100Base T-An Ethernet standard that provides a 100-Mbps baseband transfer rate over twisted-pair cabling.

10Base 2-An Ethernet standard that specifies a 10-Mbps baseband transmission over thin Ethernet; the maximum transmission distance of any single segment is 185 meters.

10Base 5-An Ethernet standard that indicates a 10-Mbps baseband transmission over a maximum segment length of 500 meters; type of cable used in this standard is called thick Ethernet, or thicknet, and uses RG-8 coaxial cable.

10Base T-An Ethernet standard that specifies a 10-Mbps baseband transmission over twisted-pair cabling; the maximum segment length is 100 meters.

10 Gigabit Ethernet-IEEE 802.3ae standard that uses Ethernet frames in full duplex mode over fiber only. Used extensively in MANs for distances up to 40 km over single-mode fiber.

5-4-3 rule-The rule that stipulates that between stations on a LAN, there can be no more than five network segments connected, the maximum number of repeaters between the segments is four and the maximum number of segments with stations on them is three.

802.2-A standard of the IEEE that specifies the subdivision of the Logical Link Control sublayer from the Media Access Control sublayer. These sublayers are part of the OSI Data Link layer.

802.3-The IEEE standard that defines CSM
