Unformatted text preview: ating system. It is alleged that IBM approached Both Kidall and Gates. However, Kidall was out flying and failed to attend to IBM’s request before Gates did. Gates developed the first DOS and a version of the BASIC programming language for IBM and the rest is history for The Development of the Internet The Internet, a global network of computers, owes its development on the invention of four technologies: telegraph, telephone, radio, and computers. History has it that the Internet originated from the early work of J.C.R. Licklider of Massachusetts Institute of Technology (MIT) on "Galactic Networks". Networks". Licklider conceptualized a global interconnected set of computers with Licklider communication channels between them through which programs and data could be accessed quickly by any computer from any computer . The networking concept envisioned by Licklider would support communication between network nodes using a concept of packets instead of circuits, thus enabling computers to talk to each other. He left MIT to head the computer research program at the Department of Defense’s Defense Advanced Research Projects Agency (DARPA) in 1962. Defense’s A year before, in 1961 at MIT, researcher Leonard Kleinrock had published year what is believed to be the first published work on packet switching theory . what This work created the momentum for the packet switching network concept. However, it was not the only work on the concept, there were two additional independent projects on this same topic, that of Donald Davies and Roger Scantleberg at the British National Laboratory (BNL) which later was credited with coining the term "packet", and that of Paul Baran at RAND. that In 1965, Lawrence Roberts at MIT, who had been collaborating with Licklider, and Thomas M. Roberts connected and tested the TX-2 computer from Boston on the east coast of USA to the Q-32 computer in Los Angels on the west coast of the USA, with a low speed dial-up telephone line. This test experiment created the first working Wide Area Network (WAN). This experiment opened up doors for all computer network communications as known today. communications In 1966 Roberts left MIT for DARPA to develop the computer In network concept publishing the first plan for ARPNET in 1967. In 1968, a go ahead was given by DARPA for the development of the packet switches called Interface Message Processors (IMP). As the team, lead by Frank Heart and included Bob Kahn, developed the IMP, a team consisting of Roberts and Howard Frank designed the network topology and economics, and the network measurement system were done by Kleinrock and his team . The work of these teams led to the testing of the first IMP at UCLA in 1969 connected to a second node at Stanford Research Institute (SRI). After these tests, more nodes were added to ARPNET and by end of 1969 four nodes formed ARPNET [5]. From this point on the Internet started to grow. From However, more work was needed t...
