ARPANET, in computer science, a network of about 60,000 medium-to-large-scale computers established in the 1960s and developed by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense as a vehicle for enabling universities and research organizations to exchange information freely. ARPANET, although part of the Department of Defense, is not a classified government or military network. In 1990 ARPANET was replaced by the National Science Foundation Network (NSFNET) to connect its supercomputers to regional networks. NSFNET now operates as the high-speed backbone of the Internet.
