Unicode
–
Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the worlds writing systems. As of June 2016, the most recent version is Unicode 9.0, the standard is maintained by the Unicode Consortium. Unicodes success at unifying character sets has led to its widespread, the standard has been implemented in many recent technologies, including modern operating systems, XML, Java, and the. NET Framework. Unicode can be implemented by different character encodings, the most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit for each character but cannot encode every character in the current Unicode standard, UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units to handle each of the additional characters. Many traditional character encodings share a common problem in that they allow bilingual computer processing, Unicode, in intent, encodes the underlying characters—graphemes and grapheme-like units—rather than the variant glyphs for such characters. In the case of Chinese characters, this leads to controversies over distinguishing the underlying character from its variant glyphs. In text processing, Unicode takes the role of providing a unique code point—a number, in other words, Unicode represents a character in an abstract way and leaves the visual rendering to other software, such as a web browser or word processor. This simple aim becomes complicated, however, because of concessions made by Unicodes designers in the hope of encouraging a more rapid adoption of Unicode, the first 256 code points were made identical to the content of ISO-8859-1 so as to make it trivial to convert existing western text. For other examples, see duplicate characters in Unicode and he explained that he name Unicode is intended to suggest a unique, unified, universal encoding. In this document, entitled Unicode 88, Becker outlined a 16-bit character model, Unicode could be roughly described as wide-body ASCII that has been stretched to 16 bits to encompass the characters of all the worlds living languages. In a properly engineered design,16 bits per character are more than sufficient for this purpose, Unicode aims in the first instance at the characters published in modern text, whose number is undoubtedly far below 214 =16,384. By the end of 1990, most of the work on mapping existing character encoding standards had been completed, the Unicode Consortium was incorporated in California on January 3,1991, and in October 1991, the first volume of the Unicode standard was published. The second volume, covering Han ideographs, was published in June 1992, in 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. The Microsoft TrueType specification version 1.0 from 1992 used the name Apple Unicode instead of Unicode for the Platform ID in the naming table, Unicode defines a codespace of 1,114,112 code points in the range 0hex to 10FFFFhex. Normally a Unicode code point is referred to by writing U+ followed by its hexadecimal number, for code points in the Basic Multilingual Plane, four digits are used, for code points outside the BMP, five or six digits are used, as required. Code points in Planes 1 through 16 are accessed as surrogate pairs in UTF-16, within each plane, characters are allocated within named blocks of related characters

Multilingualism
–
Multilingualism is the use of two or more languages, either by an individual speaker or by a community of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the worlds population, more than half of all Europeans claim to speak at least one other language in addition to their mother tongue. Multilingualism is becoming a social phenomenon governed by the needs of globalization, people who speak several languages are also called polyglots. Multilingual speakers have acquired and maintained at least one language during childhood, the first language is acquired without formal education, by mechanisms heavily disputed. Children acquiring two languages in this way are called simultaneous bilinguals, even in the case of simultaneous bilinguals, one language usually dominates the other. People who know more than one language have been reported to be adept at language learning compared to monolinguals. Multilingualism in computing can be considered part of a continuum between internationalization and localization, the definition of multilingualism is a subject of debate in the very same way as the definition of language fluency. On one end of a sort of continuum, one may define multilingualism as complete competence. The speaker would presumably have complete knowledge and control over the language so as to sound native, on the opposite end of the spectrum would be people who know enough phrases to get around as a tourist using the alternate language. Since 1992, Vivian Cook has argued that most multilingual speakers fall somewhere between minimal and maximal definitions, in addition, there is no consistent definition of what constitutes a distinct language. For instance, scholars disagree whether Scots is a language in its own right or a dialect of English. Many small independent nations schoolchildren are today compelled to learn multiple languages because of international interactions, for example, in, all children are required to learn at least two foreign languages, the other national language and one alien language. Many Finnish schoolchildren also select further languages, such as German or Russian, in some large nations with multiple languages, such as India, school children may routinely learn multiple languages based on where they reside in the country. In major metropolitan areas of Central, South and East India, thus a child of Telugu parents living in Bangalore will end up speaking his or her mother tongue at home and the state language, Hindi and English in school and his or her surroundings. Many myths and much prejudice has grown around the notions of bi- and these are all harmful convictions which have long been debunked, yet still persist among many parents. A multilingual person is someone who can communicate in more than one language, more specifically, the terms bilingual and trilingual are used to describe comparable situations in which two or three languages are involved. A multilingual person is referred to as a polyglot. Multilingual speakers have acquired and maintained at least one language during childhood, the first language is acquired without formal education, by mechanisms heavily disputed

Internationalization and localization
–
In computing, internationalization and localization are means of adapting computer software to different languages, regional differences and technical requirements of a target market. Internationalization is the process of designing a software application so that it can potentially be adapted to various languages, localization is the process of adapting internationalized software for a specific region or language by adding locale-specific components and translating text. Localization uses the infrastructure or flexibility provided by internationalization, the terms are frequently abbreviated to the numeronyms i18n and L10n for localization, due to the length of the words. Some companies, like IBM and Sun Microsystems, use the term globalization, g11n, Microsoft defines Internationalization as a combination of World-Readiness and localization. World-Readiness is a task, which enables a product to be used with multiple scripts and cultures. Hewlett-Packard and HP-UX created the system called NLS to produce localizable software, translation is typically the most time-consuming component of language localization. These differences may need to be taken account by the internationalization process in preparation for translation. Many of these differences are so regular that a conversion between languages can be easily automated, the Common Locale Data Repository by Unicode provides a collection of such differences. Its data is used by operating systems, including Microsoft Windows, OS X and Debian, and by major internet companies or projects such as Google. Examples of such include, Different scripts in different writing systems use different characters - a different set of letters, syllograms, logograms. Modern system use the Unicode standard to represent many different languages with a character encoding. Writing direction is left to right in most European languages, right-to-left in Hebrew and Arabic, complex text layout, for languages where characters change shape depending on context. Capitalization exists in some scripts and not in others, other grammar rules might also vary, e. g. genitive. Keyboard shortcuts can only use of buttons actually on the keyboard layout which is being localized for. If a shortcut corresponds to a word in a particular language, other areas often follow one of these. Specific third-party services, such as maps, weather reports, or payment service providers, might not be available worldwide from the same carriers. Time zones vary across the world, and this must be taken into account if a product originally only interacted with people in a time zone. For internationalization, UTC is often used internally and then converted into a time zone for display purposes

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

XML
–
In computing, Extensible Markup Language is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The W3Cs XML1.0 Specification and several other related specifications—all of them free open standards—define XML, the design goals of XML emphasize simplicity, generality, and usability across the Internet. It is a data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is used for the representation of arbitrary data structures such as those used in web services. Several schema systems exist to aid in the definition of XML-based languages, hundreds of document formats using XML syntax have been developed, including RSS, Atom, SOAP, SVG, and XHTML. XML-based formats have become the default for many office-productivity tools, including Microsoft Office, OpenOffice. org and LibreOffice, XML has also provided the base language for communication protocols such as XMPP. Applications for the Microsoft. NET Framework use XML files for configuration, apple has an implementation of a registry based on XML. XML has come into use for the interchange of data over the Internet. IETF RFC7303 gives rules for the construction of Internet Media Types for use when sending XML and it also defines the media types application/xml and text/xml, which say only that the data is in XML, and nothing about its semantics. The use of text/xml has been criticized as a source of encoding problems. RFC7303 also recommends that XML-based languages be given media types ending in +xml, further guidelines for the use of XML in a networked context appear in RFC3470, also known as IETF BCP70, a document covering many aspects of designing and deploying an XML-based language. The material in this section is based on the XML Specification and this is not an exhaustive list of all the constructs that appear in XML, it provides an introduction to the key constructs most often encountered in day-to-day use. Character An XML document is a string of characters, almost every legal Unicode character may appear in an XML document. Processor and application The processor analyzes the markup and passes structured information to an application, the specification places requirements on what an XML processor must do and not do, but the application is outside its scope. The processor is often referred to colloquially as an XML parser, Markup and content The characters making up an XML document are divided into markup and content, which may be distinguished by the application of simple syntactic rules. Generally, strings that constitute markup either begin with the character < and end with a >, or they begin with the character &, strings of characters that are not markup are content. However, in a CDATA section, the delimiters <. > are classified as markup, in addition, whitespace before and after the outermost element is classified as markup. Tag A tag is a construct that begins with <

Java (programming language)
–
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere, Java applications are typically compiled to bytecode that can run on any Java virtual machine regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, Java was originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems Java platform. The language derives much of its syntax from C and C++, the original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licences. As of May 2007, in compliance with the specifications of the Java Community Process, others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java, GNU Classpath, and IcedTea-Web. James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991, Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. The language was initially called Oak after an oak tree that stood outside Goslings office, later the project went by the name Green and was finally renamed Java, from Java coffee. Gosling designed Java with a C/C++-style syntax that system and application programmers would find familiar, Sun Microsystems released the first public implementation as Java 1.0 in 1995. It promised Write Once, Run Anywhere, providing no-cost run-times on popular platforms, fairly secure and featuring configurable security, it allowed network- and file-access restrictions. Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular, while mostly outside of browsers, in January 2016, Oracle announced that Java runtime environments based on JDK9 will discontinue the browser plugin. The Java 1.0 compiler was re-written in Java by Arthur van Hoff to comply strictly with the Java 1.0 language specification, with the advent of Java 2, new versions had multiple configurations built for different types of platforms. J2EE included technologies and APIs for enterprise applications typically run in server environments, the desktop version was renamed J2SE. In 2006, for marketing purposes, Sun renamed new J2 versions as Java EE, Java ME, in 1997, Sun Microsystems approached the ISO/IEC JTC1 standards body and later the Ecma International to formalize Java, but it soon withdrew from the process. Java remains a de facto standard, controlled through the Java Community Process, at one time, Sun made most of its Java implementations available without charge, despite their proprietary software status. Sun generated revenue from Java through the selling of licenses for specialized products such as the Java Enterprise System, on November 13,2006, Sun released much of its Java virtual machine as free and open-source software, under the terms of the GNU General Public License. Suns vice-president Rich Green said that Suns ideal role with regard to Java was as an evangelist and this did not prevent Oracle from filing a lawsuit against Google shortly after that for using Java inside the Android SDK. Java software runs on everything from laptops to data centers, game consoles to scientific supercomputers, on April 2,2010, James Gosling resigned from Oracle. There were five primary goals in the creation of the Java language, It must be simple, object-oriented and it must be robust and secure

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

Adobe Systems Incorporated /əˈdoʊbiː/ is an American multinational computer software company. The company is headquartered in San Jose, California, United States, Adobe has historically focused upon the creation of multimedia and creativity software products, with a more recent foray towards rich Internet application software development. It is best known for Photoshop, an image editing software, Acrobat Reader, Adobe was founded in February 1982 by John Warnock and Charles Geschke, who established the company after leaving Xerox PARC in order to develop and sell the PostScript page description language. In 1985, Apple Computer licensed PostScript for use in its LaserWriter printers, as of 2015, Adobe Systems has about 13,500 employees, about 40% of whom work in San Jose. The name of the company, Adobe, comes from Adobe Creek in Los Altos, California, Adobes corporate logo features a stylized A and was designed by the wife of John Warnock, Marva Warnock, who is a graphic designer. Adobes first products after PostScript were digital fonts, which released in a proprietary format called Type 1. Apple subsequently developed a standard, TrueType, which provided full scalability and precise control of the pixel pattern created by the fonts outlines. In the mid-1980s, Adobe entered the software market with Illustrator. Illustrator, which grew from the firms in-house font-development software, helped popularize PostScript-enabled laser printers, Adobe Systems entered NASDAQ in 1986. Its revenue has grown from roughly $1 billion in 1999 to roughly $4 billion in 2012, Adobes fiscal years run from December to November. For example, the 2007 fiscal year ended on November 30,2007, in 1989, Adobe introduced what was to become its flagship product, a graphics editing program for the Macintosh called Photoshop. Stable and full-featured, Photoshop 1.0 was ably marketed by Adobe, in 1993, Adobe introduced PDF, the Portable Document Format, and its Adobe Acrobat and Reader software. PDF is now an International Standard, ISO 32000-1,2008, in December 1991, Adobe released Adobe Premiere, which Adobe rebranded as Adobe Premiere Pro in 2003. In 1992, Adobe acquired OCR Systems, Inc, in 1994, Adobe acquired Aldus and added PageMaker and After Effects to its product line later in the year, it also controls the TIFF file format. In 1995, Adobe added FrameMaker, the long-document DTP application, in 1996, Adobe Systems Inc added Ares Software Corp. In 2002, Adobe acquired Canadian company Accelio, on December 12,2005, Adobe acquired its main rival, Macromedia, in a stock swap valued at about $3. Adobe released Adobe Media Player in April 2008, on April 27, Adobe discontinued development and sales of its older HTML/web development software, GoLive in favor of Dreamweaver. Adobe offered a discount on Dreamweaver for GoLive users and supports those who still use GoLive with online tutorials, on June 1, Adobe launched Acrobat. com, a series of web applications geared for collaborative work

Apple is an American multinational technology company headquartered in Cupertino, California that designs, develops, and sells consumer electronics, computer software, and online services. Apples consumer software includes the macOS and iOS operating systems, the media player, the Safari web browser. Its online services include the iTunes Store, the iOS App Store and Mac App Store, Apple Music, Apple was founded by Steve Jobs, Steve Wozniak, and Ronald Wayne in April 1976 to develop and sell personal computers. It was incorporated as Apple Computer, Inc. in January 1977, Apple joined the Dow Jones Industrial Average in March 2015. In November 2014, Apple became the first U. S. company to be valued at over US$700 billion in addition to being the largest publicly traded corporation in the world by market capitalization. The company employs 115,000 full-time employees as of July 2015 and it operates the online Apple Store and iTunes Store, the latter of which is the worlds largest music retailer. Consumers use more than one billion Apple products worldwide as of March 2016, Apples worldwide annual revenue totaled $233 billion for the fiscal year ending in September 2015. This revenue accounts for approximately 1. 25% of the total United States GDP.1 billion, the corporation receives significant criticism regarding the labor practices of its contractors and its environmental and business practices, including the origins of source materials. Apple was founded on April 1,1976, by Steve Jobs, Steve Wozniak, the Apple I kits were computers single-handedly designed and hand-built by Wozniak and first shown to the public at the Homebrew Computer Club. The Apple I was sold as a motherboard, which was less than what is now considered a personal computer. The Apple I went on sale in July 1976 and was market-priced at $666.66, Apple was incorporated January 3,1977, without Wayne, who sold his share of the company back to Jobs and Wozniak for $800. Multimillionaire Mike Markkula provided essential business expertise and funding of $250,000 during the incorporation of Apple, during the first five years of operations revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980 yearly sales grew from $775,000 to $118m, the Apple II, also invented by Wozniak, was introduced on April 16,1977, at the first West Coast Computer Faire. It differed from its rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics. While early Apple II models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a 5 1/4 inch floppy disk drive and interface called the Disk II. The Apple II was chosen to be the platform for the first killer app of the business world, VisiCalc. VisiCalc created a market for the Apple II and gave home users an additional reason to buy an Apple II. Before VisiCalc, Apple had been a distant third place competitor to Commodore, by the end of the 1970s, Apple had a staff of computer designers and a production line

Facebook is an American for-profit corporation and an online social media and social networking service based in Menlo Park, California. Facebook gradually added support for students at other universities. Since 2006, anyone age 13 and older has been allowed to become a user of Facebook, though variations exist in the minimum age requirement. The Facebook name comes from the face book directories often given to United States university students, Facebook may be accessed by a large range of desktops, laptops, tablet computers, and smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile indicating their name, occupation, schools attended and so on. Additionally, users may join common-interest user groups organized by workplace, school, hobbies or other topics, in groups, editors can pin posts to top. Additionally, users can complain about or block unpleasant people, because of the large volume of data that users submit to the service, Facebook has come under scrutiny for its privacy policies. Facebook makes most of its revenue from advertisements which appear onscreen, Facebook, Inc. held its initial public offering in February 2012, and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. On July 13,2015, Facebook became the fastest company in the Standard & Poors 500 Index to reach a market cap of $250 billion, Facebook has more than 1.86 billion monthly active users as of December 31,2016. As of April 2016, Facebook was the most popular social networking site in the world, Facebook classifies users from the ages of 13 to 18 as minors and therefore sets their profiles to share content with friends only. Zuckerberg wrote a program called Facemash on October 28,2003 while attending Harvard University as a sophomore, to accomplish this, Zuckerberg hacked into protected areas of Harvards computer network and copied private dormitory ID images. Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online, the site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg faced expulsion and was charged by the administration with breach of security, violating copyrights, Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final exam. He uploaded 500 Augustan images to a website, each of which was featured with a corresponding comments section and he shared the site with his classmates, and people started sharing notes. The following semester, Zuckerberg began writing code for a new website in January 2004 and he said that he was inspired by an editorial about the Facemash incident in The Harvard Crimson. On February 4,2004, Zuckerberg launched Thefacebook, originally located at thefacebook. com. com and they claimed that he was instead using their ideas to build a competing product. The three complained to The Harvard Crimson and the newspaper began an investigation and they later filed a lawsuit against Zuckerberg, subsequently settling in 2008 for 1.2 million shares. Membership was initially restricted to students of Harvard College, within the first month, eduardo Saverin, Dustin Moskovitz, Andrew McCollum, and Chris Hughes joined Zuckerberg to help promote the website

Huawei Technologies Co. Ltd. is a Chinese multinational networking and telecommunications equipment and services company headquartered in Shenzhen, Guangdong. It is the largest telecommunications equipment manufacturer in the world, having overtaken Ericsson in 2012, Huawei was founded in 1987 by Ren Zhengfei, a former engineer in the Peoples Liberation Army. Huawei has over 170,000 employees as of September 2015, around 76,000 of whom are engaged in research and development.4 billion USD in R&D, in 2014, Huawei recorded a profit of 34.2 billion CNY. Its products and services have been deployed in more than 140 countries, Huawei is the official translation of the firms Chinese name. The etymology of the character 华 is derived from 花 which means flower and this is hinted at in Huaweis logo. The character can also mean splendid or magnificent, but nowadays mostly refers to China or Chinese and it is common for Chinese companies to use this word, another example being the Taiwanese company Asus that was founded back in 1989. The second character of Huaweis name, 为, means action or achievement and it is pronounced Wah-Way according to a Gizmodo video that claims to provide the official pronunciation, as well as many other internet sources. However, Wah-Way is incorrect, and is a perpetuation of a mistaken combination of the Cantonese and Mandarin pronunciations for the first and second characters. The Cantonese pronunciation is Wah-Waii, while the Mandarin pronunciation is Hwa-Way, although the company is based in the Cantonese-speaking area of Guangdong, the use of Huawei as the spelling for its name reflects the Mandarin pronunciation the two characters. During the 1980s, Chinas government tried to modernize the countrys underdeveloped telecommunications infrastructure, Ren Zhengfei, a former deputy director of the Peoples Liberation Army engineering corp, founded Huawei in 1987 in Shenzhen. At a time all of Chinas telecommunications technology was imported from abroad. The company reports that it had RMB21,000 in registered capital at the time of its founding, the Far Eastern Economic Review also reported that it received an $8.5 million loan from a state-owned bank, though the company has denied the existence of the loan. During its first several years the business model consisted mainly of reselling private branch exchange switches imported from Hong Kong. Meanwhile, it was reverse-engineering imported switches and investing heavily in research, by 1990 the company had approximately 600 R&D staff, and began its own independent commercialization of PBX switches targeting hotels and small enterprises. The companys first major breakthrough came in 1993, when it launched its C&C08 program controlled telephone switch and it was by far the most powerful switch available in China at the time. By initially deploying in small cities and rural areas and placing emphasis on service and customizability, ahrens writes that these methods were unorthodox, bordering on corrupt, but not illegal. Jiang reportedly agreed with this assessment, Huawei was promoted by both the government and the military as a national champion, and established new research and development offices. In 1997, Huawei won its first overseas contract, providing fixed-line network products to Hong Kong company Hutchison Whampoa, later that year, Huawei launched its wireless GSM-based products and eventually expanded to offer CDMA and UMTS

International Business Machines Corporation is an American multinational technology company headquartered in Armonk, New York, United States, with operations in over 170 countries. The company originated in 1911 as the Computing-Tabulating-Recording Company and was renamed International Business Machines in 1924, IBM manufactures and markets computer hardware, middleware and software, and offers hosting and consulting services in areas ranging from mainframe computers to nanotechnology. IBM is also a research organization, holding the record for most patents generated by a business for 24 consecutive years. IBM has continually shifted its business mix by exiting commoditizing markets and focusing on higher-value, also in 2014, IBM announced that it would go fabless, continuing to design semiconductors, but offloading manufacturing to GlobalFoundries. Nicknamed Big Blue, IBM is one of 30 companies included in the Dow Jones Industrial Average and one of the worlds largest employers, with nearly 380,000 employees. Known as IBMers, IBM employees have been awarded five Nobel Prizes, six Turing Awards, ten National Medals of Technology, in the 1880s, technologies emerged that would ultimately form the core of what would become International Business Machines. On June 16,1911, their four companies were amalgamated in New York State by Charles Ranlett Flint forming a fifth company, the Computing-Tabulating-Recording Company based in Endicott, New York. The five companies had 1,300 employees and offices and plants in Endicott and Binghamton, New York, Dayton, Ohio, Detroit, Michigan, Washington, D. C. and Toronto. They manufactured machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards. Thomas J. Watson, Sr. fired from the National Cash Register Company by John Henry Patterson, called on Flint and, Watson joined CTR as General Manager then,11 months later, was made President when court cases relating to his time at NCR were resolved. Having learned Pattersons pioneering business practices, Watson proceeded to put the stamp of NCR onto CTRs companies and his favorite slogan, THINK, became a mantra for each companys employees. During Watsons first four years, revenues more than doubled to $9 million, Watson had never liked the clumsy hyphenated title of the CTR and in 1924 chose to replace it with the more expansive title International Business Machines. By 1933 most of the subsidiaries had been merged into one company, in 1937, IBMs tabulating equipment enabled organizations to process unprecedented amounts of data, its clients including the U. S. During the Second World War the company produced small arms for the American war effort, in 1949, Thomas Watson, Sr. created IBM World Trade Corporation, a subsidiary of IBM focused on foreign operations. In 1952, he stepped down after almost 40 years at the company helm, in 1957, the FORTRAN scientific programming language was developed. In 1961, IBM developed the SABRE reservation system for American Airlines, in 1963, IBM employees and computers helped NASA track the orbital flight of the Mercury astronauts. A year later it moved its headquarters from New York City to Armonk. The latter half of the 1960s saw IBM continue its support of space exploration, on April 7,1964, IBM announced the first computer system family, the IBM System/360

Microsoft
–
Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office office suite, and Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface tablet lineup, as of 2016, it was the worlds largest software maker by revenue, and one of the worlds most valuable companies. Microsoft was founded by Paul Allen and Bill Gates on April 4,1975, to develop and it rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Microsoft Windows. The companys 1986 initial public offering, and subsequent rise in its share price, since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions. In May 2011, Microsoft acquired Skype Technologies for $8.5 billion, in June 2012, Microsoft entered the personal computer production market for the first time, with the launch of the Microsoft Surface, a line of tablet computers. The word Microsoft is a portmanteau of microcomputer and software, Paul Allen and Bill Gates, childhood friends with a passion for computer programming, sought to make a successful business utilizing their shared skills. In 1972 they founded their first company, named Traf-O-Data, which offered a computer that tracked and analyzed automobile traffic data. Allen went on to pursue a degree in science at Washington State University. The January 1975 issue of Popular Electronics featured Micro Instrumentation and Telemetry Systemss Altair 8800 microcomputer, Allen suggested that they could program a BASIC interpreter for the device, after a call from Gates claiming to have a working interpreter, MITS requested a demonstration. Since they didnt actually have one, Allen worked on a simulator for the Altair while Gates developed the interpreter and they officially established Microsoft on April 4,1975, with Gates as the CEO. Allen came up with the name of Micro-Soft, as recounted in a 1995 Fortune magazine article. In August 1977 the company formed an agreement with ASCII Magazine in Japan, resulting in its first international office, the company moved to a new home in Bellevue, Washington in January 1979. Microsoft entered the OS business in 1980 with its own version of Unix, however, it was MS-DOS that solidified the companys dominance. For this deal, Microsoft purchased a CP/M clone called 86-DOS from Seattle Computer Products, branding it as MS-DOS, following the release of the IBM PC in August 1981, Microsoft retained ownership of MS-DOS. Since IBM copyrighted the IBM PC BIOS, other companies had to engineer it in order for non-IBM hardware to run as IBM PC compatibles. Due to various factors, such as MS-DOSs available software selection, the company expanded into new markets with the release of the Microsoft Mouse in 1983, as well as with a publishing division named Microsoft Press. Paul Allen resigned from Microsoft in 1983 after developing Hodgkins disease, while jointly developing a new OS with IBM in 1984, OS/2, Microsoft released Microsoft Windows, a graphical extension for MS-DOS, on November 20,1985. Once Microsoft informed IBM of NT, the OS/2 partnership deteriorated, in 1990, Microsoft introduced its office suite, Microsoft Office

Oracle Corporation is a multinational computer technology corporation, headquartered in Redwood Shores, California. In 2015 Oracle was the second-largest software maker by revenue, after Microsoft, larry Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates under the name Software Development Laboratories. Ellison took inspiration from the 1970 paper written by Edgar F. Codd on relational database management systems named A Relational Model of Data for Large Shared Data Banks and he heard about the IBM System R database from an article in the IBM Research Journal provided by Oates. Also derived from Codds theories, Ellison wanted to make Oracles product compatible with System R, SDL changed its name to Relational Software, Inc in 1979, then again to Oracle Systems Corporation in 1982, to align itself more closely with its flagship product Oracle Database. At this stage Bob Miner served as the senior programmer. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation, officially named Oracle, but sometimes referred to as Oracle Corporation, part of Oracle Corporations early success arose from using the C programming language to implement its products. This eased porting to different operating systems, many of the products have been added to Oracles portfolio through acquisitions. Oracles E-delivery service provides generic downloadable Oracle software and documentation, Oracle Database Release 10, In 2004, Oracle Corporation shipped release 10g as the then latest version of Oracle Database. Release 11, Release 11g became the current Oracle Database version in 2007, Oracle Corporation released Oracle Database 11g Release 2 in September 2009. This version was available in four commercial editions—Enterprise Edition, Standard Edition, Standard Edition One, the licensing of these editions shows various restrictions and obligations that are considered complex. The Enterprise Edition, the most expensive of the Database Editions, has the fewest restrictions —, Oracle Corporation constrains the Standard Edition and Standard Edition One with more licensing restrictions, in accordance with their lower price. Release 12, Release 12c became available on July 1,2013, Oracle acquired Rdb in 1994 from Digital Equipment Corporation. Oracle has since made many enhancements to product and development continues as of 2008. Released in 2008, the Oracle Beehive collaboration software provides team workspaces, email, calendar, instant messaging, customers can use Beehive as licensed software or as software as a service. Oracle also sells a suite of business applications, users can access these facilities through a browser interface over the Internet or via a corporate intranet. The Social Engagement and Monitoring cloud provides the most effective and efficient responses across social, SEM is able to route correct responses to the right team, member, or customer-experience channel to ensure the best customer service. The analysis helps vendors to understand what is important to customers and it identifies trends, spikes, and anomalies to make real-time course corrections. It also can identify brand advocates, the SEM cloud identifies customer intention and interests by analyzing the common ways customers talk about a product or a service

Yahoo Inc. is an American multinational technology company headquartered in Sunnyvale, California. Yahoo was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 2,1995, Yahoo was one of the pioneers of the early internet era in the 1990s. Marissa Mayer, a former Google executive, Google Employee number 20 and it is globally known for its Web portal, search engine Yahoo. Search, and related services, including Yahoo, answers, advertising, online mapping, video sharing, fantasy sports, and its social media website. It is one of the most popular sites in the United States, according to news sources, roughly 700 million people visit Yahoo websites every month. Yahoo itself claims it attracts more than half a billion consumers every month in more than 30 languages, in January 1994 Yang and Filo were electrical engineering graduate students at Stanford University, when they created a website named Jerry and Davids guide to the World Wide Web. The site was a directory of websites, organized in a hierarchy. In March 1994, Jerry and Davids Guide to the World Wide Web was renamed Yahoo, the yahoo. com domain was created on January 18,1995. The word yahoo is a backronym for Yet Another Hierarchically Organized Oracle or Yet Another Hierarchical Officious Oracle, the term hierarchical described how the Yahoo database was arranged in layers of subcategories. However, Filo and Yang insist they mainly selected the name because they liked the definition of a yahoo, rude, unsophisticated. This meaning derives from the Yahoo race of beings from Gullivers Travels. Yahoo grew rapidly throughout the 1990s, like many search engines and web directories, Yahoo added a web portal. By 1998, Yahoo was the most popular starting point for web users and it also made many high-profile acquisitions. Its stock price skyrocketed during the bubble, Yahoo stocks closing at an all-time high of $118.75 a share on January 3,2000. However, after the bubble burst, it reached a post-bubble low of $8.11 on September 26,2001. Yahoo began using Google for search in 2000, over the next four years, it developed its own search technologies, which it began using in 2004. In response to Googles Gmail, Yahoo began to offer unlimited email storage in 2007, the company struggled through 2008, with several large layoffs. In February 2008, Microsoft Corporation made a bid to acquire Yahoo for $44.6 billion

SAP SE is a German multinational software corporation that makes enterprise software to manage business operations and customer relations. SAP is headquartered in Walldorf, Baden-Württemberg, with offices in 130 countries. The company has over 335,000 customers in 190 countries, the company is a component of the Euro Stoxx 50 stock market index. When Xerox aimed to exit the industry in 1975, they asked IBM to migrate their business systems to IBM technology. As part of IBMs compensation for the migration, IBM was given the rights to the Scientific Data Systems /SAPE software, five IBM engineers from the AI department were working in an enterprise-wide system based on this software, only to be told that it would no longer be necessary. Rather than abandon the project, they decided to leave IBM Tech, in June 1970, they founded Systemanalyse und Programmentwicklung company, as a private partnership under the German Civil Code. Their first client was the German branch of Imperial Chemical Industries in Östringen, instead of storing the data on punch cards mechanically, as IBM did, they stored it locally. Therefore, they called their software a real-time system, since there was no need to process the punch cards overnight and this first version was also a standalone software that could be offered to other interested parties. In 1973, the first commercial product was launched and it was called SAP R/98, and offered a common system for multiple tasks. This permitted the use of a data storage, improving the maintenance of data. From a technical point of view, therefore, a database was necessary, in 1976, SAP GmbH was founded, and moved its headquarters the following year to Walldorf, Germany. Three years later, in 1979, SAP launched SAP R/2, expanding the capabilities of the system to other areas, such as material management, in 1981, SAP brought a re-designed product to market. However, SAP R/2 did not improve until the period between 1985 and 1990, SAP released the new SAP R/3 in 1992. SAP developed and released versions of R/3 through 1995. By the mid-1990s, SAP followed the trend from mainframe computing to client/server architectures, the development of SAP’s internet strategy with mySAP. com redesigned the concept of business processes. As a result, R/3 was replaced with the introduction of SAP ERP Central Component 5.0 in 2004, architectural changes were also made to support an enterprise service architecture to transition customers to a services-oriented architecture. The latest version, SAP ERP6.0, was released in 2006, SAP ERP6.0 has since then been updated through SAP enhancement packs, the most recent, SAP enhancement package 8 for SAP ERP6.0 in 2016. In August 1988, SAP GmbH became SAP AG, and public trading started on 4 November 1988, shares were listed on the Frankfurt and Stuttgart stock exchanges

Standards organization
–
Most standards are voluntary in the sense that they are offered for adoption by people or industry without being mandated in law. Some standards become mandatory when they are adopted by regulators as legal requirements in particular domains, the term formal standard refers specifically to a specification that has been approved by a standards setting organization. The term de jure standard refers to a standard mandated by legal requirements or refers generally to any formal standard, in contrast, the term de facto standard refers to a specification that has achieved widespread use and acceptance – often without being approved by any standards organization. The implementation of standards in industry and commerce became highly important with the onset of the Industrial Revolution, henry Maudslay developed the first industrially practical screw-cutting lathe in 1800, which allowed for the standardisation of screw thread sizes for the first time. Maudslays work, as well as the contributions of other engineers, accomplished a modest amount of industry standardization, joseph Whitworths screw thread measurements were adopted as the first national standard by companies around the country in 1841. It came to be known as the British Standard Whitworth, and was adopted in other countries. By the end of the 19th century differences in standards between companies was making trade increasingly difficult and strained, in this country no two professional men are agreed upon the size and weight of a girder to employ for given work. The Engineering Standards Committee was established in London in 1901 as the worlds first national standards body, the national standards were adopted universally throughout the country, and enabled the markets to act more rationally and efficiently, with an increased level of cooperation. After the First World War, similar national bodies were established in other countries, by the mid to late 19th century, efforts were being made to standardize electrical measurement. An important figure was R. E. B, Crompton, who became concerned by the large range of different standards and systems used by electrical engineering companies and scientists in the early 20th century. Many companies had entered the market in the 1890s and all chose their own settings for voltage, frequency, current, adjacent buildings would have totally incompatible electrical systems simply because they had been fitted out by different companies. Crompton could see the lack of efficiency in this system and began to consider proposals for a standard for electric engineering. In 1904, Crompton represented Britain at the Louisiana Purchase Exposition in St. Louis, Missouri and he presented a paper on standardisation, which was so well received that he was asked to look into the formation of a commission to oversee the process. By 1906 his work was complete and he drew up a permanent constitution for the first international standards organization, the body held its first meeting that year in London, with representatives from 14 countries. In honour of his contribution to electrical standardisation, Lord Kelvin was elected as the bodys first President, the International Federation of the National Standardizing Associations was founded in 1926 with a broader remit to enhance international cooperation for all technical standards and specifications. The body was suspended in 1942 during World War II, after the war, ISA was approached by the recently formed United Nations Standards Coordinating Committee with a proposal to form a new global standards body. Standards organizations can be classified by their role, position, and the extent of their influence on the local, national, regional, by geographic designation, there are international, regional, and national standards bodies. By technology or industry designation, there are standards developing organizations, Standards organizations may be governmental, quasi-governmental or non-governmental entities

W3C
–
The World Wide Web Consortium is the main international standards organization for the World Wide Web. As of 1 April 2017, the World Wide Web Consortium has 461 members, the W3C also engages in education and outreach, develops software and serves as an open forum for discussion about the Web. The World Wide Web Consortium was founded by Tim Berners-Lee after he left the European Organization for Nuclear Research in October,1994, the organization tries to foster compatibility and agreement among industry members in the adoption of new standards defined by the W3C. Incompatible versions of HTML are offered by different vendors, causing inconsistency in how web pages are displayed, the consortium tries to get all those vendors to implement a set of core principles and components which are chosen by the consortium. It was originally intended that CERN host the European branch of W3C, however, CERN wished to focus on particle physics, not information technology. In April 1995, the French Institute for Research in Computer Science and Automation became the European host of W3C, starting in 1997, W3C created regional offices around the world. In October 2012, W3C convened a community of major web players and publishers to establish a MediaWiki wiki that seeks to document open web standards called the WebPlatform and WebPlatform Docs. Sometimes, when a specification becomes too large, it is split into independent modules which can mature at their own pace, subsequent editions of a module or specification are known as levels and are denoted by the first integer in the title. Subsequent revisions on each level are denoted by a following an decimal point. The W3C standard formation process is defined within the W3C process document, after enough content has been gathered from editor drafts and discussion, it may be published as a working draft for review by the community. A WD document is the first form of a standard that is publicly available, commentary by virtually anyone is accepted, though no promises are made with regard to action on any particular element commented upon. At this stage, the document may have significant differences from its final form. As such, anyone who implements WD standards should be ready to significantly modify their implementations as the standard matures, a candidate recommendation is a version of a standard that is more mature than the WD. At this point, the responsible for the standard is satisfied that the standard meets its goal. The purpose of the CR is to aid from the development community as to how implementable the standard is. The standard document may change further, but at this point, significant features are mostly decided, the design of those features can still change due to feedback from implementors. A proposed recommendation is the version of a standard that has passed the two levels. The users of the standard provide input, at this stage, the document is submitted to the W3C Advisory Council for final approval

IETF
–
The Internet Engineering Task Force develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite. It is a standards organization, with no formal membership or membership requirements. All participants and managers are volunteers, though their work is funded by their employers or sponsors. Each working group has a chairperson, along with a charter that describes its focus, and what. It is open to all who want to participate, and holds discussions on a mailing list or at IETF meetings. Rough consensus is the basis for decision making. There are no formal voting procedures, because the majority of the IETFs work is done via mailing lists, meeting attendance is not required for contributors. Each working group is intended to work on its topic. In some cases, the WG will instead have its charter updated to take on new tasks as appropriate, the working groups are organized into areas by subject matter. Current areas are Applications, General, Internet, Operations and Management, Real-time Applications and Infrastructure, Routing, Security, each area is overseen by an area director, with most areas having two co-ADs. The ADs are responsible for appointing working group chairs, the area directors, together with the IETF Chair, form the Internet Engineering Steering Group, which is responsible for the overall operation of the IETF. The IETF is overseen by the Internet Architecture Board, which oversees its external relationships, the IAB is also jointly responsible for the IETF Administrative Oversight Committee, which oversees the IETF Administrative Support Activity, which provides logistical, etc. support for the IETF. The IAB also manages the Internet Research Task Force, with which the IETF has a number of cross-group relations. A Nominating Committee of ten randomly chosen volunteers who participate regularly at meetings is vested with the power to appoint, reappoint, and remove members of the IESG, IAB, IASA, and the IAOC. To date, no one has been removed by a NomCom, although people have resigned their positions. Because the IETF itself does not have members, nor is it an organization per se, IETF activities are funded by meeting fees, meeting sponsors and by the Internet Society via its organizational membership and the proceeds of the Public Interest Registry. In December 2005 the IETF Trust was established to manage the copyrighted materials produced by the IETF, the first IETF meeting was attended by 21 U. S. -government-funded researchers on 16 January 1986. It was a continuation of the work of the earlier GADS Task Force, representatives from non-governmental entities were invited to attend starting with the fourth IETF meeting in October 1986

ECMA is a standards organization for information and communication systems. It acquired its current name in 1994, when the European Computer Manufacturers Association changed its name to reflect the global reach. As a consequence, the name is no longer considered an acronym, the organization was founded in 1961 to standardize computer systems in Europe. Ecma publications, including standards, can be copied by all interested parties without copyright restrictions. The development of standards and technical reports is done in co-operation with the national, European. Unlike national standardization bodies, Ecma is a membership-based organization and it takes pride in the resulting business-like approach to standards, claimed to lead to better standards in less time, thanks to a less bureaucratic process focused on achieving results by consensus. Ecma has actively contributed to worldwide standardization in information technology and telecommunications, more than 400 Ecma Standards and 100 Technical Reports have been published, more than 2/3 of which have also been adopted as international standards and/or technical reports. The memberlist of Ecma International is available on its website, thus, Ecma is not responsible for the standardization of Java. Ecma is involved in the standardization of the Ecma Office Open XML format based on the XML office document formats by Microsoft, the Ecma Office Open XML maintenance process is performed by technical committee 45

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

The UCS is a standard to map characters used in natural language, mathematics, music. By creating this mapping, the UCS enables computer software vendors to interoperate, because it is a universal map, it can be used to represent multiple languages at the same time. UCS has a capacity to encode over 1 million characters. Each UCS character is represented by a code point, which is an integer between 0 and 1,114,111, used to represent each character within the internal logic of text processing software. The number of encoded characters is made up as follows,128,019 graphical characters 218 special purpose characters for control, ISO maintains the basic mapping of characters from character name to code point. Often the terms character and code point will get used interchangeably, however, when a distinction is made, a code point refers to the integer of the character, what one might think of as its address. Input methods can be through keyboard or a character palette. The UCS can be divided in various ways, such as by plane, block, character category, the x must be lowercase in XML documents. The nnnn or hhhh may be any number of digits and may include leading zeros, the hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, an entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined or explicitly declared in a Document Type Definition, the format is the same as for any entity reference, &name, where name is the case-sensitive name of the entity. Unicode and ISO divide the set of points into 17 planes. As of 2016 ISO and the Unicode Consortium has only allocated characters, the others remain empty and reserved for future use. Most characters are assigned to the first plane, the Basic Multilingual Plane. This is to ease the transition for legacy software since the Basic Multilingual Plane is addressable with just two octets. The characters outside the first plane usually have very specialized or rare use. Each plane corresponds with the value of the one or two hexadecimal digits preceding the four ones, hence U+24321 is in Plane 2, U+4321 is in Plane 0

Apple Chancery) shows the synthesized common fraction on the left and the precomposed fraction glyph on the right as a rendering the plain text string “1 1⁄4 1¼”. Depending on the text environment, the single string “1 1⁄4” might yield either result, the one on the right through substitution of the fraction sequence with the single precomposed fraction glyph.

Plane (Unicode)
–
In the Unicode standard, a plane is a continuous group of 65,536 code points. There are 17 planes, identified by the numbers 0 to 16decimal, Plane 0 is the Basic Multilingual Plane, which contains most commonly-used characters. The higher planes 1 through 16 are called supplementary planes, or humorously astral planes, as of Unicode version 9.0, six of the planes have assigned code points, and four are named. The limit of 17 is due to the design of UTF-16, which can encode 16 supplementary planes and the BMP, to a value of 0x10FFFF. The encoding scheme used by UTF-8 was designed with a larger limit of 231 code points. Since Unicode limits the points to the 17 planes that can be encoded by UTF-16, code points above 0x10FFFF are invalid in UTF-8. The 17 planes can accommodate 1,114,112 code points, of these,2,048 are surrogates,66 are non-characters, and 137,468 are reserved for private use, leaving 974,530 for public assignment. Planes are further subdivided into Unicode blocks, which, unlike planes, the 273 blocks defined in Unicode 9.0 cover 24% of the possible code point space, and range in size from a minimum of 16 code points to a maximum of 65,536 code points. For future usage, ranges of characters have been mapped out for most known current and ancient writing systems. The first plane, plane 0, the Basic Multilingual Plane contains characters for almost all languages. A primary objective for the BMP is to support the unification of prior character sets as well as characters for writing, most of the assigned code points in the BMP are used to encode Chinese, Japanese, and Korean characters. The High Surrogates and Low Surrogate codes are reserved for encoding characters in UTF-16 by using a pair of 16-bit codes, one High Surrogate. A single surrogate code point will never be assigned a character,65,408 of the 65,536 code points in this plane have been allocated to a Unicode block, leaving just 128 code points in unallocated ranges. As of Unicode 9.0, the BMP comprises the following 161 blocks, Plane 1, the Supplementary Multilingual Plane, contains historic scripts, scripts include Linear B, Egyptian hieroglyphs, and cuneiform scripts, and also reform orthographies like Shavian and Deseret. Symbols and notations include historic and modern musical notation, mathematical alphanumerics, Emoji and other sets, and game symbols for playing cards, Mah Jongg. Plane 3 is tentatively named the Tertiary Ideographic Plane, but as of version 9.0 there are no characters assigned to it and it is reserved for Oracle Bone script, Bronze Script, Small Seal Script, additional CJK unified ideographs, and other historic ideographic scripts. It is not anticipated that all these planes will be used in the foreseeable future, the number of possible symbol characters that could arise outside of the context of writing systems is potentially huge. At the moment, these 11 planes out of 17 are unused, Plane 14, the Supplementary Special-purpose Plane, currently contains non-graphical characters

Zero-width non-joiner
–
The zero-width non-joiner is a non-printing character used in the computerization of writing systems that make use of ligatures. When placed between two characters that would otherwise be connected into a ligature, a ZWNJ causes them to be printed in their final and initial forms, respectively. This is also an effect of a character, but a ZWNJ is used when it is desirable to keep the words closer together or to connect a word with its morpheme. The ZWNJ is encoded in Unicode as U+200C ZERO WIDTH NON-JOINER, in certain languages, the ZWNJ is necessary for unambiguously specifying the correct typographic form of a character sequence. The ASCII control code unit separator was formerly used, in the Biblical Hebrew example, the placement of the holam dot to the left of the letter vav ⟨ו⟩ is correct. If a dot were placed over the ⟨ו⟩, it would resemble ⟨עוֹנוֹת⟩, in Modern Hebrew, there is no reason to use the ḥolam after the vav, and the ligature is not needed, so it is rarely used in Modern Hebrew typesetting. In German typography, ligatures may not cross the constituent boundaries within compounds, thus, in the first German example, the prefix Auf- is separated from the rest of the word to prohibit the ligature fl. Similarly in English, ligatures should not cross morpheme boundaries, for example, in some words fly and fish are morphemes but in others theyre not, therefore words like deafly and selfish should not have ligatures while dayfly and catfish should have them. Persian uses this character extensively for certain prefixes, suffixes and compound words, in Kannada, the characters ನ್ and ನ combine to from ನ್ನ, but when a ZWNJ is inserted between them, ನ್ನ would be seen. In Bengali, the characters র and the combined to র্য which is a conjugate glyph of র and য. Because অ্যা isnt a character rather it is written by 3 letters, to fix the problem ZWNJ is used. Examples, The words র্যাব, র্যান্ডম etc are fixed by inserting ZWNJ, without ZWNJ they are shown as র্যাব, র্যান্ডম. Besides, to write the words উদ্ঘাটন, ইক্রা, etc need ZWNJ too, Zero-width joiner Zero-width space Word divider Using the ZWNJ in Persian

This is a list of Unicode characters. The latest version of Unicode contains a repertoire of more than 128,000 characters covering 135 modern and historic scripts and this page includes the 1062 characters in the Multilingual European Character Set 2 subset, and some additional related characters. The x must be lowercase in XML documents, the nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style, in contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined or explicitly declared in a Document Type Definition, the format is the same as for any entity reference, &name, where name is the case-sensitive name of the entity. 65 characters, including DEL but not SP, all belong to the common script. The Unicode Standard classifies 1,338 characters as belonging to the Latin script,95 characters, the 52 alphabet characters belong to the Latin script.

CJK Unified Ideographs
–
The Chinese, Japanese and Korean scripts share a common background, collectively known as CJK characters. In the process called Han unification, the characters were identified and named CJK Unified Ideographs. As of Unicode 9.0, Unicode defines a total of 80,388 CJK Unified Ideographs, the terms ideographs or ideograms may be misleading, since the Chinese script is not strictly a picture writing system. Historically, Vietnam used Chinese ideographs too, so sometimes the abbreviation CJKV is used and this system was replaced by the Latin-based Vietnamese alphabet in the 1920s. The basic block named CJK Unified Ideographs contains 20,950 basic Chinese characters in the range U+4E00 through U+9FD5, the block not only includes characters used in the Chinese writing system but also kanji used in the Japanese writing system and hanja, whose use is diminishing in Korea. Many characters in block are used in all three writing systems, while others are in only one or two of the three. Chinese characters were used in Vietnams Nôm script. The first 20,902 characters in the block are arranged according to the Kangxi Dictionary ordering of radicals, in this system the characters written with the fewest strokes are listed first. The remaining characters were added later, and so are not in radical order, the block is the result of Han unification, which was somewhat controversial in the Far East. Since Chinese, Japanese and Korean characters were coded in the same location, however, the source separation rule states that characters encoded separately in an earlier character set would remain separate in the new Unicode encoding. Using variation selectors, it is possible to specify certain variant CJK ideograms within Unicode, the Adobe-Japan1 character set proposal, which actually calls for 14,679 ideographic variation sequences, is an extreme example of the use of variation selectors. Note, Most characters appear in sources, making the sum of individual character counts far more than the number of encoded characters. In Unicode 4.1,14 HKSCS-2004 characters and 8 GB18030 characters were assigned to between U+9FA6 and U+9FBB code points. The block named CJK Unified Ideographs Extension A contains 6,582 additional characters in the range U+3400 through U+4DB5 that were added in Unicode 3.0. Note, Most characters appear in more than one source, making the sum of individual character counts far more than the number of encoded characters. The block named CJK Unified Ideographs Extension B contains 42,711 characters in the range U+20000 through U+2A6D6 that were added in Unicode 3.1. These include most of the used in the Kangxi Dictionary that are not in the basic CJK Unified Ideographs block. 20000-215FF, 21600-230FF, 23100-245FF, 24600-260FF, 26100-275FF, 27600-290FF, note, Many characters appear in more than one source, making the sum of individual character counts far more than the number of encoded characters
