Now not talking more about the Fourier transforms (as itself is a big to be dealt here) we will now look in the matter of theoretical and practical networks. Now we know how the foundation stone of the communication was laid but when and how was this network developed is a different story.
Carrying instructions between calculation machines and early computers was done by human users. In September, 1940 George Stibitz used a teletype machine to send instructions for a problem set from his Model K at Dartmouth College in New Hampshire to his Complex Number Calculator in New York and received results back by the same means. Linking output systems like teletypes to computers was an interest at the Advanced Research Projects Agency ARPA when, in 1962, J.C.R. Licklider was hired and developed a working group he called the "Intergalactic Network", a precursor to the ARPANet. In 1964 researchers at Dartmouth developed a time sharing system for distributed users of large computer systems. The same year, at MIT, a research group supported by General Electric and Bell Labs used a computer (DEC's PDP-8) to route and manage telephone connections. In 1968 Paul Baran proposed a network system consisting of datagrams or packets that could be used in a packet switching network between computer systems. In 1969 the University of California at Los Angeles, SRI (in Stanford), University of California at Santa Barbara, and the University of Utah were connected as the beginning of the ARPANet network using 50 kbit/s circuits So this found the beginning of what we say today as WWW or the internet. It has been a long time and many technologies have evolved which are now a part of this network. Some of the Important dates in the computer network history:
-
Timesharing, the concept of linking a large numbers of users to a single computer via remote terminals, is developed at MIT in the late 50s and early 60s.
- 1962: Paul Baran of RAND develops the idea of distributed, packet-switching networks.
- ARPANET goes online in 1969.
- Bob Kahn and Vint Cerf develop the basic ideas of the Internet in 1973.
- In 1974 BBN opens the first public packet-switched network – Telenet.
- A UUCP link between the University of North Carolina at Chapel Hill and Duke University establishes USENET in 1979. The first MUD is also developed in 1979, at the University of Essex.
- TCP/IP (Transmission Control Protocol and Internet Protocol) is established as the standard for ARPANET in 1982.
- 1987: the number of network hosts breaks 10,000.
- 1989: the number of hosts breaks 100,000.
-
Tim Berners-Lee develops the World Wide Web. CERN releases the first Web server in 1991.
- 1992: the number of hosts breaks 1,000,000.
- The World Wide Web sports a growth rate of 341,634% in service traffic in its third year, 1993.
- The main U.S. Internet backbone traffic begins routing through commercial providers as NSFNET reverts to a research network in 1994.
- The Internet 1996 World Exposition is the first World's Fair to be held on the internet.
