GLOSSARY

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.

Class I Repeater

Fast Ethernet repeater that is principally used to connect different physical signaling systems (e.g., 100BASE-TX, 100BASE-FX) and that has an internal delay such that only one repeater of this type can reside within a single collision domain when maximum cable lengths are used.

Class II Repeater

Fast Ethernet repeater that typically supports a single physical signaling system (e.g., 100BASE-TX, or 100BASE-FX) and that has a smaller internal delay so that two such repeaters can reside within a single collision domain when maximum cable lengths are used.

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

Carrier Sense Multiple Access/Collision Detect is the communication method employed by Ethernet and Fast Ethernet.

End Station

A workstation, server, or other device that does not act as a network interconnection.
