5 Appendix B: Glossary
10BaseT - An Ethernet standard that uses twisted wire pairs. 100BaseTX
- IEEE physical layer specification for 100 Mbps over two pairs of Category
5 UTP or STP wire.
1000BASE-T - A 100 Mbps technology based on the Ethernet/CD network
access method. Provides half-duplex (CSMA/CD) and full-duplex 1000
Mbps Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-
568-A. Topology rules for 1000BASE-T are the same as those used for
100BASE-T. Category 5 link lengths are limited to 100 meters by the
ANSI/TIA/EIA-568-A cabling standard. Only one CSMA/CD repeater will be
allowed in a collision domain.
Adapter - Printed circuit board that plugs into a PC to add capabilities or
connectivity to a PC. In a networked environment, a network interface card
(NIC) is the typical adapter that allows the PC or server to connect to the
intranet and/or Internet.
American National Standards Institute (ANSI) - The coordinating body
for voluntary standards groups within the United States. ANSI is a member
of the International Organization for Standardization (ISO).
American Standard Code for Information Interchange (ASCII) - This is
the code that most computers use to represent displayable characters. An
ASCII file is a straightforward text file without special control characters.
Asymmetrical Digital Subscriber Line (ADSL) - A new standard for
transmitting at speeds up to 7 Mbps over a single copper pair.
Auto-negotiate - To automatically determine the correct settings. The
term is often used with communications and networking. For example,
Ethernet 10/100 cards, hubs, and switches can determine the highest
speed of the node they are connected to and adjust their transmission rate
accordingly.
Backbone – The part of a network that connects most of the systems and
networks together and handles the most data.
Bandwidth – 1. Measure of the information capacity of a transmission
