The Internet is a worldwide network of thousands of computers and computer networks. It is a public, voluntary, and cooperative effort between the connected institutions and is not owned or operated by any single organization. The Internet and Transmission Control Protocols were initially developed in 1973 by American computer scientist Vinton Cerf as part of a project sponsored by the United States Department of Defense Advanced Research Projects Agency (ARPA) and directed by American engineer Robert Kahn.
The Internet began as a computer network of ARPA (ARPAnet) that linked computer networks at several universities and research laboratories in the United States. The World Wide Web was developed in 1989 by English computer scientist Timothy Berners-Lee for the European Organization for Nuclear Research (CERN).
"The design of the Internet was done in 1973 and published in 1974. There ensued about 10 years of hard work, resulting in the roll out of Internet in 1983. Prior to that, a number of demonstrations were made of the technology – such as the first three-network interconnection demonstrated in November 1977 linking SATNET, PRNET and ARPANET in a path leading from Menlo Park, CA to University College London and back to USC/ISI in Marina del Rey, CA." . – Vinton Cerf explains the timing:
Internet, interconnection of computer networks that enables connected machines to communicate directly. The term popularly refers to a particular global interconnection of government, education, and business computer networks that is available to the public. There are also smaller internets, usually for the private use of a single organization, called intranets.
Internet technology is a primitive precursor of the Information Superhighway, a theoretical goal of computer communications to provide schools, libraries, businesses, and homes universal access to quality information that will educate, inform, and entertain. In early 1996, the Internet interconnected more than 25 million computers in over 180 countries and continues to grow at a dramatic rate.
