Collision
A condition in which packets transmitted over the cable
interfere with each other. Their interference makes both signals
unintelligible.
Crossover Port
An RJ-45 port which crosses the receive and transmit signals
internally so it can be connected with straight-through twisted-
pair cable to a workstation, server or any other device having a
straight-through port.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the
communication method employed by Ethernet and Fast
Ethernet.
End Station
A workstation, server, switch, bridge or router.
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.
