802.3 - Computer Definition
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.
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.
