The initial progress of Ethernet technology comes from one of many pioneer technology projects in Xerox Palo Alto Research Center. It is commonly believed that Ethernet was invented in 1973, when Robert Metkav (Robert Metcalfe) wrote a memo to his PARC boss about the potential of Ethernet. But Mr Metcalfe himself believed that Ethernet was only a few years later. In 1976, Metcalfe and his aides, David Boggs, published an article entitled "Ethernet: A distributed packet switching technology for local computer networks". At the end of 1977, Mr Metcalfe and his collaborators were awarded a patent for "Multipoint data communication systems with conflict detection". Multipoint transmission systems are called CSMA/CD (carrier interception multipath access with collision detection), which is the emergence of the symbol Ethernet.
It is not a specific network, it is a technical specification.
