IEEE 802.3 is an IEEE standard that defines a set of physical layer and media access control sublayer of the data link layer of wired Ethernet standard. IEEE 802.3 is a majority of technology Local Area Network (LAN), but some of them are technology Wide Area Network (WAN).
IEEE 802.3 is also a technology that supports the IEEE 802.1 network architecture.
Etthernet DIX and IEEE 802.3 [edit]
Original Ethernet specification (which is referred to as "Experimental Ethernet") was developed by Robert Metcalfe in 1972 and patented in 1978 and was based on part of a wireless protocol ALOHAnet. Indeed, Experimental Ethernet is not used anymore at this time, but may be considered as the Ethernet protocol by some. Ethernet is known now used outside of Xerox is DIX Ethernet. However, because the DIX Ethernet also developed from the Experimental Ethernet, and a growing number of standards that was developed based on the DIX Ethernet technology, the technical community has been assume that everything is Ethernet. Therefore, the use of the term Ethernet can also be used to refer to all networks that use media functions and standardized as follows:
IEEE 802.3 is a frame format that is the result of a merger of the IEEE 802.2 and IEEE 802.3, and consists of a header and a trailer IEEE 802.3 and IEEE 802.2 header.
