Ethernet

Xerox PARC links office computers on a shared coaxial cable at 2.94 Mbit/s.

Robert Metcalfe and David Boggs designed Ethernet at Xerox PARC in 1973, inspired by Hawaii's ALOHAnet radio network. Standardised in 1983, it became the universal local network, scaling from megabits to 400 gigabits per second.
