ARPANET
ARPANET
ARPANET (/'ɑːrpənɛt/), short for Advanced Research Projects Agency Network, was an early packet-switching network and the first network to implement the protocol suite TCP/IP. Both technologies became the technical foundation of the Internet.
Etymology
The term ARPANET is an acronym that stands for Advanced Research Projects Agency Network. The name comes from its founder, the Advanced Research Projects Agency (ARPA), which was a research funding organization within the United States Department of Defense (DoD).
History
The ARPANET project led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks. ARPANET was established by Robert Taylor and Lawrence Roberts of the Information Processing Techniques Office (IPTO) within ARPA.
