Evaluation of Internet History of Internet Growth

Evaluation of Internet

• The origin of Internet can be traced to a  U.S. Department of Defence (DoD) organization called Advanced Research Projects Ajency(ARPA).
• ARPA developed a four node packet switching network called ARPANET in 1969.The network was intended to support the military research on fault tolerant computer networks.DoD wnated to ensure a reliable data transfer in the event of a nuclear war, even if parts of the network ha been destroyed.
• As the years pass by, the ARPANET no longer remained an experimental network but its control was passed over to Defence Communication Agency(DCA).
• The network then became available for the academic research, government employee and contractors.
• It was not until 1986, however  that the dramatic growth of the Internet began.At this time, the National Science Foundation (NSF) which formed the National Science Foundation Network(NSFNET) Linked five of its regional super-computer centers together to provide a national high speed backbone network across the United states.
• The world's fastest and most powerful computers were made available to a academic and scientific community.
• In 1990, theARPANET was officially decommissioned.some of the major networks contributing to the growth of the internet are as follows :

1. ARPANET
2. USENET  (user's network)
3. CSNET (computer science network)
4. BITNET (because it's time network)
5. NSFNET (National Science Foundation Network)
6. WWW (World Wide Web)
7. NREN (National research and education network)
8. Intranet

• It is said that the Internet is growing at a rate of 20% per month.The data speeds have gone up considerably, which makes the access even more fast.
• The event which started as a military assistance program is now largely a private enterprise.
