Timeline of The
Internet and The Web
-
1960's:
"Packet-switching", ArpaNet
- 1961 Leonard
Kleinrock of MIT writes first paper on packet-switching theory, entitled "Information Flow in Large Communication
Nets." Packet switching is idea of breaking data into pieces,
rather than sending it as a continuous whole.
- 1962 J.C.R.
(Joseph Carl Robnett) Licklider of MIT writes a series of
memos titled "On-Line Man Computer Communication".
- Argues for a "Galactic Network", a globally interconnected
set of computers. Licklider was the first head of the computer research
program at DARPA, starting in October 1962.
- 1964 Paul
Baran at RAND corporation develops packet-switching networks and
produces several papers on distributed
communication networks. Work is funded by the Air Force and developed with a nuclear attack
in mind, in which networks could switch to one another if one were
destroyed. Referred to system as "hot-potato" routing.
- 1965 Larry Roberts and Thomas Marill, at the Lincoln
Laboratory of MIT, connected the TX-2 computer in Massachusetts to the
Q-32 in California with a low speed dial-up telephone line creating the
first (however small) wide-area computer network ever built.
(Circuit-switched telephone lines proved inadequate for connection -
thus proving need for packet-switching)
- 1966
Roberts heads to DARPA and begins developing plans for wide are network
- ARPANET.
- 1969
ARPANET goes online - UCLA, Stanford Research Institute(SRI), UC-Santa
Barbara, University of Utah. (Charley Kline of UCLA was first
user - tried to connect to SRI on Oct. 29. 1969, but system crashed as
he reached the G in LOGIN - from A Brief History
of the Internet)
