Smart card
–
A smart card, chip card, or integrated circuit card is any pocket-sized card that has embedded integrated circuits. Smart cards are made of plastic, generally polyvinyl chloride, but sometimes polyethylene terephthalate based polyesters, since April 2009, a Japanese company has manufactured reusable financial smart cards made from paper. Smart cards can be either contact or contactless smart card, Smart cards can provide personal identification, authentication, data storage, and application processing. Smart cards may provide strong security authentication for single sign-on within large organizations, in 1968 and 1969 Helmut Gröttrup and Jürgen Dethloff jointly filed patents for the automated chip card. Roland Moreno patented the memory card concept in 1974, an important patent for smart cards with a microprocessor and memory as used today was filed by Jürgen Dethloff in 1976 and granted as USP4105156 in 1978. Three years later, Motorola used this patent in its CP8, at that time, Bull had 1,200 patents related to smart cards. In 2001, Bull sold its CP8 division together with its patents to Schlumberger, in 2006, Axalto and Gemplus, at the time the worlds top two smart card manufacturers, merged and became Gemalto. The first mass use of the cards was as a card for payment in French pay phones. After the Télécarte, microchips were integrated into all French Carte Bleue debit cards in 1992, customers inserted the card into the merchants point of sale terminal, then typed the personal identification number, before the transaction was accepted. Only very limited transactions are processed without a PIN, smart-card-based electronic purse systems store funds on the card so that readers do not need network connectivity. They entered European service in the mid-1990s and they have been common in Germany, Austria, Belgium, France, the Netherlands, Switzerland, Norway, Sweden, Finland, UK, Denmark and Portugal. Since the 1990s, smart-cards have been the Subscriber Identity Modules used in European GSM mobile phone equipment, Mobile phones are widely used in Europe, so smart cards have become very common. Europay MasterCard Visa -compliant cards and equipment are widespread, the United States started using the EMV technology in 2014. Historically, in 1993 several international payment companies agreed to develop specifications for debit and credit cards. The original brands were MasterCard, Visa, and Europay, the first version of the EMV system was released in 1994. In 1998 the specifications became stable, eMVcos purpose is to assure the various financial institutions and retailers that the specifications retain backward compatibility with the 1998 version. EMVco upgraded the specifications in 2000 and 2004, EMV compliant cards were first accepted into Malaysia in 2005 and later into United States in 2014. MasterCard was the first company that was allowed to use the technology in the United States, the United States has felt pushed to use the technology because of the increase in identity theft

USB
–
It is currently developed by the USB Implementers Forum. USB was designed to standardize the connection of peripherals to personal computers. It has become commonplace on other devices, such as smartphones, PDAs, USB has effectively replaced a variety of earlier interfaces, such as serial ports and parallel ports, as well as separate power chargers for portable devices. Also, there are 5 modes of USB data transfer, in order of increasing bandwidth, Low Speed, Full Speed, High Speed, SuperSpeed, USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. Modes are identified by their names and icons, and the specifications suggests that plugs, unlike other data buses, USB connections are directed, with both upstream and downstream ports emanating from a single host. This applies to power, with only downstream facing ports providing power. Thus, USB cables have different ends, A and B, therefore, in general, each different format requires four different connectors, a plug and receptacle for each of the A and B ends. USB cables have the plugs, and the corresponding receptacles are on the computers or electronic devices, in common practice, the A end is usually the standard format, and the B side varies over standard, mini, and micro. The mini and micro formats also provide for USB On-The-Go with a hermaphroditic AB receptacle, the micro format is the most durable from the point of view of designed insertion lifetime. The standard and mini connectors have a lifetime of 1,500 insertion-removal cycles. Likewise, the component of the retention mechanism, parts that provide required gripping force, were also moved into plugs on the cable side. A group of seven companies began the development of USB in 1994, Compaq, DEC, IBM, Intel, Microsoft, NEC, a team including Ajay Bhatt worked on the standard at Intel, the first integrated circuits supporting USB were produced by Intel in 1995. The original USB1.0 specification, which was introduced in January 1996, Microsoft Windows 95, OSR2.1 provided OEM support for the devices. The first widely used version of USB was 1.1, the 12 Mbit/s data rate was intended for higher-speed devices such as disk drives, and the lower 1.5 Mbit/s rate for low data rate devices such as joysticks. Apple Inc. s iMac was the first mainstream product with USB, following Apples design decision to remove all legacy ports from the iMac, many PC manufacturers began building legacy-free PCs, which led to the broader PC market using USB as a standard. The USB2.0 specification was released in April 2000 and was ratified by the USB Implementers Forum at the end of 2001.1 specification, the USB3.0 specification was published on 12 November 2008. Its main goals were to increase the transfer rate, decrease power consumption, increase power output. USB3.0 includes a new, higher speed bus called SuperSpeed in parallel with the USB2.0 bus, for this reason, the new version is also called SuperSpeed

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

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

Central processing unit
–
The computer industry has used the term central processing unit at least since the early 1960s. The form, design and implementation of CPUs have changed over the course of their history, most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit chip. An IC that contains a CPU may also contain memory, peripheral interfaces, some computers employ a multi-core processor, which is a single chip containing two or more CPUs called cores, in that context, one can speak of such single chips as sockets. Array processors or vector processors have multiple processors that operate in parallel, there also exists the concept of virtual CPUs which are an abstraction of dynamical aggregated computational resources. Early computers such as the ENIAC had to be rewired to perform different tasks. Since the term CPU is generally defined as a device for software execution, the idea of a stored-program computer was already present in the design of J. Presper Eckert and John William Mauchlys ENIAC, but was initially omitted so that it could be finished sooner. On June 30,1945, before ENIAC was made, mathematician John von Neumann distributed the paper entitled First Draft of a Report on the EDVAC and it was the outline of a stored-program computer that would eventually be completed in August 1949. EDVAC was designed to perform a number of instructions of various types. Significantly, the programs written for EDVAC were to be stored in high-speed computer memory rather than specified by the wiring of the computer. This overcame a severe limitation of ENIAC, which was the considerable time, with von Neumanns design, the program that EDVAC ran could be changed simply by changing the contents of the memory. Early CPUs were custom designs used as part of a larger, however, this method of designing custom CPUs for a particular application has largely given way to the development of multi-purpose processors produced in large quantities. This standardization began in the era of discrete transistor mainframes and minicomputers and has accelerated with the popularization of the integrated circuit. The IC has allowed increasingly complex CPUs to be designed and manufactured to tolerances on the order of nanometers, both the miniaturization and standardization of CPUs have increased the presence of digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in electronic devices ranging from automobiles to cellphones, the so-called Harvard architecture of the Harvard Mark I, which was completed before EDVAC, also utilized a stored-program design using punched paper tape rather than electronic memory. Relays and vacuum tubes were used as switching elements, a useful computer requires thousands or tens of thousands of switching devices. The overall speed of a system is dependent on the speed of the switches, tube computers like EDVAC tended to average eight hours between failures, whereas relay computers like the Harvard Mark I failed very rarely. In the end, tube-based CPUs became dominant because the significant speed advantages afforded generally outweighed the reliability problems, most of these early synchronous CPUs ran at low clock rates compared to modern microelectronic designs. Clock signal frequencies ranging from 100 kHz to 4 MHz were very common at this time, the design complexity of CPUs increased as various technologies facilitated building smaller and more reliable electronic devices

StrongARM
–
The StrongARM is a family of computer microprocessors developed by Digital Equipment Corporation and manufactured in the late 1990s which implemented the ARM v4 instruction set architecture. It was later sold to Intel in 1997, who continued to manufacture it before replacing it with the XScale in the early 2000s, the StrongARM was a collaborative project between DEC and Advanced RISC Machines to create a faster ARM microprocessor. The StrongARM was designed to address the upper-end of the embedded market. Targets were devices such as personal digital assistants and set-top boxes. Traditionally, the division of DEC was located in Massachusetts. In order to access to the design talent in Silicon Valley, DEC opened a design center in Palo Alto. This design center was led by Dan Dobberpuhl and was the main site for the StrongARM project. Another design site which worked on the project was in Austin, Texas that was created by some ex-DEC designers returning from Apple Computer, the project was set up in 1995, and quickly delivered their first design, the SA-110. DEC agreed to sell StrongARM to Intel as part of a settlement in 1997. Intel used the StrongARM to replace their ailing line of RISC processors, the Austin design group spun off to become Alchemy Semiconductor, another start-up company designing MIPS SoCs for the hand-held market. A new StrongARM core was developed by Intel and introduced in 2000 as the XScale, the SA-110 was the first microprocessor in the StrongARM family. The first versions, operating at 100,160, and 200 MHz, were announced on 5 February 1996, when announced, samples of these versions were available, with volume production slated for mid-1996. Faster 166 and 233 MHz versions were announced on 12 September 1996, samples of these versions were available at announcement, with volume production slated for December 1996. Throughout 1996, the SA-110 was the highest performing microprocessor for portable devices, towards the end of 1996 it was a leading CPU for internet/intranet appliances and thin client systems. The SA-110s first design win was the Apple MessagePad 2000 and it was also used in a number of products including the Acorn Computers Risc PC and Eidos Optima video editing system. The SA-110s lead designers were Daniel W. Dobberpuhl, Gregory W. Hoeppner, Liam Madden, the SA-110 had a simple microarchitecture. It was a design that executed instructions in-order with a five-stage classic RISC pipeline. The microprocessor was partitioned into several blocks, the IBOX, EBOX, IMMU, DMMU, BIU, WB, the IBOX contained hardware that operated in the first two stages of the pipeline such as the program counter

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

Infrared
–
It extends from the nominal red edge of the visible spectrum at 700 nanometers, to 1000000 nm. Most of the radiation emitted by objects near room temperature is infrared. Like all EMR, IR carries radiant energy, and behaves both like a wave and like its quantum particle, the photon, slightly more than half of the total energy from the Sun was eventually found to arrive on Earth in the form of infrared. The balance between absorbed and emitted infrared radiation has an effect on Earths climate. Infrared radiation is emitted or absorbed by molecules when they change their rotational-vibrational movements and it excites vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared spectroscopy examines absorption and transmission of photons in the infrared range, Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected, Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatuses. Thermal-infrared imaging is used extensively for military and civilian purposes, military applications include target acquisition, surveillance, night vision, homing, and tracking. Humans at normal body temperature radiate chiefly at wavelengths around 10 μm, Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers to 1 mm. This range of wavelengths corresponds to a range of approximately 430 THz down to 300 GHz. Below infrared is the portion of the electromagnetic spectrum. Sunlight, at a temperature of 5,780 kelvins, is composed of near thermal-spectrum radiation that is slightly more than half infrared. At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level, of this energy,527 watts is infrared radiation,445 watts is visible light, and 32 watts is ultraviolet radiation. Nearly all the radiation in sunlight is near infrared, shorter than 4 micrometers. On the surface of Earth, at far lower temperatures than the surface of the Sun, almost all thermal radiation consists of infrared in mid-infrared region, much longer than in sunlight. Of these natural thermal radiation processes only lightning and natural fires are hot enough to produce much visible energy, thermal infrared radiation also has a maximum emission wavelength, which is inversely proportional to the absolute temperature of object, in accordance with Wiens displacement law. Therefore, the band is often subdivided into smaller sections. Due to the nature of the blackbody radiation curves, typical hot objects, such as exhaust pipes, the three regions are used for observation of different temperature ranges, and hence different environments in space

Lithium-ion battery
–
A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, the electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell. Lithium-ion batteries are common in home electronics and they are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, tiny memory effect and low self-discharge. Beyond consumer electronics, LIBs are also growing in popularity for military, battery electric vehicle, for example, lithium-ion batteries are becoming a common replacement for the lead–acid batteries that have been used historically for golf carts and utility vehicles. Chemistry, performance, cost and safety characteristics vary across LIB types, handheld electronics mostly use LIBs based on lithium cobalt oxide, which offers high energy density, but presents safety risks, especially when damaged. Lithium iron phosphate, lithium ion manganese oxide battery and lithium nickel manganese cobalt oxide offer lower energy density, such batteries are widely used for electric tools, medical equipment and other roles. NMC in particular is a contender for automotive applications. Lithium nickel cobalt aluminum oxide and lithium titanate are specialty designs aimed at particular niche roles, the newer lithium–sulfur batteries promise the highest performance-to-weight ratio. Lithium-ion batteries can pose unique safety hazards since they contain a flammable electrolyte, an expert notes If a battery cell is charged too quickly, it can cause a short circuit, leading to explosions and fires. Because of these risks, testing standards are more stringent than those for acid-electrolyte batteries, there have been battery-related recalls by some companies, including the 2016 Samsung Note 7 recall for battery fires. This article covers just the topics and general principles of lithium-ion batteries. Nearly all facets have elements that are impacted by currently very active development or research, a cell is a basic electrochemical unit that contains the basic components, such as electrodes, separator, and electrolyte. In the case of cells, this is the single cylindrical, prismatic or pouch unit. In this regard, the simplest battery is a cell with perhaps a small electronic circuit for protection. In many cases, distinguishing between cell and battery is not important, however, this should be done when dealing with specific applications, for example, battery electric vehicles, where battery may indicate a high voltage system of 400 V, and not a single cell. The term module is used as an intermediate topology, with the understanding that a battery pack is made of modules. In electrochemistry, the anode is the electrode where oxidation is taking place in the battery, i. e. electrons get free, however, this happens on opposite electrodes during charge vs. discharge. Historically, for lithium cells, which started as single use discharge cells and this is true on discharge, but with a rechargeable system, the negative electrode chemically becomes the cathode while charging

Open-source hardware
–
Open-source hardware, consists of physical artifacts of technology designed and offered by the open design movement. Both free and open-source software as well as open-source hardware is created by this open-source culture movement and it is sometimes, thus, referred to as FOSH. The term usually means that information about the hardware is easily discerned so that others can make it - coupling it closely to the maker movement, Hardware design, in addition to the software that drives the hardware, are all released under free/libre terms. The original sharer gains feedback and potentially improvements on the design from the FOSH community, there is now significant evidence that such sharing can drive a high return on investment for investors. Since the rise of reconfigurable programmable logic devices, sharing of logic designs has been a form of open-source hardware, instead of the schematics, hardware description language code is shared. HDL descriptions are used to set up system-on-a-chip systems either in field-programmable gate arrays or directly in application-specific integrated circuit designs. HDL modules, when distributed, are called semiconductor intellectual property cores, the first hardware focused open source activities were started around 1997 by Bruce Perens, creator of the Open Source Definition, co-founder of the Open Source Initiative, and a ham radio operator. He launched the Open Hardware Certification Program, which had the goal of allowing hardware manufacturers to self-certify their products as open, in early 1999, Sepehr Kiani, Ryan Vallance and Samir Nayfeh joined efforts to apply the open source philosophy to machine design applications. Together they established the Open Design Foundation as a non-profit corporation, but most of these activities faded out after a few years. In 2007, Perens reactivated the openhardware. org website, thus, Patrick McNamara founded the Open Hardware Foundation in 2007. The OSI president Eric S. Raymond expressed some concerns about certain aspects of the OHL, around 2010 in context of the Freedom Defined project, the Open Hardware Definition was created as collaborative work of many and is accepted as of 2016 by dozens of organizations and companies. In July 2011, CERN released an open source hardware license, while initially drafted to address CERN-specific concerns, such as tracing the impact of the organization’s research, in its current form it can be used by anyone developing open source hardware. Openhardware. org is not online and seems to have ceased activity, the OSHWA was established as an organization in June 2012 in Delaware and filed for tax exemption status in July 2013. After same debates about trademark interferences with the OSI, in 2012 the OSHWA, in 2012, after years of skepticism on the relevance of free hardware designs, the Free Software Foundation started the Respects Your Freedom computer hardware product certification program. It was intended to encourage the creation and sale of hardware that respects users freedom and privacy, also FSFs Replicant project suggested in 2016 an alternative free hardware definition, derived from the FSFs four freedoms. Rather than creating a new license, some hardware projects simply use existing, free. These licenses may not accord well with patent law, later, several new licenses have been proposed, designed to address issues specific to hardware designs. In these licenses, many of the principles expressed in open-source software licenses have been ported to their counterpart hardware projects

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Personal computer
–
A personal computer is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a end-user, rather than by an expert or technician. In the 2010s, PCs are typically connected to the Internet, allowing access to the World Wide Web, personal computers may be connected to a local area network, either by a cable or a wireless connection. In the 2010s, a PC may be, a multi-component desktop computer, designed for use in a location a laptop computer, designed for easy portability or a tablet computer. In the 2010s, PCs run using a system, such as Microsoft Windows, Linux. The very earliest microcomputers, equipped with a front panel, required hand-loading of a program to load programs from external storage. Before long, automatic booting from permanent read-only memory became universal, in the 2010s, users have access to a wide range of commercial software, free software and free and open-source software, which are provided in ready-to-run or ready-to-compile form. Since the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the computer market, first with MS-DOS. Alternatives to Microsofts Windows operating systems occupy a minority share of the industry and these include Apples OS X and free open-source Unix-like operating systems such as Linux and Berkeley Software Distribution. Advanced Micro Devices provides the alternative to Intels processors. PC is an initialism for personal computer, some PCs, including the OLPC XOs, are equipped with x86 or x64 processors but not designed to run Microsoft Windows. PC is used in contrast with Mac, an Apple Macintosh computer and this sense of the word is used in the Get a Mac advertisement campaign that ran between 2006 and 2009, as well as its rival, Im a PC campaign, that appeared in 2008. Since Apples transition to Intel processors starting 2005, all Macintosh computers are now PCs, the “brain” may one day come down to our level and help with our income-tax and book-keeping calculations. But this is speculation and there is no sign of it so far, in the history of computing there were many examples of computers designed to be used by one person, as opposed to terminals connected to mainframe computers. Using the narrow definition of operated by one person, the first personal computer was the ENIAC which became operational in 1946 and it did not meet further definitions of affordable or easy to use. An example of an early single-user computer was the LGP-30, created in 1956 by Stan Frankel and used for science and it came with a retail price of $47, 000—equivalent to about $414,000 today. Introduced at the 1965 New York Worlds Fair, the Programma 101 was a programmable calculator described in advertisements as a desktop computer. It was manufactured by the Italian company Olivetti and invented by the Italian engineer Pier Giorgio Perotto, the Soviet MIR series of computers was developed from 1965 to 1969 in a group headed by Victor Glushkov

Trademark
–
The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, for the sake of corporate identity, trademarks are often displayed on company buildings. A trademark identifies the owner of a particular product or service. The unauthorized usage of trademarks by producing and trading counterfeit consumer goods is known as brand piracy, the owner of a trademark may pursue legal action against trademark infringement. Most countries require formal registration of a trademark as a precondition for pursuing this type of action, the United States, Canada and other countries also recognize common law trademark rights, which means action can be taken to protect an unregistered trademark if it is in use. Still, common law trademarks offer the holder in general less legal protection than registered trademarks. A trademark may be designated by the symbols, ™ ℠ ® A trademark is typically a name, word, phrase, logo, symbol, design, image. There is also a range of non-conventional trademarks comprising marks which do not fall into these categories, such as those based on colour, smell. Trademarks which are considered offensive are often rejected according to a nations trademark law, the term trademark is also used informally to refer to any distinguishing attribute by which an individual is readily identified, such as the well-known characteristics of celebrities. When a trademark is used in relation to services rather than products, it may sometimes be called a service mark, in other words, trademarks serve to identify a particular business as the source of goods or services. The use of a trademark in this way is known as trademark use, certain exclusive rights attach to a registered mark. Different goods and services have been classified by the International Classification of Goods, in trademark treatises it is usually reported that blacksmiths who made swords in the Roman Empire are thought of as being the first users of trademarks. Other notable trademarks that have used for a long time include Löwenbräu. The first trademark legislation was passed by the Parliament of England under the reign of King Henry III in 1266, the first modern trademark laws emerged in the late 19th century. In France the first comprehensive system in the world was passed into law in 1857 with the Manufacture. In Britain, the Merchandise Marks Act 1862 made it an offense to imitate anothers trade mark with intent to defraud or to enable another to defraud. In 1875 the Trade Marks Registration Act was passed which allowed formal registration of marks at the UK Patent Office for the first time. Registration was considered to comprise prima facie evidence of ownership of a trade mark, in the United States, Congress first attempted to establish a federal trademark regime in 1870

Software
–
Computer software, or simply software, is that part of a computer system that consists of data or computer instructions, in contrast to the physical hardware from which the system is built. In computer science and software engineering, computer software is all information processed by computer systems, programs, computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be used on its own. At the lowest level, executable code consists of machine language instructions specific to an individual processor—typically a central processing unit, a machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a storage location in the computer—an effect that is not directly observable to the user. An instruction may also cause something to appear on a display of the computer system—a state change which should be visible to the user. The processor carries out the instructions in the order they are provided, unless it is instructed to jump to a different instruction, the majority of software is written in high-level programming languages that are easier and more efficient for programmers, meaning closer to a natural language. High-level languages are translated into machine language using a compiler or an interpreter or a combination of the two, an outline for what would have been the first piece of software was written by Ada Lovelace in the 19th century, for the planned Analytical Engine. However, neither the Analytical Engine nor any software for it were ever created, the first theory about software—prior to creation of computers as we know them today—was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem. This eventually led to the creation of the academic fields of computer science and software engineering. Computer science is more theoretical, whereas software engineering focuses on practical concerns. However, prior to 1946, software as we now understand it—programs stored in the memory of stored-program digital computers—did not yet exist, the first electronic computing devices were instead rewired in order to reprogram them. On virtually all platforms, software can be grouped into a few broad categories. There are many different types of software, because the range of tasks that can be performed with a modern computer is so large—see list of software. System software includes, Operating systems, which are collections of software that manage resources and provides common services for other software that runs on top of them. Supervisory programs, boot loaders, shells and window systems are parts of operating systems. In practice, an operating system bundled with additional software so that a user can potentially do some work with a computer that only has an operating system. Device drivers, which operate or control a particular type of device that is attached to a computer, utilities, which are computer programs designed to assist users in the maintenance and care of their computers

GNU
–
GNU /ɡnuː/ is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Projects own GPL, GNU is a recursive acronym for GNUs Not Unix. Chosen because GNUs design is Unix-like, but differs from Unix by being free software, the GNU project includes an operating system kernel, GNU HURD, which was the original focus of the Free Software Foundation. However, non-GNU kernels, most famously Linux, can also be used with GNU software, and since the kernel is the least mature part of GNU, the combination of GNU software and the Linux kernel is commonly known as Linux. Richard Stallman, the founder of the project, views GNU as a means to a social end. unix-wizards. Software development began on January 5,1984, when Stallman quit his job at the Lab so that they could not claim ownership or interfere with distributing GNU components as free software, Richard Stallman chose the name by using various plays on words, including the song The Gnu. The goal was to bring a free software operating system into existence. This philosophy was published as the GNU Manifesto in March 1985. It was thus decided that the development would be started using C and Lisp as system programming languages, at the time, Unix was already a popular proprietary operating system. The design of Unix was modular, so it could be reimplemented piece by piece, in October 1985, Stallman set up the Free Software Foundation. In the late 1980s and 1990s, the FSF hired software developers to write the software needed for GNU, as GNU gained prominence, interested businesses began contributing to development or selling GNU software and technical support. The most prominent and successful of these was Cygnus Solutions, now part of Red Hat, GNU developers have contributed to Linux ports of GNU applications and utilities, which are now also widely used on other operating systems such as BSD variants, Solaris and macOS. Many GNU programs have been ported to other operating systems, including proprietary platforms such as Microsoft Windows, GNU programs have been shown to be more reliable than their proprietary Unix counterparts. As of November 2015, there are a total of 466 GNU packages hosted on the official GNU development site. With the April 30,2015 release of the Debian GNU/HURD2015 distro, GNU OS now provides the components to assemble a system that users can install. This includes the GNU Hurd kernel, that is currently in a pre-production state, the Hurd status page states that it may not be ready for production use, as there are still some bugs and missing features. However, it should be a base for further development. Due to Hurd not being ready for use, in practice these operating systems are Linux distributions

PalmPilot
–
The PalmPilot Personal and PalmPilot Professional are the second generation of Palm PDA devices produced by Palm Inc. These devices were launched on March 10,1997, Palm also sold the 10201U modem at 14.4 kbit/s, introduced at a price of $129. An upgrade kit was available, which allowed users of the earlier Pilot 1000/5000 devices to upgrade the OS, ROM. Initially suggested retail prices upon launch were $399 for the PalmPilot Professional, $299 for the PalmPilot Personal, Upgrade kits were also available to existing registered Pilot users for $99 for a limited time after the launch. These kits included IR capability, a new plastic memory door to accommodate the IR diodes, a card with 1 MB, the new ROM for Palm OS2.0. U. S. Robotics Announces Two New Models of the Best Selling Pilot Connected Organizer - Press Release, Palm support Palm OS2.05 Update

Stylus (computing)
–
In computing, a stylus is a small pen-shaped instrument that is used to input commands to a computer screen, mobile device or graphics tablet. With touchscreen devices, a user places a stylus on the surface of the screen to draw or make selections by tapping the stylus on the screen. In this manner, the stylus can be used instead of a mouse or trackpad as a pointing device, pen-like input devices which are larger than a stylus, and offer increased functionality such as programmable buttons, pressure sensitivity and electronic erasers, are often known as digital pens. The stylus is the input device for personal digital assistants. It is used on the Nintendo DS and 3DS handheld game consoles, some smartphones, such as Windows Mobile phones, require a stylus for accurate input. Also the stylus is used in the famous Galaxy Note series manufactured by Samsung Electronics, graphics tablets use a stylus containing circuitry, to allow multi-function buttons on the barrel of the pen or stylus to transmit user actions to the tablet. Most tablets detect varying degrees of pressure sensitivity, e. g. for use in a program to vary line thickness or color density. Beyond the side of the mechanism, there has been a need for the physical output of the stylus. The first use of a stylus in a device was the Styalator

Handwriting recognition
–
Handwriting recognition is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the text may be sensed off line from a piece of paper by optical scanning or intelligent word recognition. Alternatively, the movements of the pen tip may be sensed on line, for example by a computer screen surface. Handwriting recognition principally entails optical character recognition, however, a complete handwriting recognition system also handles formatting, performs correct segmentation into characters and finds the most plausible words. Off-line handwriting recognition involves the conversion of text in an image into letter codes which are usable within computer. The data obtained by this form is regarded as a representation of handwriting. Off-line handwriting recognition is difficult, as different people have different handwriting styles. And, as of today, OCR engines are primarily focused on machine printed text, narrowing the problem domain often helps increase the accuracy of handwriting recognition systems. ZIP code, for example, would contain only the characters 0-9 and this fact would reduce the number of possible identifications. Primary techniques, Specifying specific character ranges Utilization of specialized forms Off-line character recognition often involves scanning a form or document written sometime in the past and this means the individual characters contained in the scanned image will need to be extracted. Tools exist that are capable of performing this step, however, there are several common imperfections in this step. The most common is when characters that are connected are returned as a single containing both characters. This causes a problem in the recognition stage. Yet many algorithms are available that reduce the risk of connected characters, after the extraction of individual characters occurs, a recognition engine is used to identify the corresponding computer character. Several different recognition techniques are currently available, neural network recognizers learn from an initial image training set. The trained network then makes the character identifications, each neural network uniquely learns the properties that differentiate training images. It then looks for similar properties in the image to be identified. Neural networks are quick to set up, however, they can be if they learn properties that are not important in the target data

Infrared Data Association
–
The Infrared Data Association is an industry-driven interest group that was founded in 1993 by around 50 companies. IrDA provides specifications for a set of protocols for wireless infrared communications. The main reason for using IrDA had been wireless data transfer over the “last one meter” using point-and-shoot principles, thus, it has been implemented in portable devices such as mobile telephones, laptops, cameras, printers, and medical devices. Main characteristics of this kind of optical communication is physically secure data transfer, line-of-sight. The mandatory IrPHY is the layer of the IrDA specifications. It comprises optical link definitions, modulation, coding, cyclic redundancy check and the framer. Different data rates use different modulation/coding schemes, SIR,9. 6–115.2 kbit/s, asynchronous, RZI, UART-like, 3/16 pulse MIR,0. 576–1.2 m, the 10 GigaIR also define new usage models that supports higher link distances up to several meters. Additionally, bigger blocks of data can be transferred by sending multiple frames consecutively and this can be adjusted with a parameter called window size. Finally, data blocks up to 8 MB can be sent at once, combined with a low bit error rate of generally <10−9, that communication could be very efficient compared to other wireless solutions. IrDA transceivers communicate with infrared pulses in a cone that extends at least 15 degrees half angle off center, in practice, there are some devices on the market that do not reach one meter, while other devices may reach up to several meters. There are also devices that do not tolerate extreme closeness, the typical sweet spot for IrDA communications is from 5 to 60 cm away from a transceiver, in the center of the cone. The two devices that communicate simulate full-duplex communication by quickly turning the link around, the primary device controls the timing of the link, but both sides are bound to certain hard constraints and are encouraged to turn the link around as fast as possible. The mandatory IrLAP is the layer of the IrDA specifications. It lies on top of the IrPHY layer and below the IrLMP layer and it represents the data link layer of the OSI model. The primary device controls the secondary devices, only if the primary device requests a secondary device to send, is it allowed to do so. The mandatory IrLMP is the layer of the IrDA specifications. It can be broken down into two parts, first, the LM-MUX, which lies on top of the IrLAP layer. The optional Tiny TP lies on top of the IrLMP layer and it provides, Transportation of large messages by SAR Flow control by giving credits to every logical channel The optional IrCOMM lets the infrared device act like either a serial or parallel port

Kernel (operating system)
–
The kernel is a computer program that is the core of a computers operating system, with complete control over everything in the system. It is the first program loaded on start-up and it handles the rest of start-up as well as input/output requests from software, translating them into data-processing instructions for the central processing unit. It handles memory and peripherals like keyboards, monitors, printers, the critical code of the kernel is usually loaded into a protected area of memory, which prevents it from being overwritten by applications or other, more minor parts of the operating system. The kernel performs its tasks, such as running processes and handling interrupts, in contrast, everything a user does is in user space, writing text in a text editor, running programs in a GUI, etc. This separation prevents user data and kernel data from interfering with other and causing instability. The kernels interface is an abstraction layer. When a process makes requests of the kernel, it is called a system call, Kernel designs differ in how they manage these system calls and resources. A monolithic kernel runs all the operating instructions in the same address space. A microkernel runs most processes in space, for modularity. The kernel takes responsibility for deciding at any time which of the running programs should be allocated to the processor or processors. Random-access memory Random-access memory is used to both program instructions and data. Typically, both need to be present in memory in order for a program to execute, often multiple programs will want access to memory, frequently demanding more memory than the computer has available. The kernel is responsible for deciding which memory each process can use, input/output devices I/O devices include such peripherals as keyboards, mice, disk drives, printers, network adapters, and display devices. The kernel allocates requests from applications to perform I/O to an appropriate device, key aspects necessary in resource management are the definition of an execution domain and the protection mechanism used to mediate the accesses to the resources within a domain. Kernels also usually provide methods for synchronization and communication between processes called inter-process communication, finally, a kernel must provide running programs with a method to make requests to access these facilities. The kernel has full access to the memory and must allow processes to safely access this memory as they require it. Often the first step in doing this is virtual addressing, usually achieved by paging and/or segmentation, virtual addressing allows the kernel to make a given physical address appear to be another address, the virtual address. This allows every program to behave as if it is the one running

Calendar
–
A calendar is a system of organizing days for social, religious, commercial or administrative purposes. This is done by giving names to periods of time, typically days, weeks, months, a date is the designation of a single, specific day within such a system. A calendar is also a record of such a system. A calendar can also mean a list of planned events, such as a calendar or a partly or fully chronological list of documents. Periods in a calendar are usually, though not necessarily, synchronized with the cycle of the sun or the moon. The most common type of calendar was the lunisolar calendar. Latin calendarium meant account book, register, the Latin term was adopted in Old French as calendier and from there in Middle English as calender by the 13th century. The course of the Sun and the Moon are the most evident forms of timekeeping, nevertheless, the Roman calendar contained very ancient remnants of a pre-Etruscan 10-month solar year. The first recorded calendars date to the Bronze Age, dependent on the development of writing in the Ancient Near East, a larger number of calendar systems of the Ancient Near East becomes accessible in the Iron Age, based on the Babylonian calendar. This includes the calendar of the Persian Empire, which in turn gave rise to the Zoroastrian calendar as well as the Hebrew calendar, calendars in antiquity were lunisolar, depending on the introduction of intercalary months to align the solar and the lunar years. This was mostly based on observation, but there may have been attempts to model the pattern of intercalation algorithmically. The Roman calendar was reformed by Julius Caesar in 45 BC, the Julian calendar was no longer dependent on the observation of the new moon but simply followed an algorithm of introducing a leap day every four years. This created a dissociation of the month from the lunation. The Islamic calendar is based on the prohibition of intercalation by Muhammad and this resulted in an observationally based lunar calendar that shifts relative to the seasons of the solar year. The first calendar reform of the modern era was the Gregorian calendar. Such ideas are mooted from time to time but have failed to gain traction because of the loss of continuity, massive upheaval in implementation, a full calendar system has a different calendar date for every day. Thus the week cycle is by not a full calendar system. The simplest calendar system just counts time periods from a reference date and this applies for the Julian day or Unix Time

Spreadsheet
–
A spreadsheet is an interactive computer application for organization, analysis and storage of data in tabular form. Spreadsheets are developed as computerized simulations of paper accounting worksheets, the program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate, a spreadsheet may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values and this makes the spreadsheet useful for what-if analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets, and can display either as text and numerals. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for financial and statistical operations. Such calculations as net present value or standard deviation can be applied to data with a pre-programmed function in a formula. Spreadsheet programs also provide conditional expressions, functions to convert between text and numbers, and functions operate on strings of text. Spreadsheets have replaced paper-based systems throughout the business world, although they were first developed for accounting or bookkeeping tasks, they now are used extensively in any context where tabular lists are built, sorted, and shared. LANPAR, available in 1969, was the first electronic spreadsheet on mainframe and time sharing computers, LANPAR was an acronym, LANguage for Programming Arrays at Random. VisiCalc was the first electronic spreadsheet on a microcomputer, and it helped turn the Apple II computer into a popular, Lotus 1-2-3 was the leading spreadsheet when DOS was the dominant operating system. Excel now has the largest market share on the Windows and Macintosh platforms, a spreadsheet program is a standard feature of an office productivity suite, since the advent of web apps, office suites now also exist in web app form. A spreadsheet consists of a table of cells arranged into rows and columns, X locations, the columns, are normally represented by letters, A, B, C, etc. while rows are normally represented by numbers,1,2,3, etc. A single cell can be referred to by addressing its row and column and this electronic concept of cell references was first introduced in LANPAR and a variant used in VisiCalc, and known as A1 notation. Additionally, spreadsheets have the concept of a range, a group of cells, for instance, one can refer to the first ten cells in the first column with the range A1, A10. LANPAR innovated forward referencing/natural order calculation which didnt re-appear until Lotus 123, in modern spreadsheet applications, several spreadsheets, often known as worksheets or simply sheets, are gathered together to form a workbook. A workbook is physically represented by a file, containing all the data for the book, the sheets, worksheets are normally represented by tabs that flip between pages, each one containing one of the sheets, although Numbers changes this model significantly. Cells in a multi-sheet book add the name to their reference, for instance

Internet
–
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, the primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Although the Internet was widely used by academia since the 1980s, Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the two decades since then, Internet use has grown 100-times, measured for the period of one year, newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The entertainment industry was initially the fastest growing segment on the Internet, the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking. Business-to-business and financial services on the Internet affect supply chains across entire industries, the Internet has no centralized governance in either technological implementation or policies for access and usage, each constituent network sets its own policies. The term Internet, when used to refer to the global system of interconnected Internet Protocol networks, is a proper noun. In common use and the media, it is not capitalized. Some guides specify that the word should be capitalized when used as a noun, the Internet is also often referred to as the Net, as a short form of network. Historically, as early as 1849, the word internetted was used uncapitalized as an adjective, the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are often used interchangeably in everyday speech, however, the World Wide Web or the Web is only one of a large number of Internet services. The Web is a collection of interconnected documents and other web resources, linked by hyperlinks, the term Interweb is a portmanteau of Internet and World Wide Web typically used sarcastically to parody a technically unsavvy user. The ARPANET project led to the development of protocols for internetworking, the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department. In an early sign of growth, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks, early international collaborations on the ARPANET were rare. European developers were concerned with developing the X.25 networks, in December 1974, RFC675, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand for internetworking and later RFCs repeated this use. Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network, in 1982, the Internet Protocol Suite was standardized, which permitted worldwide proliferation of interconnected networks.5 Mbit/s and 45 Mbit/s. Commercial Internet service providers emerged in the late 1980s and early 1990s, the ARPANET was decommissioned in 1990

Java Platform, Micro Edition
–
Java Platform, Micro Edition or Java ME is a computing platform for development and deployment of portable code for embedded and mobile devices. Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME, the platform uses the object-oriented Java programming language. It is part of the Java software-platform family, Java ME was designed by Sun Microsystems, acquired by Oracle Corporation in 2010, the platform replaced a similar technology, PersonalJava. Originally developed under the Java Community Process as JSR68, the different flavors of Java ME have evolved in separate JSRs, as of 22 December 2006, the Java ME source code is licensed under the GNU General Public License, and is released under the project name phoneME. As of 2008, all Java ME platforms are currently restricted to JRE1.3 features, Java ME devices implement a profile. Profiles are subsets of configurations, of which there are two, the Connected Limited Device Configuration and the Connected Device Configuration. There are more than 2.1 billion Java ME enabled mobile phones and it is popular in sub $200 devices such as Nokias Series 40. It was also used on the Bada operating system and on Symbian OS along with native software, users of Windows CE, Windows Mobile, Maemo, MeeGo and Android can download Java ME for their respective environments. The Connected Limited Device Configuration contains a subset of the Java-class libraries. CLDC is basically used for classifying myriad devices into a fixed configuration, a configuration provides the most basic set of libraries and virtual-machine features that must be present in each implementation of a J2ME environment. When coupled with one or more profiles, the Connected Limited Device Configuration gives developers a solid Java platform for creating applications for consumer and embedded devices. The configuration is designed for devices with 160KB to 512KB total memory, designed for mobile phones, the Mobile Information Device Profile includes a GUI, and a data storage API, and MIDP2.0 includes a basic 2D gaming API. Applications written for this profile are called MIDlets, almost all new cell phones come with a MIDP implementation, and it is now the de facto standard for downloadable cell phone games. However, many cellphones can run only those MIDlets that have approved by the carrier. A key design goal of MIDP3 is backward compatibility with MIDP2 content, the Connected Device Configuration is a subset of Java SE, containing almost all the libraries that are not GUI related. The Foundation Profile is a Java ME Connected Device Configuration profile and this profile is intended to be used by devices requiring a complete implementation of the Java virtual machine up to and including the entire Java Platform, Standard Edition API. Typical implementations will use some subset of that API set depending on the additional profiles supported and this specification was developed under the Java Community Process. The Personal Basis Profile extends the Foundation Profile to include lightweight GUI support in the form of an AWT subset and this is the platform that BD-J is built upon

DotGNU
–
DotGNU is a decommissioned part of the GNU Project that aims to provide a free software replacement for Microsofts. NET Framework by Free Software Foundation. Other goals of the project are better support for non-Windows platforms, the main goal of the DotGNU project code base was to provide a class library that is 100% Common Language Specification compliant. Portable. NET claims to support various instruction set architectures including x86, PPC, ARM, DotGNU Execution Environment is a web service server. It implements an intermediate based on three-address code, in which variables are kept in static single assignment form. LibJIT has also some use in other open source projects, including ILDJIT. The Portable. NET class library seeks to provide facilities for application development and these are primarily written in C#, but because of the Common Language Specification they can be used by any. NET language. Like. NET, the library is structured into Namespaces and Assemblies. It has additional top-level namespaces including Accessibility and DotGNU, in a typical operation, the Portable. NET compiler generates a Common Language Specification image, as specified in chapter 6 of ECMA-335, and the Portable. NET runtime takes this image and runs it. DotGNU points out that it is Free Software, and it sets out to ensure all aspects of DotGNU minimize dependence on proprietary components. DotGNU was one of the High Priority Free Software Projects from July 31,2007 till October 2,2008. DotGNU’s implementation of components of the. NET stack not submitted to the ECMA for standardization has been the source of patent violation concerns for much of the life of the project. In particular, discussion has taken place about whether Microsoft could destroy the DotGNU project through patent suits, the base technologies submitted to the ECMA may be non-problematic. These technologies are not fully implemented in DotGNU and are not required for developing DotGNU-applications

Free software
–
The right to study and modify software entails availability of the software source code to its users. This right is conditional on the person actually having a copy of the software. Richard Stallman used the existing term free software when he launched the GNU Project—a collaborative effort to create a freedom-respecting operating system—and the Free Software Foundation. The FSFs Free Software Definition states that users of software are free because they do not need to ask for permission to use the software. Free software thus differs from proprietary software, such as Microsoft Office, Google Docs, Sheets, and Slides or iWork from Apple, which users cannot study, change, freeware, which is a category of freedom-restricting proprietary software that does not require payment for use. For computer programs that are covered by law, software freedom is achieved with a software license. Software that is not covered by law, such as software in the public domain, is free if the source code is in the public domain. Proprietary software, including freeware, use restrictive software licences or EULAs, Users are thus prevented from changing the software, and this results in the user relying on the publisher to provide updates, help, and support. This situation is called vendor lock-in, Users often may not reverse engineer, modify, or redistribute proprietary software. Other legal and technical aspects, such as patents and digital rights management may restrict users in exercising their rights. Free software may be developed collaboratively by volunteer computer programmers or by corporations, as part of a commercial, from the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which was typically public domain software. Software was commonly shared by individuals who used computers and by manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, SHARE, were formed to exchange of software. As software was written in an interpreted language such as BASIC. Software was also shared and distributed as printed source code in computer magazines and books, in United States vs. IBM, filed January 17,1969, the government charged that bundled software was anti-competitive. While some software might always be free, there would henceforth be an amount of software produced primarily for sale. In the 1970s and early 1980s, the industry began using technical measures to prevent computer users from being able to study or adapt the software as they saw fit. In 1980, copyright law was extended to computer programs, Software development for the GNU operating system began in January 1984, and the Free Software Foundation was founded in October 1985

Karnataka
–
Karnataka is a state in south western region of India. It was formed on 1 November 1956, with the passage of the States Reorganisation Act, originally known as the State of Mysore, it was renamed Karnataka in 1973. The capital and largest city is Bangalore, the state covers an area of 191,976 square kilometres, or 5.83 percent of the total geographical area of India. It is the seventh largest Indian state by area, with 61,130,704 inhabitants at the 2011 census, Karnataka is the eighth largest state by population, comprising 30 districts. Kannada, one of the languages of India, is the most widely spoken. Most of these rivers flow out of Karnataka eastward into the Bay of Bengal, though several etymologies have been suggested for the name Karnataka, the generally accepted one is that Karnataka is derived from the Kannada words karu and nādu, meaning elevated land. Karu nadu may also be read as karu, meaning black, the British used the word Carnatic, sometimes Karnatak, to describe both sides of peninsular India, south of the Krishna. With an antiquity that dates to the paleolithic, Karnataka has been home to some of the most powerful empires of ancient, the philosophers and musical bards patronised by these empires launched socio-religious and literary movements which have endured to the present day. Karnataka has contributed significantly to both forms of Indian classical music, the Carnatic and Hindustani traditions, Karnatakas pre-history goes back to a paleolithic hand-axe culture evidenced by discoveries of, among other things, hand axes and cleavers in the region. Evidence of neolithic and megalithic cultures have also found in the state. Gold discovered in Harappa was found to be imported from mines in Karnataka, prior to the third century BCE, most of Karnataka formed part of the Nanda Empire before coming under the Mauryan empire of Emperor Ashoka. Four centuries of Satavahana rule followed, allowing them to large areas of Karnataka. The decline of Satavahana power led to the rise of the earliest native kingdoms, the Kadambas, the Kadamba Dynasty, founded by Mayurasharma, had its capital at Banavasi, the Western Ganga Dynasty was formed with Talakad as its capital. These were also the first kingdoms to use Kannada in administration, as evidenced by the Halmidi inscription, the Western Chalukyas patronised a unique style of architecture and Kannada literature which became a precursor to the Hoysala art of 12th century. Parts of modern-day Southern Karnataka were occupied by the Chola Empire at the turn of 11th century, the Cholas and the Hoysalas fought over the region in the early 12th century before it eventually came under Hoysala rule. At the turn of the first millennium, the Hoysalas gained power in the region, literature flourished during this time, which led to the emergence of distinctive Kannada literary metres, and the construction of temples and sculptures adhering to the Vesara style of architecture. The expansion of the Hoysala Empire brought minor parts of modern Andhra Pradesh, in the early 14th century, Harihara and Bukka Raya established the Vijayanagara empire with its capital, Hosapattana, on the banks of the Tungabhadra River in the modern Bellary district. The empire rose as a bulwark against Muslim advances into South India, in 1565, Karnataka and the rest of South India experienced a major geopolitical shift when the Vijayanagara empire fell to a confederation of Islamic sultanates in the Battle of Talikota

Chhattisgarh is one of 29 states located in central India. It is the 10th largest state in India, with an area of 135,194 km2, with a population of 28 million, Chhattisgarh is the 17th most-populated state in the country. A resource-rich state, it is a source of electricity and steel for the country, Chhattisgarh is one of the fastest-developing states in India. The state was formed on 1 November 2000 by partitioning 16 Chhattisgarhi-speaking southeastern districts of Madhya Pradesh, currently the state comprises 27 districts. The following are the list of the districts of Chhattisgarh State, There are several opinions as to the origin of the name Chhattisgarh, Chhattisgarh was popularized later during the time of the Maratha Empire and was first used in an official document in 1795. It is claimed that Chhattisgarh takes its name from the 36 ancient forts in the area, however, experts do not agree with this explanation, as 36 forts cannot be archaeologically identified in this region. Another view, more popular with experts and historians, is that Chhattisgarh is the form of Chedisgarh which means Raj or Empire of the Chedis. In ancient times, Chhattisgarh region had been part of the Chedi dynasty of Kaling, in the medieval period up to 1803, a major portion of present eastern Chhattisgarh was part of the Sambalpur Kingdom of Odisha. The northern and southern parts of the state are hilly, while the part is a fertile plain. The highest point in the state is the Bailadila Range, deciduous forests of the Eastern Highlands Forests cover roughly 44% of the state. The state animal is the van bhainsa, or wild water buffalo, the state bird is the pahari myna, or hill myna. The state tree is the Sal found in Bastar division, in the north lies the edge of the great Indo-Gangetic plain. The Rihand River, a tributary of the Ganges, drains this area, the eastern end of the Satpura Range and the western edge of the Chota Nagpur Plateau form an east-west belt of hills that divide the Mahanadi River basin from the Indo-Gangetic plain. The outline of Chhattisgarh is like a sea horse, the central part of the state lies in the fertile upper basin of the Mahanadi river and its tributaries. This area has extensive rice cultivation, the upper Mahanadi basin is separated from the upper Narmada basin to the west by the Maikal Hills and from the plains of Odisha to the east by ranges of hills. The southern part of the lies on the Deccan plateau, in the watershed of the Godavari River and its tributary. The Mahanadi is the river of the state.

Car
–
A car is a wheeled, self-powered motor vehicle used for transportation and a product of the automotive industry. The year 1886 is regarded as the year of the modern car. In that year, German inventor Karl Benz built the Benz Patent-Motorwagen, cars did not become widely available until the early 20th century. One of the first cars that was accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the United States of America, where they replaced animal-drawn carriages and carts, cars are equipped with controls used for driving, parking, passenger comfort and safety, and controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, examples include rear reversing cameras, air conditioning, navigation systems, and in car entertainment. Most cars in use in the 2010s are propelled by a combustion engine. Both fuels cause air pollution and are blamed for contributing to climate change. Vehicles using alternative fuels such as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some countries, electric cars, which were invented early in the history of the car, began to become commercially available in 2008. There are costs and benefits to car use, the costs of car usage include the cost of, acquiring the vehicle, interest payments, repairs and auto maintenance, fuel, depreciation, driving time, parking fees, taxes, and insurance. The costs to society of car use include, maintaining roads, land use, road congestion, air pollution, public health, health care, road traffic accidents are the largest cause of injury-related deaths worldwide. The benefits may include transportation, mobility, independence. The ability for humans to move flexibly from place to place has far-reaching implications for the nature of societies and it was estimated in 2010 that the number of cars had risen to over 1 billion vehicles, up from the 500 million of 1986. The numbers are increasing rapidly, especially in China, India, the word car is believed to originate from the Latin word carrus or carrum, or the Middle English word carre. In turn, these originated from the Gaulish word karros, the Gaulish language was a branch of the Brythoic language which also used the word Karr, the Brythonig language evolved into Welsh where Car llusg and car rhyfel still survive. It originally referred to any wheeled vehicle, such as a cart, carriage. Motor car is attested from 1895, and is the formal name for cars in British English. Autocar is a variant that is attested from 1895

Engine
–
An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines burn a fuel to heat, which is then used to create a force. Electric motors convert electrical energy into motion, pneumatic motors use compressed air. In biological systems, molecular motors, like myosins in muscles, use energy to create forces. The word engine derives from Old French engin, from the Latin ingenium–the root of the word ingenious. Pre-industrial weapons of war, such as catapults, trebuchets and battering rams, were called siege engines, the word gin, as in cotton gin, is short for engine. Most mechanical devices invented during the revolution were described as engines—the steam engine being a notable example. However, the steam engines, such as those by Thomas Savery, were not mechanical engines. In this manner, an engine in its original form was merely a water pump. Devices converting heat energy into motion are commonly referred to simply as engines, examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets, the term motor derives from the Latin verb moto which means to set in motion, or maintain motion. Thus a motor is a device that imparts motion, motor and engine later came to be used largely interchangeably in casual discourse. However, technically, the two words have different meanings, however, rocketry uses the term rocket motor, even though they consume fuel. A heat engine may also serve as a prime mover—a component that transforms the flow or changes in pressure of a fluid into mechanical energy. An automobile powered by a combustion engine may make use of various motors and pumps. Another way of looking at it is that a motor receives power from an external source, simple machines, such as the club and oar, are prehistoric. More complex engines using human power, animal power, water power, wind power and these were used in cranes and aboard ships in Ancient Greece, as well as in mines, water pumps and siege engines in Ancient Rome. The writers of those times, including Vitruvius, Frontinus and Pliny the Elder, treat these engines as commonplace, by the 1st century AD, cattle and horses were used in mills, driving machines similar to those powered by humans in earlier times

It is also the wealthiest city in India, and has the highest GDP of any city in South, West, Mumbai has the highest number of billionaires and millionaires among all cities in India. The seven islands that came to constitute Mumbai were home to communities of fishing colonies, during the mid-18th century, Bombay was reshaped by the Hornby Vellard project, which undertook reclamation of the area between the seven islands from the sea. Along with construction of roads and railways, the reclamation project, completed in 1845. Bombay in the 19th century was characterised by economic and educational development, during the early 20th century it became a strong base for the Indian independence movement. Upon Indias independence in 1947 the city was incorporated into Bombay State, in 1960, following the Samyukta Maharashtra movement, a new state of Maharashtra was created with Bombay as the capital. Mumbai is the financial, commercial and entertainment capital of India and it is also home to some of Indias premier scientific and nuclear institutes like BARC, NPCL, IREL, TIFR, AERB, AECI, and the Department of Atomic Energy. The city also houses Indias Hindi and Marathi film and television industry, Mumbais business opportunities, as well as its potential to offer a higher standard of living, attract migrants from all over India, making the city a melting pot of many communities and cultures. The oldest known names for the city are Kakamuchee and Galajunkja, in 1508, Portuguese writer Gaspar Correia used the name Bombaim, in his Lendas da Índia. This name possibly originated as the Old Portuguese phrase bom baim, meaning good little bay, in 1516, Portuguese explorer Duarte Barbosa used the name Tana-Maiambu, Tana appears to refer to the adjoining town of Thane and Maiambu to Mumbadevi. Other variations recorded in the 16th and the 17th centuries include, Mombayn, Bombay, Bombain, Bombaym, Monbaym, Mombaim, Mombaym, Bambaye, Bombaiim, Bombeye, Boon Bay, and Bon Bahia. After the English gained possession of the city in the 17th century, Ali Muhammad Khan, imperial diwan or revenue minister of the Gujarat province, in the Mirat-i-Ahmedi referred to the city as Manbai. By the late 20th century, the city was referred to as Mumbai or Mambai in the Indian statewise official languages of Marathi, Konkani, Gujarati, Kannada and Sindhi, the Government of India officially changed the English name to Mumbai in November 1995. According to Slate magazine, they argued that Bombay was a corrupted English version of Mumbai, Slate also said The push to rename Bombay was part of a larger movement to strengthen Marathi identity in the Maharashtra region. A resident of Mumbai is called mumbaikar in the Marathi language, the term has been in use for quite some time but it gained popularity after the official name change to Mumbai. Mumbai is built on what was once an archipelago of seven islands, Bombay Island, Parel, Mazagaon, Mahim, Colaba, Worli and it is not exactly known when these islands were first inhabited

Mining
–
Mining is extraction of valuable minerals or other geological materials from the earth usually from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner, ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times, Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines, levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products, due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves. Since the beginning of civilization, people have used stone, ceramics and, later and these were used to make early tools and weapons, for example, high quality flint found in northern France, southern England and Poland was used to create flint tools. Flint mines have been found in areas where seams of the stone were followed underground by shafts. The mines at Grimes Graves and Krzemionki are especially famous, other hard rocks mined or collected for axes included the greenstone of the Langdale axe industry based in the English Lake District. The oldest-known mine on archaeological record is the Lion Cave in Swaziland, at this site Paleolithic humans mined hematite to make the red pigment ochre. Mines of an age in Hungary are believed to be sites where Neanderthals may have mined flint for weapons. Ancient Egyptians mined malachite at Maadi, at first, Egyptians used the bright green malachite stones for ornamentations and pottery. Later, between 2613 and 2494 BC, large building projects required expeditions abroad to the area of Wadi Maghareh in order to secure minerals and other resources not available in Egypt itself. Quarries for turquoise and copper were found at Wadi Hammamat, Tura, Aswan and various other Nubian sites on the Sinai Peninsula. Mining in Egypt occurred in the earliest dynasties, the gold mines of Nubia were among the largest and most extensive of any in Ancient Egypt. These mines are described by the Greek author Diodorus Siculus, who mentions fire-setting as one used to break down the hard rock holding the gold. One of the complexes is shown in one of the earliest known maps, the miners crushed the ore and ground it to a fine powder before washing the powder for the gold dust

Goa /ˈɡoʊ. ə/ is a state in India within the coastal region known as the Konkan in western India. It is bounded by Maharashtra to the north and Karnataka to the east and it is Indias smallest state by area and the fourth smallest by population. Goa is Indias richest state, with a GDP per capita two and a half times that of the country, Panaji is the states capital, while Vasco da Gama is its largest city. The historic city of Margao still exhibits the influence of the Portuguese. Goa is a former Portuguese province, the Portuguese overseas territory of Portuguese India existed for about 450 years until it was annexed by India in 1961. Goa is visited by large numbers of international and domestic tourists each year for its beaches, places of worship and it has rich flora and fauna, owing to its location on the Western Ghats range, a biodiversity hotspot. In ancient literature, Goa was known by names, such as Gomanchala, Gopakapattana, Gopakapattam, Gopakapuri, Govapuri, Govem. In the 3rd century BC, Goa was known as Aparantha and is mentioned by the Greek geographer Ptolemy, in the 13th century, the Greeks referred to Goa as Nelkinda. Other historical names for Goa are Sindapur, Sandabur, and Mahassapatam, Goas history goes back 20, 000–30,000 years. The rock art engravings exhibit the earliest traces of life in India. Upper Paleolithic or Mesolithic rock art engravings have been found on the bank of the river Kushavati at Usgalimal. Petroglyphs, cones, stone-axe, and choppers dating to 10,000 years ago have been found in places in Goa, such as Kazur, Mauxim. Evidence of Palaeolithic life is seen at Dabolim, Adkon, Shigao, Fatorpa, Arli, Maulinguinim, Diwar, Sanguem, Pilerne, difficulty in carbon dating the laterite rock compounds poses a problem for determining the exact time period. Early Goan society underwent radical change when Indo-Aryan and Dravidian migrants amalgamated with the aboriginal locals, in the 3rd century BC, Goa was part of the Maurya Empire, ruled by the Buddhist emperor, Ashoka of Magadha. Buddhist monks laid the foundation of Buddhism in Goa, between the 2nd century BC and the 6th century AD, Goa was ruled by the Bhojas of Goa. The rule later passed to the Chalukyas of Badami, who controlled it between 578 and 753, and later the Rashtrakutas of Malkhed from 753 to 963, from 765 to 1015, the Southern Silharas of Konkan ruled Goa as the feudatories of the Chalukyas and the Rashtrakutas. Over the next few centuries, Goa was successively ruled by the Kadambas as the feudatories of the Chalukyas of Kalyani, in 1312, Goa came under the governance of the Delhi Sultanate. The kingdoms grip on the region was weak, and by 1370 it was forced to surrender it to Harihara I of the Vijayanagara empire, the Vijayanagara monarchs held on to the territory until 1469, when it was appropriated by the Bahmani sultans of Gulbarga

Microcredit
–
This article is specific to small loans, often provided in a pooled manner. For direct payments to individuals for specific projects, see Micropatronage, for financial services to the poor, see Microfinance. Microcredit is the extension of small loans to impoverished borrowers who typically lack collateral, steady employment. It is designed not only to support entrepreneurship and alleviate poverty, in many communities, women lack the highly stable employment histories that traditional lenders tend to require. Many are illiterate, and therefore unable to complete paperwork required to get conventional loans, as of 2009 an estimated 74 million men and women held microloans that totalled US$38 billion. Grameen Bank reports that repayment success rates are between 95 and 98 percent, Microcredit is part of microfinance, which provides a wider range of financial services, especially savings accounts, to the poor. Modern microcredit is generally considered to have originated with the Grameen Bank founded in Bangladesh in 1983, many traditional banks subsequently introduced microcredit despite initial misgivings. The United Nations declared 2005 the International Year of Microcredit, as of 2012, microcredit is widely used in developing countries and is presented as having enormous potential as a tool for poverty alleviation. Ideas relating to microcredit can be found at times in modern history. Jonathan Swift inspired the Irish Loan Funds of the 18th and 19th centuries, in the mid-19th century, Individualist anarchist Lysander Spooner wrote about the benefits of numerous small loans for entrepreneurial activities to the poor as a way to alleviate poverty. At about the time, but independently to Spooner, Friedrich Wilhelm Raiffeisen founded the first cooperative lending banks to support farmers in rural Germany. In the 1950s, Akhtar Hameed Khan began distributing group-oriented credit in East Pakistan, Khan used the Comilla Model, in which credit is distributed through community-based initiatives. The project failed due to the over-involvement of the Pakistani government, the origins of microcredit in its current practical incarnation can be linked to several organizations founded in Bangladesh, especially the Grameen Bank. The Grameen Bank, which is considered the first modern microcredit institution, was founded in 1983 by Muhammad Yunus. Yunus began the project in a town called Jobra, using his own money to deliver small loans at low-interest rates to the rural poor. Grameen Bank was followed by such as BRAC in 1972. Microcredit reached Latin America with the establishment of PRODEM in Bolivia in 1986, Microcredit quickly became a popular tool for economic development, with hundreds of institutions emerging throughout the third world. Though the Grameen Bank was formed initially as a non-profit organization dependent upon government subsidies, Muhammad Yunus was awarded the Nobel Peace Prize in 2006 for his work providing microcredit services to the poor

Ghana, officially the Republic of Ghana, is a unitary presidential constitutional democracy, located along the Gulf of Guinea and Atlantic Ocean, in the subregion of West Africa. Spanning a land mass of 238,535 km², Ghana is bordered by the Ivory Coast in the west, Burkina Faso in the north, Togo in the east, Ghana means Warrior King in the Soninke language. The territory of present-day Ghana has been inhabited for a millennium, numerous kingdoms and empires emerged over the centuries, of which the most powerful was the Kingdom of Ashanti. Beginning in the 15th century, numerous European powers contested the area for trading rights, following over a century of native resistance, Ghanas current borders were established by the 1900s as the British Gold Coast. On 6 March 1957, it became the first sub-Saharan African nation to become independent of European colonisation, a multicultural nation, Ghana has a population of approximately 27 million, spanning a variety of ethnic, linguistic and religious groups. Five percent of the population practices traditional faiths,71. 2% adhere to Christianity and 17. 6% are Muslim and its diverse geography and ecology ranges from coastal savannahs to tropical jungles. Ghana is a country led by a president who is both head of state and head of the government. Ghanas economy is one of the strongest and most diversified in Africa, following a century of relative stability. Ghanas growing economic prosperity and democratic political system have made it a power in West Africa. It is a member of the Non-Aligned Movement, the African Union, the Economic Community of West African States, Group of 24, Ghana was already recognized as one of the great kingdoms in Bilad el-Sudan by the ninth century. Ghana was inhabited in the Middle Ages and the Age of Discovery by a number of ancient predominantly Akan kingdoms in the Southern and this included the Ashanti Empire, the Akwamu, the Bonoman, the Denkyira, and the Mankessim Kingdom. Until the 11th century, the majority of modern Ghanas territorial area was unoccupied and uninhabited by humans. Although the area of present-day Ghana in West Africa has experienced many population movements, by the early 11th century, the Akans were firmly established in the Akan state called Bonoman, for which the Brong-Ahafo Region is named. From the 13th century, Akans emerged from what is believed to have been the Bonoman area, to create several Akan states of Ghana and these states included Bonoman, Ashanti, Denkyira, Mankessim Kingdom, and Akwamu Eastern region. By the 19th century, the territory of the part of Ghana was included in the Kingdom of Ashanti.

Many newspapers and broadcasters outside the United States are AP subscribers, as part of their cooperative agreement with the AP, most member news organizations grant automatic permission for the AP to distribute their local news reports. The AP employs the inverted pyramid formula for writing that enables the news outlets to edit a story to fit its available publication area without losing the storys essentials. Cutbacks at rival United Press International in 1993 left the AP as the United States primary news service, although UPI still produces and distributes stories and photos daily. Other English-language news services, such as the BBC, Reuters, some historians believe that the Tribune joined at this time, documents show it was a member in 1849. The New York Times became a member shortly after its founding in September 1851, initially known as the New York Associated Press, the organization faced competition from the Western Associated Press, which criticized its monopolistic news gathering and price setting practices. The revelations led to the demise of the NYAP and in December 1892, when the AP was founded, news became a salable commodity. The invention of the press allowed the New York Tribune in the 1870s to print 18,000 papers per hour. During the Civil War and Spanish–American War, there was a new incentive to print vivid, Melville Stone, who had founded the Chicago Daily News in 1875, served as AP General Manager from 1893 to 1921. He embraced the standards of accuracy, impartiality, and integrity, the cooperative grew rapidly under the leadership of Kent Cooper, who built up bureau staff in South America, Europe and, the Middle East. He introduced the telegraph typewriter or teletypewriter into newsrooms in 1914, in 1935, AP launched the Wirephoto network, which allowed transmission of news photographs over leased private telephone lines on the day they were taken. This gave AP a major advantage over other media outlets. While the first network was only between New York, Chicago, and San Francisco, eventually AP had its network across the whole United States, in 1945, the Supreme Court of the United States held in Associated Press v. The decision facilitated the growth of its main rival United Press International, AP entered the broadcast field in 1941 when it began distributing news to radio stations, it created its own radio network in 1974

DMOZ was a multilingual open-content directory of World Wide Web links. The site and community who maintained it were known as the Open Directory Project. It was owned by AOL but constructed and maintained by a community of volunteer editors, DMOZ used a hierarchical ontology scheme for organizing site listings. Listings on a similar topic were grouped into categories which included smaller categories. It was announced on February 28,2017 that DMOZ would close down on March 14,2017, DMOZ was founded in the United States as Gnuhoo by Rich Skrenta and Bob Truel in 1998 while they were both working as engineers for Sun Microsystems. Skrenta had developed TASS, an ancestor of tin, the popular threaded Usenet newsreader for Unix systems, the original category structure of the Gnuhoo directory was based loosely on the structure of Usenet newsgroups then in existence. The Gnuhoo directory went live on June 5,1998, then objected to the use of Hoo in the name, prompting a proposed name change, to ZURL. Prior to switching to ZURL, NewHoo was acquired by Netscape Communications Corporation in October 1998, Netscape released Open Directory data under the Open Directory License. Netscape was acquired by AOL shortly thereafter and DMOZ was one of the assets included in the acquisition, by the time Netscape assumed stewardship, the Open Directory Project had about 100,000 URLs indexed with contributions from about 4500 editors. On October 5,1999, the number of URLs indexed by DMOZ reached one million, according to an unofficial estimate, the URLs in DMOZ numbered 1.6 million in April 2000, surpassing those in the Yahoo. DMOZ achieved the milestones of indexing two million URLs on August 14,2000, three million listings on November 18,2001 and four million on December 3,2003. As of April,2013 there were 5,169,995 sites listed in over 1,017,500 categories, on October 31,2015, there were 3,996,412 sites listed in 1,026,706 categories. In January 2006, DMOZ began publishing reports to inform the public about the development of the project. The first report covered the year 2005, monthly reports were issued subsequently until September 2006. These reports gave greater insight into the functioning of the directory than the statistics provided on the front page of the directory. The number of listings and categories cited on the front page included Test and Bookmarks categories, there were about 7330 active editors during August 2006. 75,151 editors had contributed to the directory as of March 31,2007, as of April 2013, the number of contributing editors had increased to 97,584. On October 20,2006, DMOZs main server suffered a failure that prevented editors from working on the directory until December 18,2006
