Internet celebrates its 30th birthday
The computer network officially began its technological revolution when
it fully substituted previous networking systems on January 1 1983.
“flag day”, it was the first time the US Department of Defence
(DoD)-commissioned Arpanet network fully switched to use of the Internet
protocol suite (IPS) communications system.
Using data “packet-switching”, the new method of linking computers paved the way for the arrival of the World Wide Web.
“ without the internet and the World Wide Web the day may not begin or the day may not end ".
Based on designs by Welsh scientist Donald Davies, the Arpanet network began as a military project in the late 1960s.
It was developed at prestigious American universities and research
laboratories, such as the University of California, Los Angeles (UCLA)
and the Stanford Research Institute.
Starting in 1973, work on the powerful and flexible IPS and Transmission
Control Protocol (TCP) technology which would change mass
communications got under way.
The new systems were designed to replace the more vulnerable Network
Control Program (NCP) used previously, making sure the network was not
exposed to a single point of failure.
This meant a single attack could not bring it down, making it safer and more reliable.
By January 1 1983, the substitution of the older system for the new
Internet protocol had been completed and the Internet was born.
British computer scientist Tim Berners-Lee was then able to use it to
host the system of interlinked hypertext documents he invented in 1989,
known as the World Wide Web.
