CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication 
method employed by Ethernet, Fast Ethernet, or Gigabit Ethernet.
End Station
A workstation, server, or other device that does not forward traffic.
Ethernet
A network communication system developed and standardized by DEC, Intel, and 
Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and 
coaxial cable. The successor IEEE 802.3 standard provides for integration into the 
OSI model and extends the physical layer and media with repeaters and 
implementations that operate on fiber, thin coax and twisted-pair cable.
Fast Ethernet
A 100 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.
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the CSMA/CD 
access method. 
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 802.3u
Defines CSMA/CD access method and physical layer specifications for 
100BASE-TX Fast Ethernet. (Now incorporated in IEEE 802.3-2002.)
IEEE 802.3x
Defines Ethernet frame start/stop requests and timers used for flow control on 
full-duplex links.
