Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the
CSMA/CD access method.
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the
CSMA/CD access method.
Full Duplex
Transmission method that allows two network devices to transmit and
receive concurrently, effectively doubling the bandwidth of that link.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
Defines carrier sense multiple access with collision detection (CSMA/CD)
access method and physical layer specifications.
IEEE 802.3ab
Defines CSMA/CD access method and physical layer specifications for
1000BASE-T Gigabit Ethernet. (Now incorporated in IEEE 802.3-2002.)
IEEE 802.3af (PoE)
An IEEE standard for providing Power over Ethernet (PoE) capabilities.
When Ethernet is passed over copper cable, two twisted pairs are used for
data transfer, and two twisted pairs are unused. With PoE, power can
either be passed over the two data pairs or over the two spare pairs.
IEEE 802.3u
Defines CSMA/CD access method and physical layer specifications for
100BASE-TX Fast Ethernet. (Now incorporated in IEEE 802.3-2002.)
