Ethernet BasicsHistoryFirst Drawing by Bob Metcalfe

1980 Digital, Intel and XEROX (DIX) publish the specification of a network technology called Ethernet I IEEE 802.3 publishes the first standard that contains parts of the DIX procedure in 1982 1984: DIX passes Ethernet II, since Ethernet I and IEEE 802.3 were incompatible Today‘s components are based on IEEE 802.3
