View source for Network Control Program (ARPANET)

'''Network Control Program''' is the name for the software on the [[host]]s attached to the [[ARPANET]] which implemented the [[protocol suite]] of the early ARPANET, [[Network Control Protocol]] as it later came to be called. (See [https://elists.isoc.org/pipermail/internet-history/2022-June/008155.html here] for more about the evolution of these names.) The term did not later, usually, include the [[application]]s (such as 'User [[Telnet]]').
