THE HISTORY OF YHE INTERNET
The Internet was born in the sixties, as a result of the “Cold
War” between the former Soviet Union and the US. At the time, the defense
system of the US was built up on computers, which were interconnected. A nuclear
attack on this central unit could bring the complete defense system of the US
to a standstill.
If a nuclear bomb blew up one computer, another computer
could instantly take over; thus, the computer network wouldn’t go down. So, the
internet was created by the U.S. Department of defense in 1969 under the name
ARPANet (ARPA was the department’s Advance Research Project Agency). It was
built to serve two purposes;
·
To share research among military, industry, and
university sources.
·
To provide a system for sustaining communication
among military units in the event of nuclear attack.
At first each computer was physically
linked by cable to the next computer, but this approach has obvious
limitations, which led to the development of networks utilizing the telephone
system. So the internet systems are based on the phoned systems , The internet
traffic basically travels over phone lines. Because of this reason the internet
and phone system are similar. The pictures and table help to understand showing
the similarities:
After invention of the internet, other
organizations, such as colleges and universities, home and office users started
connecting their computers to this growing network to share information.
