Unformatted text preview: o incorporate the However, host-to-host protocol into ARPNET. The first host-to-host protocol called Network Control Protocol (NCP) was developed by the Network Working Group (NWG) in 1970. But NCP did not have “the ability to address networks further downstream than a destination IMP on the ARPNET” . the Kahn then developed what later became the Kahn Transmission Control Protocol/Internet Protocol (TCP/IP). As the number of nodes increased, more universities joined the exclusive club, and APRANET became not only a research facilitator, but it also became a free federally funded postal system of electronic mail. In 1984, the U.S. National Science Foundation (NSF) joined ARPANET in starting its own network code named NSFNET. NSFNET set a new pace in nodes, bandwidth, speed and upgrades. This NSF funded network brought the Internet in the reach of many universities throughout the USA and internationally that would not otherwise afford the costs, and many government agencies joined in. At this point other countries and regions were establishing their own networks With so much success and fanfare, ARPANET ceased to exist in 1989. As the number of nodes on the Internet climbed into hundreds of thousands worldwide, the role of sponsoring agencies like ARPA and NSF became more and more marginalized. Eventually in 1994 NSF also ceased its support of the Internet. The Internet by now needed no helping hand since it had assumed a momentum of its own. own. The Development of the World Wide Web The World Wide Web, as we know it today, had its humble beginning from concepts contained in Tim Berners-Lee’s 1989 proposal to physicists calling for comments. Berners-Lee, a physicist researcher at the European High-Energy Particle Physics lab- the Conseil Europeenne pour la Recherché Nucleaire (CERN), Switzerland, wrote the proposal called HyperText and CERN, to enable HyperText N, collaboration between physicists and other researchers in the high energy physics research community. Three new technologies were incorporated. They were: HyperText Markup Language (HTML) based on the hypertext concepts- to be used to write web documents, HyperText Transfer Protocol (HTTP) a protocol to be used to transmit web pages between hosts, and a web browser client software program to receive and interpret data and display results. His proposal also included a very important concept for the user interface. This browser supported interface was based on the concept that it would be consistent across all types of computer platforms to enable users to access information from any computer. The line-mode interface was developed and named at CERN in late 1989 and it came to be known as the world wide web or www. www By 1991, the concept developed only two years back was put into practice on a limited network at CERN. From the central computer at CERN with few web pages, the number of servers started to grow from the only one at CERN in 1991, to 50 world wide by 1992, to 720,000 by...
