An IEEE standard for a CSMA/CD local area network access method, which is used in Ethernet, the most common LAN technology. Following are the major Ethernet standards. See 10Base-T, 100Base-T, Gigabit Ethernet and CSMA/CD.IEEE SpeedStandard (Mbps) Common Name 802.3i 10 Ethernet 802.3u 100 Fast Ethernet 802.3z 1000 GigE over Fiber 802.3ab 1000 GigE over Copper 802.3ae 10000 10 Gig over Fiber 802.3bm 40000 40 Gig over Fiber 802.3bm 100000 100 Gig over Fiber 802.3bp 1000 GigE for vehicles 802.3bs 200000 200 Gig over Fiber 802.3bs 400000 400 Gig over Fiber 802.3bv 1000 GigE over Fiber.
The IEEE standard that defines the carrier sense multiple access (CSMA) method of medium access control (MAC), and Physical Layer specifications.Although the term is commonly used interchangeably with Ethernet, 802.3 actually is a variation on the original Ethernet standard. (Note: Project 802 took its name from the fact that it was established in the year 1980, and the month 2, i.e., February.) See also, CSMA, Ethernet, IEEE, LAN, MAC, and standard.
