Appendix A. Glossary
This appendix provides a glossary of useful terms along with their definitions. The terms are listed
alphabetically.
Baud rate
The signaling rate speed of a transmission medium.
Bit
A binary digit; the smallest unit of data in the binary counting system. A bit has a value of either 0 or 1.
BPS - Bits Per Second
A measure of the actual data transmission rate. The BPS rate may be equal to or greater than the baud rate
depending on the modulation technique used to encode bits into each baud interval. The correct term to use
when describing modem data transfer speeds.
Broadcast
A network transaction that sends data to all hosts connected to the network.
Byte
A group of bits, normally eight, which represent one data character.
Channel Bonding
The concept of taking multiple independent serial lines and transporting data over them as if they were one.
For example, two 56 KBPS modem lines can be bonded to form a single 112 KBPS line.
CHAP- Challenge Handshake Protocol
CHAP is a protocol for ensuring secure network access and communications in a point-to-point network
connection.
Client
An intelligent workstation that makes requests to other computers known as servers. PC computers on a
LAN are referred as clients.
DHCP - Dynamic Host Configuration Protocol
DHCP is a service that allows clients on a LAN request configuration information, usually IP host
addresses, from a server. DHCP allows clients to run and operate on an IP-based network without the pre-
assignment of addresses.
DNS - Domain Name Service
A TCP/IP protocol for discovering and maintaining network resource information distributed among
different servers.
Download
In the context of this manual, the process by which a binary hex program is transferred from a client to on-
board FLASH memory.
Ethernet – (Also 10Base-T)
The dominant networking protocol in the industry, characterized by a 10 MBPS (Megabits Per Second)
data rate. A popular form of Ethernet is 10Base-T which is Ethernet running on Unshielded Twisted Pair
(UTP) cable.
Ethernet MAC Address
