Portal:Internet
The Internet Portal  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 comprises private, public, academic, business, and government networks of local to global scope, linked by electronic, wireless, and optical networking technologies. The Internet carries a vast range of information services and resources, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, discussion groups, internet telephony, streaming media and file sharing. Most traditional communication media, including telephone, radio, television, paper mail, newspapers, and print publishing, have been transformed by the Internet, giving rise to new media such as email, online music, digital newspapers, news aggregators, and audio and video streaming websites. The Internet has enabled and accelerated new forms of personal interaction through instant messaging, Internet forums, and social networking services. Online shopping has also grown to occupy a significant market across industries, enabling firms to extend brick and mortar presences to serve larger markets. Business-to-business and financial services on the Internet affect supply chains across entire industries. (Full article...) Selected articleThe Arena browser (also known as the Arena WWW Browser) was one of the first web browsers for Unix. Originally begun by Dave Raggett in 1993, development continued at CERN and the World Wide Web Consortium (W3C) and subsequently by Yggdrasil Computing. Arena was used in testing the implementations for HTML version 3.0, Cascading Style Sheets (CSS), Portable Network Graphics (PNG), and libwww. Arena was widely used and popular at the beginning of the World Wide Web. Arena, which predated Netscape Navigator and Microsoft's Internet Explorer, featured a number of innovations used later in commercial products. It was the first browser to support background images, tables, text flow around images, and inline mathematical expressions. (Full article...)

Of the estimated 150 million laptops, 14 million PDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature. The Protocol Wars were a long-running debate in computer science that occurred from the 1970s to the 1990s, when engineers, organizations and nations became polarized over the issue of which communication protocol would result in the best and most robust networks. This culminated in the Internet–OSI Standards War in the 1980s and early 1990s, which was ultimately "won" by the Internet protocol suite (TCP/IP) by the mid-1990s when it became the dominant protocol suite through rapid adoption of the Internet. In the late 1960s and early 1970s, the pioneers of packet switching technology built computer networks providing data communication, that is the ability to transfer data between points or nodes. As more of these networks emerged in the mid to late 1970s, the debate about communication protocols became a "battle for access standards". An international collaboration between several national postal, telegraph and telephone (PTT) providers and commercial operators led to the X.25 standard in 1976, which was adopted on public data networks providing global coverage. Separately, proprietary data communication protocols emerged, most notably IBM's Systems Network Architecture in 1974 and Digital Equipment Corporation's DECnet in 1975. The United States Department of Defense (DoD) developed TCP/IP during the 1970s in collaboration with universities and researchers in the US, UK, and France. Internet Protocol version 4 (IPv4) was released in 1981 and was made the standard for all DoD computer networking. By 1984, the international reference model OSI model, which was not compatible with TCP/IP, had been agreed upon. Many European governments (particularly France, West Germany, and the UK) and the United States Department of Commerce mandated compliance with the OSI model, while the US Department of Defense planned to transition from TCP/IP to OSI. Meanwhile, the development of a complete Internet protocol suite by 1989, and partnerships with the telecommunication and computer industry to incorporate TCP/IP software into various operating systems, laid the foundation for the widespread adoption of TCP/IP as a comprehensive protocol suite. While OSI developed its networking standards in the late 1980s, TCP/IP came into widespread use on multi-vendor networks for internetworking and as the core component of the emerging Internet.
