ARPANet

The Advanced Research Projects Agency Network formed in 1969 to connect the Department of Defense (DOD) with institutions conducting major defense contract research. The network linked super computers in major research universities with the DOD. This is credited with being the first academic computer network and is considered the "mother" of the Internet. In the 1980s, ARPANet split into two networks called ARPANet and MILNet (for unclassified military research). An interconnection with the DOD Advanced Research Projects Agency (DARPA) led to a set of networks called DARPA Internet that later became referred to as just the Internet. (See also Internet )
