Title: Internet
Content:  The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor

ARPANET evolved into the Internet following the publication of the first Transmission Control Protocol (TCP) specification, (Specification of Internet Transmission Control Program), written by Vint Cerf, Yogen Dalal and Carl Sunshine in 1974. This became the foundation of Usenet, conceived by Tom Truscott and Jim Ellis in 1979 at the University of North Carolina at Chapel Hill and Duke University, and established in 1980. A precursor of the electronic bulletin board system (BBS), known as Community Memory, appeared by 1973. True electronic BBSs arrived with the Computer Bulletin Board System in Chicago, which first came online on February 16, 1978. Before long, most major cities had more than one BBS running 
Title: History of the Internet
Content:  The World Wide Web (sometimes abbreviated "www" or "W3") is an information space where documents and other web resources are identified by URIs, interlinked by hypertext links, and can be accessed via the Internet using a web browser and (more recently) web-based applications. It has become known simply as "the Web". As of the 2010s, the World Wide Web is the primary tool billions use to interact on the Internet, and it has changed people's lives immeasurably. Precursors to the web browser emerged in the form of hyperlinked applications during the mid and late 1980s (the bare concept of hyperlinking had by then existed for

The main impetus for this was electronic mail, a far faster and convenient form of communication than a conventional letter and memo distribution, and the File Transfer Protocol (FTP). However, the Internet remained largely unknown to the general public, who were used to Bulletin Boards and services like Compuserve and America Online. This changed when Tim Berners-Lee devised a simpler form of Vannevar Bush's hypertext, which he dubbed the World Wide Web. "The Web" suddenly changed the Internet into a printing press beyond the geographic boundaries of physical countries; it was termed "cyberspace". Anyone with a computer 
Title: History of the Internet
Content:  E-mail has often been called the killer application of the Internet. It predates the Internet, and was a crucial tool in creating it. Email started in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate. Although the history is undocumented, among the first systems to have such a facility were the System Development Corporation (SDC) Q32 and the Compatible Time-Sharing System (CTSS) at MIT. The ARPANET computer network made a large contribution to the evolution of electronic mail. An experimental inter-system transferred mail on the ARPANET shortly after its creation. In 1971 Ray Tomlinson created what was to become the standard Internet electronic mail addressing format, using the @|@ sign to separate mailbox names from host names. A number of protocols were developed to deliver messages

Content:  In the 1950s and 1960s, with the creation of computers, is where the history of the Internet begins. In 1969 came the invention of ARPANET, the first network to run on packet-switching technology. These were the first hosts on what would one day become the Internet. The concept of email was first created by Ray Tomlinson in 1971, and this innovation was followed by Project Gutenberg and eBooks. Tim Berners-Lee is considered the inventor of the World Wide Web; he implemented the first successful communication between a HyperText Transfer Protocol client and a server. Because the Internet allowed users ease of access to information about practically any topic, the medium has seen immense popularity ever since its inception. There has never been

The technology had been inspired by Vannevar Bush's "Memex" and developed through Ted Nelson's research on Project Xanadu, Douglas Engelbart's research on NLS and Augment, and Andries van Dam's research from HES in 1968, through FRESS, Intermedia, and others. Many small self-contained hypertext systems had been created as well, such as Apple Computer's HyperCard (1987). Gopher became the first commonly used hypertext interface to the Internet. While Gopher menu items were examples of hypertext, they were not commonly perceived

Content:  The hypertext portion of the Web in particular has an intricate intellectual history; notable influences and precursors include Vannevar Bush's Memex, IBM's Generalized Markup Language, and Ted Nelson's Project Xanadu. Paul Otlet's Mundaneum project has also been named as an early 20th-century precursor of the Web. The concept of a global information system connecting homes is prefigured in "A Logic Named Joe", a 1946 short story by Murray Leinster, in which computer terminals, called "logics", are present in every home. Although the computer system in the story is centralized, the story anticipates a ubiquitous information environment similar to the Web. The cultural impact of the Web was imagined even further back in a short story by E. M. Forster, "The Machine Stops", first published in 1909.

Content:  1990, PSInet launched an alternate Internet backbone for commercial use; one of the networks that added to the core of the commercial Internet of later years. In March 1990, the first high-speed T1 (1.5 Mbit/s) link between the NSFNET and Europe was installed between Cornell University and CERN, allowing much more robust communications than were capable with satellites. Six months later Tim Berners-Lee would begin writing WorldWideWeb, the first web browser, after two years of lobbying CERN management. By Christmas 1990, Berners-Lee had built all the tools necessary for a working Web: the HyperText Transfer Protocol (HTTP) 0.9, the HyperText Markup Language (HTML), the
