This network was set up for the military purpose. It began in a modest way with one computer in California and three in Utah. The primary goal of ARPANET was to allow multiple users to send and receive information simultaneously over the same communication path. The network operated with a technique called packet switching using TCP. Later, to share the software and hardware resources, the military allowed universities to join the network from where the students caught up with it and developed much of the software, giving birth to the now so very popular internet. This ARPANET was divided into two parts MILNET and ARPANET. MILNET was used for military related sites and ARPANET for non-military sites. These two networks were connected together by using IP Internet Protocol. The combine set op protocol is called TCP/IP. During the 1970’s networks like the BITNET and the USENET came into being. Around 1980’s NSFNET (National Science Foundation Network) was created. This growing web was the birth of the network.
