GLOSSARY

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.
