Glossary

 

 

 

10BaseT

 

The 10-Mbps baseband Ethernet specification that uses two pairs of twisted-pair

 

 

cabling (Category 3 or 5); one pair for transmitting data and the other for receiving

 

 

data.

 

 

 

Analog

 

An electrical circuit that is represented by means of continuous, variable physical

 

 

quantities (such as voltages and frequencies), as opposed to discrete representations

 

 

(like the 0/1, off/on representation of digital circuits).

 

 

 

ARP

 

Address Resolution Protocol is a protocol for mapping an Internet Protocol address (IP

 

 

address) to a physical machine address that is recognized in the local network.

 

 

 

AT&T 5ESS

 

A digital central office switching system made by AT&T.

 

 

 

Authenticity

 

Proof that the information came from the person or location that reportedly sent it. One

 

 

example of authenticating software is through digital signatures.

 

 

 

Backbone

 

A high-speed line or series of connections that forms a major pathway within a

 

 

network.

 

 

 

Bandwidth

 

This is the capacity on a link usually measured in bits-per-second (bps).

 

 

 

Bit

 

A Binary Digit (either a one or a zero). A single digit number in base-2. A bit is the

firmware, changing the console port speed and viewing product-related information.

 

 

 

Bridging

 

Bridging provides LAN to LAN frame forwarding services between two or more LANs.

 

 

Frames from one LAN are forwarded across a bridge to a connected LAN, although

 

 

filtering can be employed to selectively forward frames. Bridging works similar to the

 

 

way repeaters work except that bridges forward frames based on their MAC (Medium

 

 

Access Control) addresses which are hardware-level addresses of NICs (Network

 

 

Interface Cards).

 

 

 

Byte

 

A set of bits that represent a single character. There are 8 bits in a Byte.

 

 

 

CDR

 

Call Detail Record. This is a name used by telephone companies for call-related

CHAP

 

Challenge Handshake Authentication Protocol is an alternative protocol that avoids

 

 

sending passwords over the wire by using a challenge/response technique.

 

 

 

Client

 

A software program that is used to contact and obtain data from a Server software
