[70] [71] [72] The first permanent ARPANET link was established on 21 November 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute. By 5 December 1969, the initial four-node network was established. Elizabeth Feinler created the first Resource Handbook for ARPANET in 1969 which led to the development of the ARPANET ...
Hence, the literal first message over the ARPANET was "lo". About an hour later, having recovered from the crash, the SDS Sigma 7 computer effected a full "login". [20] [23] The first permanent ARPANET link was established on November 21, 1969, between the Interface Message Processor (IMP) at UCLA and the IMP at the Stanford Research Institute ...
The first heterogeneous computer network was implemented in 1973, connecting the ARPANET to University College London. This evolved into SATNET. The first Transmission Control Program demonstration, linking SATNET, the ARPANET, and PRNET took place on November 22, 1977.

The first permanent ARPANET link was established on November 21, 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute.
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. [1] [2] [3] An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. [4]
October 29 – The first ARPANET message is sent, between computers at the University of California, Los Angeles (UCLA) and Stanford Research Institute. [ 6 ] November 21 – The first permanent ARPANET link is established, between Interface Message Processors at UCLA and Stanford.
The connection between the interface message processors at the University of California, Los Angeles (UCLA), and the Stanford Research Institute (SRI, in Menlo Park, California) was made permanent, creating the first link of ARPANET, the Advanced Research Projects Agency Network. [80]
[183] [45] [184] In 1969, the NPL, followed by the ARPANET, were the first two networks to use packet switching. [185] [44] By 1976, 12 computers and 75 terminal devices were attached, [186] and more were added until the network was replaced in 1986. NPL was the first to use high-speed links. [187] [188] [189]
