The fact about Internet!!!!!!!!!!

The U.S. Department of Defence in the 1960s wanted to create a computer network that would continue to funtion even in the event of a disaster. It was intented to be flexible so that if a part of the network was damaged or destroyed, the rest of the system would still work. The network they developed was called ARPANET (Advanced Reseach Projects Agency Network) and it inter-linked scientific and academic researchers in the U.S. This network is considered to be the forerunner of today,s Internet.
                                   In 1985, the U.S National Science Foundation (NSF) created NSFNET, an organisation comprising of series of networks for research and education related communication. Based on ARPANET protocols, the NSFNET created a national backbone service that provided free service to all research and educational institutions in the U.S. NSF also coordinated another service called Inter NIC, a body that registers new domain adresses with extension like, .com, .org, .edu etc on the Internet. Inatially, the basic purpose of the Internet was to help researchers and scientists gather scientific and defence related information. However, it has become a vital part of our lives now.
                                  Who run Internet?   The fact is that no centralized management of the Internet exists. The Internet is a collection of thousands of individual networks and organisation, each of which is run and paid for on its own.
