Introduction of First Internet Network

The Internet was not originally built to be what it is today. It was developed when computers 

were hugs  and so expensive to own that only university, big business and a few governments

had them. Originally, the the internet was designed to facilitate these massive computers to 

communication each other by sending information (mainly text) back and forth. with the internet,

the network began to take shape. It was only in 1969, the advanced Research Project Agency 

Network (ARPANET)-------the first computer network was built. 

                                                           The Internet gradually grew, until the emergency og personal computer in the 1980s, and then it became widespread. 

ABOUT ARPANET :

The ARPANET (an Advanced Research Projects Agency for Advanced Research Projects Agency Network) was the first wide-area packet-swithing network with distributed control and one of the first networks to implement the TCP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the  Advanced Research Projects Agency (ARPA) of the United States Department of Defensef 

Building on the ideas of J. C. R. Licklider initiated the ARPANET project in 1966 to enable access to remote computers. Taylor appointed Larry Roberts as program manager. Roberts made the key decisions about the network design. He incorporated Donald Davies’ concepts and designs for packet switching, and sought input from Paul Baran. ARPA awarded the contract to build the network to Bolt Beranek & Newman who developed the first protocol for the network. Roberts engaged Leonard Kleinrock at UCLA to develop mathematical methods for analyzing the packet network technology.

The first computers were connected in 1969 and the Network Control Program was implemented in remote login1970. Further software development enabled remo, file transfer and email. The network expanded rapidly and was declared operational in 1975 when control passed to the Defense Communications Agency.

Internetworking research in the early 1970s by Bob Kahn at DARPA and Vint at Stanford University and later DARPA led to the formulation of the Transmission Control Program, which incorporated concepts from the French CYCLADES  project directed by Louis Pouzin. As this work progressed, a protocol was developed by which multiple separate networks could be joined into a network of networks. Version 4 of TCP/IP was installed in the ARPANET for production use in January 1983 after the Department of Defense made it standard for all military computer networking.

Access to the ARPANET was expanded in 1981, when the National Science Foundation (NSF) funded theComputer Science Network (CSNET). In the early 1980s, the NSF funded the establishment of national supercomputing centers at several universities, and provided network access and network interconnectivity with TCP/IP over the NSFNET from 1986. The ARPANET project was formally decommissioned in 1990, after DARPA partnerships with the telecommunication and computer industry had paved the way for the widespread adoption of the Internet protocol suite as part of the private sector expansion and commercialization of a world-wide network, known as the Internet
