Origin and Development of Internet

The Internet has its origins in a network called the 'ARPA net, developed in the early 1970s by the Advanced Research Projects Agency (ARPA) in the US. It was first used for the transfer of intelligence within the US Department of Defence, but, later on it was adopted by the academic community to build an academic network for information exchange. By late 1980s; access to the Net was open to the general public, as network technology introduced client server architecture and ethernet local area networks, supporting end-user access to networks. 

By mid 1990s, the Internet was made up of over 60,000 networks. Basic descriptions of the Internet generally start by identifying it as a network of networks, run cooperatively with a minimum of supervision, where the participating networks agree on the common protocols and rules. Nobody, therefore, is officially incharge or controls the Internet.
