IEEE 802.3 - Networking
IEEE LAN protocol that specifies an implementation of the physical layer and the MAC sublayer of the data link layer. IEEE 802.3 uses CSMA/CD access at a variety of speeds over a variety of physical media. Extensions to the IEEE 802.3 standard specify implementations for Fast Ethernet. Physical variations of the original IEEE 802.3 specifications include 10Base2, 10Base5, 10BaseF, 10BaseT, and 10Broad36. Physical variations for fast ethernet include 100BaseT, 100BaseT4, and 100BaseX.
