The ARPANET was the first widespread, packet switched, network of heterogeneous
computers. The ARPANET began operations in late 1969, was decommissioned
in 1989, and was the basis for the modern Internet. The foundation of the
network was the subnet of Interface Message Processor (IMPs), which were
small, identical processors at each node of the network that performed
the packet switching.
