IEEE 802 standards

A set of network standards developed by the IEEE. They include:

  • IEEE 802.1: Standards related to network management.
  • IEEE 802.2: General standard for the data link layer in the OSI Reference Model. The IEEE divides this layer into two sublayers -- the logical link control (LLC) layer and the media access control (MAC) layer.The MAC layer varies for different network types and is defined by standards IEEE 802.3 through IEEE 802.5.
  • IEEE 802.3: Defines the MAC layer for bus networks that use CSMA/CD. This is the basis of the Ethernet standard. Also see the Ethernet Designations chart in the Quick Referencesection of Webopedia.
  • IEEE 802.4: Defines the MAC layer for bus networks that use a token-passing mechanism (token bus networks).
  • IEEE 802.5: Defines the MAC layer for token-ring networks.
  • IEEE 802.6: Standard for Metropolitan Area Networks (MANs).
