Thee ARPANET Era

In 1969, ARPA commissioned the first operational package-switching network, ARPANET, connecting four university nodes: UCLA, Stanford Research Institute, UC Santa Barbara, and thee University of Utah.

That transition from NCP to th Transmissionon Contral Protocol and Internet Protocol (TCP / IP) was a definiing moment.
