History:
The ancestor of the Internet was ARPANET a project funded by department of Defense (DOD) in 1969, both as an experiment in reliable networking and to link DOD and military research contractors, including large number of universities doing military funded research. In start ARPANCT started small, connecting three computers in different places, but it quickly grew to span the continent.
ARPANET was widely successful because of I. response. It was broken to two parts MILNET which had the military sites and new smaller ARPANET which had non-military sites. Two sites remained connected, however, through a technical scheme called IP. IP (Internet protocol) acted as a rule for data transmission. |
