a modern smartphone, tablets can be classified according to the presence and physical appearance of keyboards. Slates and booklets do not have a keyboard, and usually accept text. Hybrids, convertibles, and 2-in-1s do have physical keyboards, yet they also make use of virtual keyboards. Some 2-in-1s have processors and operating systems like a full laptop, most tablets can use separate keyboards connected using Bluetooth. The format was conceptualized in the century and prototyped and developed in the last two decades of that century. In April 2010, Apple released the iPad, the first mass-market tablet to achieve widespread popularity, thereafter in the 2010s, tablets rapidly rose in ubiquity and became a large product category used for both personal and workplace applications. The tablet computer and its operating system began with the development of pen computing. Throughout the 20th century devices with these characteristics have been imagined and created whether as blueprints, prototypes, a device more powerful than todays tablets appeared briefly in Jerry Pournelle and Larry Nivens The Mote in Gods Eye. Adults could also use a Dynabook, but the audience was children. In 1992, Atari showed developers the Stylus, later renamed ST-Pad, the ST-Pad was based on the TOS/GEM Atari ST Platform and prototyped early handwriting recognition. Shiraz Shivjis company Momentus demonstrated in the time a failed x86 MS-DOS based Pen Computer with its own GUI. In 1994, the European Union initiated the NewsPad project, inspired by Clarke, Acorn Computers developed and delivered an ARM-based touch screen tablet computer for this program, branding it the NewsPad, the project ended in 1997. During the November 2000 COMDEX, Microsoft used the term Tablet PC to describe a prototype handheld device they were demonstrating, all three products were based on extended versions of the MS-DOS operating system. In 1992, IBM announced and shipped to developers the 2521 ThinkPad, also based on PenPoint was AT&Ts EO Personal Communicator from 1993, which ran on AT&Ts own hardware, including their own AT&T Hobbit CPU. Apple Computer launched the Apple Newton personal digital assistant in 1993 and it utilised Apples own new Newton OS, initially running on hardware manufactured by Motorola and incorporating an ARM CPU, that Apple had specifically co-developed with Acorn Computers. The operating system and platform design were later licensed to Sharp and Digital Ocean, in 1996, Palm, Inc. released the first of the Palm OS based PalmPilot touch and stylus based PDA, the touch based devices initially incorporating a Motorola Dragonball CPU

Touchscreen
–
A touchscreen is a input and output device normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the processing system through simple or multi-touch gestures by touching the screen with a special stylus and/or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus/pen, the user can use the touchscreen to react to what is displayed and to control how it is displayed, for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather using a mouse, touchpad. Touchscreens are common in such as game consoles, personal computers, tablet computers, electronic voting machines, point of sale systems. They can also be attached to computers or, as terminals and they also play a prominent role in the design of digital appliances such as personal digital assistants and some e-readers. The popularity of smartphones, tablets, and many types of appliances is driving the demand and acceptance of common touchscreens for portable. The application of technology for air traffic control was described in an article published in 1968. Frank Beck and Bent Stumpe, engineers from CERN, developed a transparent touchscreen in the early 1970s, then manufactured by CERN, it was put to use in 1973. A resistive touchscreen was developed by American inventor George Samuel Hurst, the first version was produced in 1982. This arrangement can sense any fingertip-sized opaque object in close proximity to the screen, a similar touchscreen was used on the HP-150 starting in 1983, this was one of the worlds earliest commercial touchscreen computers. HP mounted their infrared transmitters and receivers around the bezel of a 9 Sony Cathode Ray Tube, in 1984, Fujitsu released a touch pad for the Micro 16, to deal with the complexity of kanji characters, which were stored as tiled graphics. In 1985, Sega released the Terebi Oekaki, also known as the Sega Graphic Board, for the SG-1000 video game console and it consisted of a plastic pen and a plastic board with a transparent window where the pen presses are detected. It was used primarily for a software application. A graphic touch tablet was released for the Sega AI Computer in 1986, touch-sensitive Control-Display Units were evaluated for commercial aircraft flight decks in the early 1980s. In 1985, the University of Toronto group including Bill Buxton developed a tablet that used capacitance rather than bulky camera-based optical sensing systems. In 1986, the first graphical point of sale software was demonstrated on the 16-bit Atari 520ST color computer and it featured a color touchscreen widget-driven interface. In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4x4 matrix, until 1988 touchscreens had the bad reputation of being imprecise

Stylus
–
A stylus, plural styli or styluses, is a writing utensil, or a small tool for some other form of marking or shaping, for example in pottery. It can also be an accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a ballpoint pen. Many styluses are heavily curved to be more easily. Another widely used writing tool is the used by blind users in conjunction with the slate for punching out the dots in Braille. Styluses were first used by the ancient Mesopotamians in order to write in cuneiform, cuneiform was entirely based on the wedge-shaped mark that the end of a cut reed made when pushed into a clay tablet, from Latin cuneus = wedge. The linear nature of the writing was also dictated by the use of the stylus, in Western Europe styluses were widely used until the late Middle Ages. For learning purposes the stylus was gradually replaced by a writing slate, from the mid-14th century improved water-powered paper mills produced large and cheap quantities of paper and the wax tablet and stylus disappeared completely from daily life. A different suggestion is that the word does not derive from the Greek word στῦλος and it signifies, An iron instrument, resembling a pencil in size and shape, used for writing upon waxed tablets. Thus, vertere stilum means to erase, and hence to correct, there exists minor controversy about the correct pluralization of stylus. Some assert that stylus is a loanword from Latin and should be pluralised as styli. However, stylus is an English word based on the Latin word stilus, occasionally the pluralisation stylii is seen. Styluses are still used in arts and crafts. Example situations, rubbing off dry transfer letters, tracing designs onto a new surface with carbon paper, styluses are also used to engrave into materials like metal or clay. Styluses are used to make dots as found in folk art, oaxaca dot art is created using styluses. In the sound recording industry, a stylus is a phonograph or gramophone needle used to play back sound on gramophone records, several technologies were used to record the sounds, beginning with wax cylinders, almost half a century before the invention of the magnetic cartridge. Nowadays mostly vinyl records are used, when playing the record, the stylus is placed in the grooves of the record. By then spinning the record, the start to vibrate caused by the shape of the grooves

Keyhole Markup Language
–
Keyhole Markup Language is an XML notation for expressing geographic annotation and visualization within Internet-based, two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer and it was created by Keyhole, Inc, which was acquired by Google in 2004. KML became a standard of the Open Geospatial Consortium in 2008. Google Earth was the first program able to view and graphically edit KML files, other projects such as Marble have also started to develop KML support. The KML file specifies a set of features for display in Here Maps, Google Earth, Maps and Mobile, each place always has a longitude and a latitude. Other data can make the more specific, such as tilt, heading, altitude. KML shares some of the same grammar as GML. Some KML information cannot be viewed in Google Maps or Mobile, KML files are very often distributed in KMZ files, which are zipped KML files with a. kmz extension. These must be legacy compression compatible, otherwise the. kmz file might not uncompress in all geobrowsers. The contents of a KMZ file are a single root KML document and optionally any overlays, images, icons, the root KML document by convention is a file named doc. kml at the root directory level, which is the file loaded upon opening. By convention the root KML document is at level and referenced files are in subdirectories. An example KML document is, The MIME type associated with KML is application/vnd. google-earth. kml+xml, the longitude, latitude components are as defined by the World Geodetic System of 1984. The vertical component is measured in meters from the WGS84 EGM96 Geoid vertical datum, if altitude is omitted from a coordinate string, e. g. then the default value of 0 is assumed for the altitude component, i. e. A formal definition of the reference system used by KML is contained in the OGC KML2.2 Specification. This definition references well-known EPSG CRS components, the KML2.2 specification was submitted to the Open Geospatial Consortium to assure its status as an open standard for all geobrowsers. In November 2007 a new KML2.2 Standards Working Group was established within OGC to formalize KML2.2 as an OGC standard. Comments were sought on the standard until January 4,2008. The OGC KML Standards Working Group finished working on change requests to KML2.2, the official OGC KML2.3 standard was published in August 4,2015

Blog
–
A blog is a discussion or informational website published on the World Wide Web consisting of discrete, often informal diary-style text entries. Posts are typically displayed in chronological order, so that the most recent post appears first. Until 2009, blogs were usually the work of an individual, occasionally of a small group. In the 2010s, multi-author blogs have developed, with posts written by large numbers of authors, MABs from newspapers, other media outlets, universities, think tanks, advocacy groups, and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other microblogging systems helps integrate MABs, Blog can also be used as a verb, meaning to maintain or add content to a blog. In the 2010s, the majority are interactive Web 2.0 websites, allowing visitors to leave online comments, in that sense, blogging can be seen as a form of social networking service. Indeed, bloggers do not only produce content to post on their blogs, however, there are high-readership blogs which do not allow comments. Many blogs provide commentary on a subject or topic, ranging from politics to sports. Others function as more personal online diaries, and others function more as online brand advertising of an individual or company. A typical blog combines text, digital images, and links to blogs, web pages. The ability of readers to leave publicly viewable comments, and interact with other commenters, is an important contribution to the popularity of many blogs, however, blog owners or authors often moderate and filter online comments to remove hate speech or other offensive content. Most blogs are primarily textual, although focus on art, photographs, videos, music. In education, blogs can be used as instructional resources and these blogs are referred to as edublogs. Microblogging is another type of blogging, featuring very short posts, on 16 February 2011, there were over 156 million public blogs in existence. On 20 February 2014, there were around 172 million Tumblr and 75.8 million WordPress blogs in existence worldwide, according to critics and other bloggers, Blogger is the most popular blogging service used today. However, Blogger does not offer public statistics, Technorati lists 1.3 million blogs as of February 22,2014. The term weblog was coined by Jorn Barger on 17 December 1997, the short form, blog, was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog Peterme. com in April or May 1999. Shortly thereafter, Evan Williams at Pyra Labs used blog as both a noun and verb and devised the term blogger in connection with Pyra Labs Blogger product, in the 1990s, Internet forum software, created running conversations with threads

Moon
–
The Moon is an astronomical body that orbits planet Earth, being Earths only permanent natural satellite. It is the fifth-largest natural satellite in the Solar System, following Jupiters satellite Io, the Moon is second-densest satellite among those whose densities are known. The average distance of the Moon from the Earth is 384,400 km, the Moon is thought to have formed about 4.51 billion years ago, not long after Earth. It is the second-brightest regularly visible celestial object in Earths sky, after the Sun and its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its prominence in the sky and its cycle of phases have made the Moon an important cultural influence since ancient times on language, calendars, art. The Moons gravitational influence produces the ocean tides, body tides, and this matching of apparent visual size will not continue in the far future. The Moons linear distance from Earth is currently increasing at a rate of 3.82 ±0.07 centimetres per year, since the Apollo 17 mission in 1972, the Moon has been visited only by uncrewed spacecraft. The usual English proper name for Earths natural satellite is the Moon, the noun moon is derived from moone, which developed from mone, which is derived from Old English mōna, which ultimately stems from Proto-Germanic *mǣnōn, like all Germanic language cognates. Occasionally, the name Luna is used, in literature, especially science fiction, Luna is used to distinguish it from other moons, while in poetry, the name has been used to denote personification of our moon. The principal modern English adjective pertaining to the Moon is lunar, a less common adjective is selenic, derived from the Ancient Greek Selene, from which is derived the prefix seleno-. Both the Greek Selene and the Roman goddess Diana were alternatively called Cynthia, the names Luna, Cynthia, and Selene are reflected in terminology for lunar orbits in words such as apolune, pericynthion, and selenocentric. The name Diana is connected to dies meaning day, several mechanisms have been proposed for the Moons formation 4.51 billion years ago, and some 60 million years after the origin of the Solar System. These hypotheses also cannot account for the angular momentum of the Earth–Moon system. This hypothesis, although not perfect, perhaps best explains the evidence, eighteen months prior to an October 1984 conference on lunar origins, Bill Hartmann, Roger Phillips, and Jeff Taylor challenged fellow lunar scientists, You have eighteen months. Go back to your Apollo data, go back to computer, do whatever you have to. Dont come to our conference unless you have something to say about the Moons birth, at the 1984 conference at Kona, Hawaii, the giant impact hypothesis emerged as the most popular. Afterward there were only two groups, the giant impact camp and the agnostics. Giant impacts are thought to have been common in the early Solar System, computer simulations of a giant impact have produced results that are consistent with the mass of the lunar core and the present angular momentum of the Earth–Moon system

Mars
–
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is referred to as the Red Planet because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet, Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan, there are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life. Future astrobiology missions are planned, including the Mars 2020 and ExoMars rovers, liquid water cannot exist on the surface of Mars due to low atmospheric pressure, which is about 6⁄1000 that of the Earths, except at the lowest elevations for short periods. The two polar ice caps appear to be largely of water. The volume of ice in the south polar ice cap, if melted. On November 22,2016, NASA reported finding a large amount of ice in the Utopia Planitia region of Mars. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior, Mars can easily be seen from Earth with the naked eye, as can its reddish coloring. Its apparent magnitude reaches −2.91, which is surpassed only by Jupiter, Venus, the Moon, optical ground-based telescopes are typically limited to resolving features about 300 kilometers across when Earth and Mars are closest because of Earths atmosphere. Mars is approximately half the diameter of Earth with an area only slightly less than the total area of Earths dry land. Mars is less dense than Earth, having about 15% of Earths volume and 11% of Earths mass, the red-orange appearance of the Martian surface is caused by iron oxide, or rust. It can look like butterscotch, other common colors include golden, brown, tan. Like Earth, Mars has differentiated into a metallic core overlaid by less dense materials. Current models of its interior imply a core with a radius of about 1,794 ±65 kilometers, consisting primarily of iron and this iron sulfide core is thought to be twice as rich in lighter elements than Earths. The core is surrounded by a mantle that formed many of the tectonic and volcanic features on the planet

Night sky
–
The term night sky refers to the sky as seen at night. The term is associated with astronomy, with reference to views of celestial bodies such as stars, the Moon. Natural light sources in a night sky include moonlight, starlight, the aurora borealis and aurora australis light up the skies of the Arctic and Antarctic circles respectively. Occasionally, a large coronal mass ejection from the Sun or simply high levels of solar wind extend the phenomenon toward the equator, the night sky and studies of it have a historical place in both ancient and modern cultures. In the past, for instance, farmers have used the state of the sky as a calendar to determine when to plant crops. Many cultures have drawn constellations between stars in the sky, using them in association with legends and mythology about their deities, the anciently developed belief of astrology is generally based on the belief that relationships between heavenly bodies influence or convey information about events on Earth. The scientific study of the sky and bodies observed within it, meanwhile. The visibility of objects in the night sky is affected by light pollution. The presence of the Moon in the sky has historically hindered astronomical observation by increasing the amount of ambient lighting. With the advent of light sources, however, light pollution has been a growing problem for viewing the night sky. The intensity of the sky varies greatly over the day and the cause differs as well. During daytime when the sun is above the horizon direct scattering of sunlight is the dominant source of light. In twilight, the period of time between sunset and sunrise, the situation is complicated and a further differentiation is required. Twilight is divided in three segments according to how far the sun is below the horizon in segments of 6°, after sunset the civil twilight sets in, and ends when the sun drops more than 6° below the horizon. This is followed by the nautical twilight, when the sun reaches heights of -6° and -12°, when the sun drops more than 18° below the horizon the sky generally attains its minimum brightness. Several sources can be identified as the source of the brightness of the sky, namely airglow, indirect scattering of sunlight, scattering of starlight. Stars appear as, depending on how dark the sky is, to the naked eye, they all appear to be equidistant on a dome above the earth because stars are much too far away for stereopsis to offer any depth cues. Visible stars range in color from blue to red, but with small points of faint light

Flight simulator
–
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. An area of training was for air gunnery handled by the pilot or a specialist air gunner, firing at a moving target requires aiming ahead of the target to allow for the time the bullets require to reach the vicinity of the target. This is sometimes also called deflection shooting and requires skill and practice, during World War I, some ground-based simulators were developed to teach this skill to new pilots. The best-known early flight simulation device was the Link Trainer, produced by Edwin Link in Binghamton, New York, USA and he later patented his design, which was first available for sale in 1929. The Link Trainer was a metal frame flight simulator usually painted in its well-known blue color. Some of these early war era flight simulators still exist, the Link family firm in Binghamton manufactured player pianos and organs, and Ed Link was therefore familiar with such components as leather bellows and reed switches. His design had a motion platform driven by inflatable bellows which provided pitch. A vacuum motor similar to those used in player pianos rotated the platform, a generic replica cockpit with working instruments was mounted on the motion platform. When the cockpit was covered, pilots could practice flying by instruments in a safe environment, the motion platform gave the pilot cues as to real angular motion in pitch, roll and yaw. Initially, aviation flight schools showed little interest in the Link Trainer, Link also demonstrated his trainer to the U. S. Army Air Force, but with no result. However, the changed in 1934 when the Army Air Force was given a government contract to fly the postal mail. This included having to fly in bad weather as well as good, during the first weeks of the mail service, nearly a dozen Army pilots were killed. The Army Air Force hierarchy remembered Ed Link and his trainer, Link flew in to meet them at Newark Field in New Jersey, and they were impressed by his ability to arrive on a day with poor visibility, due to practice on his training device. The result was that the USAAF purchased six Link Trainers, the principal pilot trainer used during World War II was the Link Trainer. Almost all US Army Air Force pilots were trained in a Link Trainer, a different type of World War II trainer was used for navigating at night by the stars. The Celestial Navigation Trainer of 1941 was 13.7 m high and it enabled sextants to be used for taking star shots from a projected display of the night sky. In 1954 United Airlines bought four flight simulators at a cost of $3 million from Curtiss-Wright that were similar to the models, with the addition of visuals, sound. This was the first of modern flight simulators for commercial aircraft

Panoramio
–
Panoramio was a geo-located tagging, photo sharing mashup owned by Google. Accepted geo-located tag photos, uploaded to the site could be accessed as a layer in Google Earth and Google Maps, the sites goal was to allow Google Earth users to learn more about a given area by viewing the photos that other users had taken at that place. The website was available in several languages, the headquarters of Panoramio were originally located in Zurich, in the office building of Google Switzerland but subsequently were moved to Mountain View, California, USA. Panoramio commenced in 2005 and officially closed on November 4,2016, Panoramio was started in the summer of 2005 by Joaquín Cuenca Abela and Eduardo Manchón Aguilar, two Spanish entrepreneurs. It was officially launched on October 3,2005, and by March 19,2007, three months later, on June 27,2007, the number of photos reached two million. After a further four months, on October 25,2007, in October 2006, Google began approaches to acquire Panoramio but these were rebuffed. However, on May 30,2007, Google announced plans to acquire the website, Eduardo Manchón left the company in January 2010 to focus on his new project Askaro. He was replaced by Gerard Sanz Viñas, Joaquín Cuenca left the company in May 2010. As of September 2014, Panoramio was a community of several million people and was available in 47 languages. In May 2015, the number of uploaded photos exceeded 120 million. On October 8,2016, the number of uploaded photos was 94,370,531 by 4,159,004 users. On September 16,2014, it was announced, that Google intended to close Panoramio, during the migration important Panoramio features, such as comments, favorite photographers and groups would disappear. It requested that Google refrain from closing Panoramio, the information about the Panoramio protest and petition, quickly made headlines on international media. Panoramios strength had been that many geo-positioned Panoramio images were selected to appear on Google Earth software, however, photos selected for Google Earth since May 14,2015 did not appear on the desktop version of Google Earth. Google did not publicly acknowledge this decision nor did the Company explain the reason for it, on June 2,2015, it was suddenly announced that Googles plans for Panoramio were revised and that it would continue to operate until a better solution is developed. Achieving this balance can be a challenge, especially when publishing tools are managed under separate products, such as Panoramio, Views, Google+ and Google Maps. So today, after listening to community feedback about the future of the platform, instead of aligning the community with Views, we’ve gone back to the drawing board to work on a more integrated solution that supports you and your content directly within Google Maps. We’ll be taking the time to get this right as we build a solution that strives to meet the majority of your needs

Wikipedia
–
Wikipedia is a free online encyclopedia that aims to allow anyone to edit articles. Wikipedia is the largest and most popular reference work on the Internet and is ranked among the ten most popular websites. Wikipedia is owned by the nonprofit Wikimedia Foundation, Wikipedia was launched on January 15,2001, by Jimmy Wales and Larry Sanger. Sanger coined its name, a portmanteau of wiki and encyclopedia, There was only the English language version initially, but it quickly developed similar versions in other languages, which differ in content and in editing practices. With 5,377,348 articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias, in 2005, Nature published a peer review comparing 42 science articles from Encyclopædia Britannica and Wikipedia, and found that Wikipedias level of accuracy approached Encyclopædia Britannicas. Other collaborative online encyclopedias were attempted before Wikipedia, but none were so successful, Wikipedia began as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. Nupedia was founded on March 9,2000, under the ownership of Bomis and its main figures were Jimmy Wales, the CEO of Bomis, and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia. Nupedia was licensed initially under its own Nupedia Open Content License, while Wales is credited with defining the goal of making a publicly editable encyclopedia, Sanger is credited with the strategy of using a wiki to reach that goal. On January 10,2001, Sanger proposed on the Nupedia mailing list to create a wiki as a project for Nupedia. Wikipedia was launched on January 15,2001, as a single English-language edition at www. wikipedia. com, Wikipedias policy of neutral point-of-view was codified in its first months. Otherwise, there were few rules initially and Wikipedia operated independently of Nupedia. Originally, Bomis intended to make Wikipedia a business for profit, Wikipedia gained early contributors from Nupedia, Slashdot postings, and web search engine indexing. By August 8,2001, Wikipedia had over 8,000 articles, on September 25,2001, Wikipedia had over 13,000 articles. By the end of 2001, it had grown to approximately 20,000 articles and 18 language editions and it had reached 26 language editions by late 2002,46 by the end of 2003, and 161 by the final days of 2004. Nupedia and Wikipedia coexisted until the servers were taken down permanently in 2003. Citing fears of commercial advertising and lack of control in Wikipedia and these moves encouraged Wales to announce that Wikipedia would not display advertisements, and to change Wikipedias domain from wikipedia. com to wikipedia. org. Around 1,800 articles were added daily to the encyclopedia in 2006, a team at the Palo Alto Research Center attributed this slowing of growth to the projects increasing exclusivity and resistance to change. Others suggest that the growth is flattening naturally because articles that could be called low-hanging fruit—topics that clearly merit an article—have already been created, the Wall Street Journal cited the array of rules applied to editing and disputes related to such content among the reasons for this trend

Google Street View
–
Google Street View is a technology featured in Google Maps and Google Earth that provides panoramic views from positions along many streets in the world. It was launched in 2007 in several cities in the United States, streets with Street View imagery available are shown as blue lines on Google Maps. Google Street View displays panoramas of stitched images, most photography is done by car, but some is done by trekker, tricycle, walking, boat, snowmobile, and underwater apparatus. Street View had its inception in 2001 with The Stanford CityBlock Project, the project ended in June 2006, and its technology was folded into StreetView. 2007, Launched on May 25 in the United States using Immersive Media technology,2008, In May Google announces that it was testing face-blurring technology on its photos of the busy streets of Manhattan. The technology uses an algorithm to search Googles image database for faces. Street View integrated into Google Earth 4.3, the Maps application on the Apple iPhone, in November, the drag and drop Pegman icon is introduced as the primary user interface element for connecting from Mapss 2D view into Street Views 3D view. When Pegman is dropped onto a set of coordinates in Google Maps for which Street View data is available, Street View opens. Smart Navigation introduced allowing users to navigate around the panoramas by double-clicking with their cursor on any place or object they want to see,2010, Indoor views of businesses available. Google invites users to contribute panoramas of their own using gadgets with Android 4.2, Google highlights user-contributed panoramas with blue circle icons on Maps. The company also created a website to highlight places in the world where one can find them,2013, Business interior views are shown as small orange circles. Businesses such as shops, cafés and other premises can pay a photographer to take images of the interior of their premises which are then included in Street View. Google sets up program to let third parties borrow the Street View Trekker,2014, Street-level imagery from the past can now be seen, if available for a given street view. 2015, A partnership was announced between Street View and the monitoring company Aclima. Cars began carrying sensors to detect such as nitrogen dioxide, ozone. In October, support for Google Cardboard was announced allowing users to explore street view in 360 degree virtual reality, Street View is available as a component of Google Maps, as a web application, and as a mobile application for Android and iOS. Originally, Google Maps used Adobe Flash for Street View, Google overhauled Google Maps in 2013. The newer version uses JavaScript extensively and provides a JavaScript application programming interface, at the time of their release, the new Google Maps and Street View are measured slower than the old version in various setups

Privacy
–
Privacy is the ability of an individual or group to seclude themselves, or information about themselves, and thereby express themselves selectively. The boundaries and content of what is considered private differ among cultures and individuals, when something is private to a person, it usually means that something is inherently special or sensitive to them. The domain of privacy partially overlaps security, which can include the concepts of appropriate use, Privacy may also take the form of bodily integrity. The right not to be subjected to unsanctioned invasion of privacy by the government, corporations or individuals is part of many countries privacy laws, almost all countries have laws which in some way limit privacy. An example of this would be law concerning taxation, which require the sharing of information about personal income or earnings. Privacy may be sacrificed, normally in exchange for perceived benefits and very often with specific dangers and losses. Research shows that people are willing to voluntarily sacrifice privacy if the data gatherer is seen to be transparent as to what information is gathered. In the business world, a person may volunteer personal details in order to gamble on winning a prize, a person may also disclose personal information as part of being an executive for a publicly traded company in the USA pursuant to federal securities law. Personal information which is shared but subsequently stolen or misused can lead to identity theft. According to some researchers, this concept sets Anglo-American culture apart even from Western European cultures such as French or Italian, Most cultures, however, recognize the ability of individuals to withhold certain parts of their personal information from wider society—closing the door to ones home, for example. Such languages either use a complex description to translate the term or borrow from English privacy, the difference is sometimes expressed humorously as when I withhold information, it is privacy, when you withhold information, it is secrecy. On December 15,1890, Samuel Warren and Louis Brandeis published the article of the law called The right to privacy, a broad multicultural literary tradition going to the beginnings of recorded history discusses the concept of privacy. Warren and Louis Brandeis wrote The Right to Privacy, an article in which argued for the right to be let alone. Limited access refers to an ability to participate in society without having other individuals. Various theorists have imagined privacy as a system for limiting access to personal information. Charles Fried said that Privacy is not simply an absence of information about us in the minds of others, control over personal information is one of the more popular theories of the meaning of privacy. Alan Westin defined four states—or experiences—of privacy, solitude, intimacy, anonymity, solitude is a physical separation from others. Intimacy is a close, relaxed, and frank relationship between two or more individuals that results from the seclusion of a pair or small group of individuals, anonymity is the desire of individuals for times of public privacy

National security
–
The concept developed all in the United States after World War II. Accordingly, in order to possess national security, a nation needs to possess economic security, energy security, environmental security, the variety of definitions provide an overview of the many usages of this concept. National security objectively means the absence of threats to acquired values and subjectively, in 1990, Harvard University history professor Charles Maier defined national security through the lens of national power, National security. The variety of definitions provide an overview of the usages of this concept. National security objectively means the absence of threats to acquired values and subjectively, in 1990, Harvard University history professor Charles Maier defined national security through the lens of national power, National security. To be truly secure, a nation needs other forms of security, authorities differ in their choice of nation security elements. Besides the military aspect of security, the aspects of diplomacy or politics, society, environment, energy and natural resources, the elements of national security correlate closely to the concept of the elements of national power. Romm lists security from narcotic cartels, economic security, environmental security, military security is traditionally the earliest recognised form of national security. Military security implies the capability of a nation to defend itself, alternatively, military security implies the capability of a nation to enforce its policy choices by use of military force. The term military security is considered synonymous with security in much of its usage, diplomacy, negotiation and other interactions form the means of interaction between the objects. Historically, conquest of nations has made conquerors rich through plunder, access to new resources, economic security today forms, arguably, as important a part of national security as military security. The creation and protection of jobs that supply defense and non-defense needs are vital to national security, third world countries are less secure due to lack of employment for their citizens. Environmental security deals with issues which threaten the national security of a nation in any manner. The scope and nature of environmental threats to security and strategies to engage them are a subject of debate. While all environmental events are not considered significant of being categorised as threats, many transnational issues, romm classifies these as, Transnational environmental problems that threaten a nations security, in its broad defined sense. These include global environmental problems such as climate change due to warming, deforestation and loss of biodiversity. Environmental or resource problems that threaten a nations security, traditionally defined and these would be problems whose outcomes would result in conventional threats to national security as first or higher order outcomes. Environmentally threatening outcomes of warfare, e. g. Prabhakaran Paleris 2008 definition of a resource is. a support inventory, biotic or abiotic, renewable or expendable. for sustaining life at a heightened level of well-being

Mountain View, California
–
Mountain View is a city located in Santa Clara County, California, United States, named for its views of the Santa Cruz Mountains. From its origins as a stop, it grew to a large suburb with a pedestrian-friendly downtown, free wi-fi. The city borders Palo Alto and the San Francisco Bay to the north, Los Altos to the south, situated in the southern end of the San Francisco Peninsula in the San Francisco Bay Area, Mountain View is home to many high technology companies. In 1956, Shockley Semiconductor Laboratory, the first company to develop silicon semiconductor devices in what came to be known as Silicon Valley, was established in the city by William Shockley. Today, many of the largest technology companies in the world are headquartered in the city, including Google, Mozilla Foundation, Symantec, and Intuit. The original Byte Shop computer store was opened at 1063 El Camino Real, Mountain View by Paul Terrell, the Santa Clara Valley Transportation Authority integrates the city with the neighboring cities of Palo Alto, Los Altos, and Sunnyvale. The Mexican land grant of Rancho Pastoria de las Borregas was given in 1842 by Alta California Governor Juan Alvarado to Francisco Estrada. This grant was passed on to Mariano Castro, who sold half of the land to Martin Murphy, Jr. Eventually. First known as the center of Fremont Twp. before the first California 1852 census. Which meant that it was a predecessor to Mayfield and Palo Alto, Mountain View Station, officially named in 1864, had its beginnings earlier as a stagecoach stop on the route between San Francisco and San Jose, including the Butterfield Overland Mail. & El Camino Real of today, was closer to what was once the town center. The early pioneers were buried at the old cemetery between Mercy & Church, off Castro Street, now the present city Library and park. Reverend Henry Merrill Henderson, born in Maryland, age 35, arrived in Spring of 1852, with his family to meet with relatives Ricketts and he was the first Baptist minister in town and soon was going by horse to Half-Moon Bay, and McCartersville for services. His next-door neighbor arrived later that year, Seligman Weilheimer and brother Samuel from Dossenheim, Baden, Germany, who built at that property, the Fremont twp. population was about 560 by 1860, less Mayfield Post office section, which began north of present San Antonio Road. The towns early growth was due to agriculture, William Bubb later being a figure, buying 80 acres to farm in October 1851. His heirs expanded and intermarried in the area, agriculture remained the primary industry into the middle of the 20th century. The U. S. Navys adjacent 1000 acre Moffet Field Complex began after 1931, after World War II, the population grew significantly with the development of the aerospace and electronics industries. Between 1950 and 1960, the population grew from 6,563 to 30,889, today, high technology is the foundation of the local economy, and there exist few remnants of the citys agricultural past

Vicarious Visions
–
Vicarious Visions, Inc. is an American video game developer. Vicarious Visions games accounted for over $2.5 billion in retail sales, the headquarters of Vicarious Visions is located in Menands, New York.

NGA was known as the National Imagery and Mapping Agency until 2003. NGA headquarters is located at Fort Belvoir in Springfield, Virginia, the NGA campus, at 2.3 million square feet, is the third-largest government building in the Washington metropolitan area after The Pentagon and the Ronald Reagan Building. U. S. mapping and charting efforts remained relatively unchanged until World War I, using stereo viewers, photo-interpreters reviewed thousands of images. Many of these were of the target at different angles and times, giving rise to what became modern imagery analysis. The Engineer Reproduction Plant was the Army Corps of Engineerss first attempt to centralize mapping production, printing and it was located on the grounds of the Army War College in Washington, D. C. Previously, topographic mapping had largely been a function of individual field engineer units using field surveying techniques or copying existing or captured products, in addition, ERP assumed the supervision and maintenance of the War Department Map Collection, effective April 1,1939. With the advent of the Second World War aviation, field surveys began giving way to photogrammetry, photo interpretation, during wartime, it became increasingly possible to compile maps with minimal field work. Out of this emerged AMS, which absorbed the existing ERP in May 1942 and it was located at the Dalecarlia Site on MacArthur Blvd. just outside Washington, D. C. in Montgomery County, Maryland, and adjacent to the Dalecarlia Reservoir. AMS was designated as an Engineer field activity, effective July 1,1942, by General Order 22, OCE, the Army Map Service also combined many of the Armys remaining geographic intelligence organizations and the Engineer Technical Intelligence Division. The agencys credit union, Constellation Federal Credit Union, was chartered during the Army Map Service era and it has continued to serve all successive legacy agencies employees and their families. After the war, as capacity and range improved, the need for charts grew. The Army Air Corps established its map unit, which was renamed ACP in 1943 and was located in St. Louis, ACP was known as the U. S. Air Force Aeronautical Chart and Information Center from 1952 to 1972. A credit union was chartered for the ACP in 1948, called Aero Chart Credit Union and it was renamed Arsenal Credit Union in 1952, a nod to the St. Louis sites Civil War-era use as an arsenal. Shortly before leaving office in January 1961, President Dwight D. Eisenhower authorized the creation of the National Photographic Interpretation Center, lundahl, combining Central Intelligence Agency, Army, Navy, and Air Force assets to solve national intelligence problems. NPIC was a component of the CIAs Directorate of Science and Technology, NPIC first identified the Soviet Unions basing of missiles in Cuba in 1962. The Defense Mapping Agency was created on January 1,1972, dMAs birth certificate, DoD Directive 5105.40, resulted from a formerly classified Presidential directive, Organization and Management of the U. S. Foreign Intelligence Community, which directed the consolidation of mapping functions previously dispersed among the military services, DMA became operational on July 1,1972, pursuant to General Order 3, DMA. On Oct.1,1996, DMA was folded into the National Imagery, DMA was first headquartered at the United States Naval Observatory in Washington, D. C, then at Falls Church, Virginia

The GeForce outperformed existing products by a wide margin, due to the success of its products, Nvidia won the contract to develop the graphics hardware for Microsofts Xbox game console, which earned Nvidia a $200 million advance. However, the project drew the time of many of its best engineers away from other projects, in the short term this did not matter, and the GeForce2 GTS shipped in the summer of 2000. In December 2000, Nvidia reached an agreement to acquire the assets of its one-time rival 3dfx. The acquisition process was finalized in April 2002, in July 2002, Nvidia acquired Exluna for an undisclosed sum.

Their former slogans were make. believe, like. no. other, Sony has a weak tie to the SMFG keiretsu, the successor to the Mitsui keiretsu. Sony began in the wake of World War II, in 1946, Masaru Ibuka started an electronics shop in a department store building in Tokyo. The company had $530 in capital and a total of eight employees, in the following year he was joined by his colleague, Akio Morita, and they founded a company called Tokyo Tsushin Kogyo 東京通信工業. The company built Japans first tape recorder, called the Type-G, in 1958 the company changed its name to Sony. When Tokyo Tsushin Kogyo was looking for a name to use to market themselves, they strongly considered using their initials. The primary reason they did not is that the railway company Tokyo Kyuko was known as TTK, the company occasionally used the acronym Totsuko in Japan, but during his visit to the United States, Morita discovered that Americans had trouble pronouncing that name. Another early name that was tried out for a while was Tokyo Teletech until Akio Morita discovered that there was an American company already using Teletech as a brand name, the name Sony was chosen for the brand as a mix of two words. One was the Latin word sonus, which is the root of sonic and sound, and the other was sonny, a common slang term used in 1950s America to call a boy. In the 1950s Japan sonny boys, was a word into Japanese which connoted smart and presentable young men. The first Sony-branded product, the TR-55 transistor radio, appeared in 1955, at the time of the change, it was extremely unusual for a Japanese company to use Roman letters to spell its name instead of writing it in kanji. The move was not without opposition, TTKs principal bank at the time and they pushed for a name such as Sony Electronic Industries, or Sony Teletech. Akio Morita was firm, however, as he did not want the company tied to any particular industry. Eventually, both Ibuka and Mitsui Banks chairman gave their approval, according to Schiffer, Sonys TR-63 radio cracked open the U. S. market and launched the new industry of consumer microelectronics
