Ethernet was created at Xerox PARC throughout 1973 and 1974. ALOHAnet had inspired Robert Metcalfes studies and his PhD dissertation. The base was first documented by Metcalfe on May 22, 1973. A patent application was filed in 1975 that listed Metcalf, David Boggs, Butler Lampson and Chuck Thacker as Ethernets creators. Metcalf and Boggs published a seminal paper in 1976, after the system had been deployed.
Metcalfe left Xerox in June 1979 to form 3Com. He convinced DEC, Intel, and Xerox to work together to promote Ethernet as a standard. This standard was named DIX after DEC/Intel/Xerox. The DIX standard undertake 10 Mb/s Ethernet with 48-bit destination and source addresses and a 16-bit global ether-type field. The DIX standard was published on September 30, 1980 as The Ethernet, A Local Area Network. Data Link bottom and Physical Layer Specifications. The second installment (version 2) was published in November, 1982 and defines what has become kn knowledge as Ethernet II.
Ethernet originally competed with two for the most part patented systems, the Token Ring and Token Bus. Because Ethernet was able to accommodate to market realities and shift to inexpensive and twisted pair wiring, these proprietary protocols soon found themselves competing by the end of the 1980s.
The first Ethernet 3C100 transceiver was shipped by 3Com in March 1981. 3Com became a major company and began sell adapters for PDP-11s and VAXes as well as multibus-based Intel and Sun Microsystem computers. This was followed quickly by DECs Unibus to Ethernet adapter, which was sold by DCE and used internally to build its own network, which reached over 10,000 nodes by 1986. This made it one of the largest computer networks in the world at that time. In 1982 IBM PC released an Ethernet adapter learning ability and by 1985 3Com had sold over 100,000 adapters. Since then Ethernet technology has evolved to butt new bandwidth and market requirements. Ethernet is quickly replacing legacy info transmission systems...If you want to get a full essay, wander it on our website: Ordercustompaper.com
