Bandwidth
The difference between the highest and lowest frequencies available for 
network signals. Also synonymous with wire speed, the actual speed of the 
data transmission along the cable.
Collision
A condition in which packets transmitted over the cable interfere with each 
other. Their interference makes both signals unintelligible.
Collision Domain
Single CSMA/CD LAN segment.
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.
