2GLOSSARY

Class I A type of 100BASE-T repeater with internal delay such that only one repeater or stack may exist between any two end stations within a single collision domain when two maximum-length copper cable segments are used.

Class II A type of 100BASE-T repeater with internal delay such that two repeaters or stacks may exist between any two end stations within a single collision domain when two maximum-length copper cable segments are used.

Collision A condition that results from concurrent transmissions from multiple sources within a single collision domain.

Collision domain A single CSMA/CD network. If two or more Media Access Control (MAC) sublayers are within the same collision domain and both transmit at the same time, a collision will occur. MAC sublayers separated by a repeater are in the same collision domain; MAC sublayers separated by a bridge, router, or switch are within different collision domains.

Ethernet A local area network standard defining a physical medium and its method of placing data, or packet signaling, on a cable. Access to the cable is based on CSMA/CD (carrier sense multiple access with collision detection).

Fast Ethernet A 100 Mbps technology based on the Ethernet CSMA/CD network access method.

FDDI Fiber Distributed Data Interface. The local area networking standard that provides high bandwidth for interconnecting computers and peripheral devices using a fiber-optic medium in a ring configuration.

The FDDI specification is made up of standards that correspond to the IEEE OSI model layers (on the physical and data link levels). These standards specify the physical interfaces, functions, and operations needed to support interoperability between devices.

Fiber-optic cable Cable consisting of a glass center, cladding, a buffer layer, strength members, and a cable sheath. The glass center supports the transmission of light signals.
