ARPANET

The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first computer networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (now DARPA) of the United States Department of Defense.[1] Building on the ideas of J. C. R. Licklider, Bob Taylor initiated the ARPANET project in 1966 to enable resource sharing between remote computers.[2] Taylor appointed Larry Roberts as program manager. Roberts made the key decisions about the request for proposal to build the network.[3] He incorporated Donald Davies' concepts and designs for packet switching,[4][5] and sought input from Paul Baran on dynamic routing.[6] In 1969, ARPA awarded the contract to build the Interface Message Processors (IMPs) for the network to Bolt Beranek & Newman (BBN).[7][8] The design was led by Bob Kahn who developed the first protocol for the network. Roberts engaged Leonard Kleinrock at UCLA to develop mathematical methods for analyzing the packet network technology... Version 4 of TCP/IP was installed in the ARPANET for production use in January 1983 (starting Jan01'1983) after the Department of Defense made it standard for all military computer networking. https://en.wikipedia.org/wiki/ARPANET
