The History Of The Internet


            The history of the internet is a brief one, of course. It's brief because the internet (in one form or another) has only been around for about 30 years. The first instance of the Internet was launched in 1971 with a public showing in early 1972. This first network, known as ARPANET (Advanced Research Projects Agency NETwork), was very primitive by today's standards, but a milestone in computer communications. ARPANET was based upon the design concepts of Larry Roberts (MIT) and was fleshed out at the first ACM symposium, held in Gaithersburg, TN in 1966, although RFPs weren't sent out until mid 1968.
             The Department of Defense in 1969 commissioned ARPANET, and the first node was created at the University of California in Los Angeles, running on a Honeywell DDP-516 mini-computer. The second node was established at Stanford University and launched on October first of the same year. On November 1, 1969, the third node was located at the University of California, Santa Barbara and the fourth was opened at the University of Utah in December. By 1971, 15 nodes were linked including BBN, CMU, CWRU, Harvard, Lincoln Lab, MIT, NASA/Ames, RAND, SDC, SRI and UIU(C). In that same year, Larry Roberts created the first email management program. As a side note, Ray Tomlinson is the person who established the @ sign as a domain/host designator from his Model 33 Teletype. The first international connection to ARPANET is established when the University College of London is connected in 1973, and RFC-454 File Transfer Protocol was published. 1973 was also the year that Dr. Robert Metcalf's doctoral thesis outlined the specifications for Ethernet. The theory was tested on Xerox PARCs computers. 1974 saw the launch of TELNET public packet data service. UUCP (Unix-to-Unix Copy Protocol) was developed at AT&T Bell Labs in 1976, and distributed with UNIX the following year. 1978 saw the split of TCP into TCP and IP.
