DARPANET

DARPANET (or DARPANet) is a term sometimes used for the ARPANET, the early network from which today's Internet evolved. The Advanced Research Projects Agency (ARPA), the original developers of the early packet-switched network that came to be called the ARPANET, was renamed the (U.S.) Defense Advanced Research Projects Agency (DARPA) in 1971. For this reason, it is often assumed that the ARPANET was then called the DARPANET. However, the Internet Society's own history of the Internet, written by its chief inventors, suggests that it continued to be called ARPANET until ownership was transferred to other groups. See ARPANET for more information.
