Today we all take for granted that we should have instant access to the Internet regardless if we're at home or at work. We can even browse the web while on the go thanks to cell phones. It obviously hasn't been like this for ages and to help clarify the progress of the Internet we've written you a timeline with the most important things happening. Although theInternet only has a brief history it's a very interesting one - especially because things have happened so fast. What one thought was impossible some 20 years ago is now a reality for all web users.
Give the history of the internet as a timeline to make more comprehensible the events that have made possible all the wonders and variety of activities that make us more comfortable and pleasant ourrelationship with our social environment and how we learn and we communicate with those around us.
1957 - It was this year that the USSR launched 'Sputnik', the first artificial earth satellite. The United States in reply formed the Advanced Research Projects Agency (ARPA) within the Department of Defense (DoD) to create US lead in science and technology applicable to the military.

1962 - The U.S. Air Force commissioned Rand Paul Baran, of the RAND Corporation (a government agency), to do a study on how it could maintain its control and command over its missiles and bombers, after a nuclear attack. It was to be a military research network that could survive a nuclear strike. It was decentralized so that if any locations in the U.S. were attacked, themilitary could still have control of nuclear arms for a counter-attack.
Baran's completed document explained the different ways to achieve this. His final proposal was a packet switched network - "Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computerto another computer until the information arrives at its final destination computer. This was crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator."

1968 - ARPA awarded the ARPANET contract to BBN. BBN had chosen a Honeywell minicomputer as the base to build the switch on. In 1969 theactual, physical network was constructed linking four nodes: University of California at Santa Barbara, and University of Utah, University of California at Los Angeles, and SRI (in Stanford. The network was wired together via 50 Kbps circuits.

1972 - Ray Tomlinson of BBN created the first e-mail program. The Advanced Research Projects Agency (ARPA) wasrenamed The Defense Advanced Research Projects Agency (or DARPA) ARPANET was currently using the Network Control Protocol or NCP to transfer data, allowing communications between hosts running on the same network.

1974 - It was in 1974 the term Internet was first used by Vint Cerf and Bob Kahn in paper on Transmission Control Protocol.

1976 - Ethernet was developed by Dr. Robert M. Metcalfe which allowed coaxial cable to move data extremely fast. This was a crucial component to the development of LANs. The packet satellite project was then put to practical use and Atlantic packet Satellite network, SATNET was born. It was this network that linked the United States with Europe. But surprisingly it used INTELSATsatellites that were owned by a consortium of countries and not exclusively the United States government. It was in AT&T Bell Labs that UUCP (Unix-to-Unix CoPy) was developed and distributed with UNIX one year later. The Department of Defense began to experiment with the TCP/IP protocol and soon decided to require it for use on ARPANET.
