2 Glossary
Collision
A condition in which two packets transmitted over a medium interfere
with each other. This interference makes both unintelligible.
Configuration
The way to set up a computer, server, or local area network.
Connection
A logical binding between two or more users of an interconnection
service.
Daisy-Chain Port
An MDI RJ-45 port used to cascade compatible devices in a daisy-
chain configuration using straight-through twisted-pair cable. To
cascade to another device, you may either use the daisy-chain port, or
cascade the two devices by running crossover cable between MDI-X
station ports on both devices.
Ethernet
A network communication system developed and standardized by
DEC, Intel, and Xerox, using baseband transmission, CSMA/CD
access and 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 implementa-
tions that operate on fiber optics, baseband, and twisted-pair.
Fiber Optic Cable
Communications cable with a glass filament in the center, covered
with several layers of sheathing for strength and insolation. Signals
are transmitted along the glass filament in the form of light pulses.
IEEE 802.3 Standard
Standard for the physical and electrical connections in local area
networks developed by the IEEE. The IEEE 802.3u standard covers
these same issues for 100 Mbps networks.
