HISTORY OF INTERNET The internet has it’s history anchored in the project started by the United States Government called DARPA (Defense Advanced Research Project Agency) an agency of the US Department of Defense for the development of new technology for military use which was establish in 1958.

The original name of this agency was simply ARPA (Advanced Research Project Agency) then was renamed to DARPA. The agency was then headed by J.C.R Licklider in 1962, he installed three computer network terminals; one for the University of California, Berkeley for the project Genie, one for System Development Corporation in Santa, Monica USA and one at Massachussetts Institute of Technology (MIT) for Time System project for advance computer and networking research.

The networking technology led to the development of what we call “packet switching”, a network communication that splits the data in chunks, called packets , then resembled in the correct order at its destination.

Robert Taylor as head of the Information Processing Office in DARPA with Larry Roberts from MIT initiated the project called ARPANET to build a networking computer network. The for inter connected computers were located in University of California, Los Angeles, Stanford research Institute, University of Utah and University of California of Santa Barbara.

ARPANET essentially was the pioneering technical contributor t what we know today as the Internet. The computer from different location basically becomes host, operating as the serves that provide services and communication to other network in the network.
