 BRIEF HISTORY OF THE INTERNET

During the 1960s ,The US defense department made an experiment that led them to the development of connected computer networks that should work as a coordinate whole.

Their purpose was to help their scientist and researchs from widely dispersed areas work as if they were in one place by sharing their files and resources.

A " cold war" existed at that time, and networks were not secured from enemy attack. Their solution was to build a  "bombproof" network, one that would be operational even when other parts of the networks were shut down. 

From this requirement , the defense department created the ARPANET(Advanced Research Projects Agency Network) in 1969 it was an experimental network based on packet switching techniquies..
