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.
Crossover Port
Twisted-pair port with a built-in wiring crossover.
End Station
A workstation, server, or other device that does not act as a
network interconnection.
