ARCNET (Attached Resource Computer NETwork)

A popular LAN protocol developed by John

Murphy at Datapoint Corporation in 1976, ARCNET was one of the first networking solutions for microcomputers.ARCNET employed coaxial cable to connect host computers, workstations, and peripherals through hubs in a star configuration. ARCNET employed a deterministic token passing bus medium access control (MAC) protocol, operated at signaling speeds up to 2.5 Mbps, and supported as many as 255

devices over link lengths up to 2,000 feet. More recent versions deliver 20 Mbps and 100 Mbps, although they have never been in great demand and are not widely available.ARCnet resembles, but does not adhere to, the IEEE 802.4 specification. ARCNET also is CamelCased as ARCnet. See also 802.4, CamelCase, coaxial cable, deterministic, IEEE, MAC, star, and token passing.
