Glossary

Mid-range computer: A term coined by IBM

referring to any of their Advanced Business

Systems computers. This product line was

originally called their mini-computers, but as

the number of supported users approached

mainframe capabilities, the term "mid-range"

caught on.

Mnemonics: A term assigned to a complex

idea, value, or list of information which is

found to be representative of that information.

Computer commands are almost entirely

mnemonics. Mnemonics are used as memory

aids for people.

Modem: A communications device that

enables a computer to transmit information

over a telephone line. It converts the

computer's digital signals into analog signals

to send over a telephone line and converts

them back to digital signals at the receiving

end. Modems can be internal and fit into an

expansion slot, or external and connect to a

serial port.

Modulation: The process of encoding

information from one signal (called the

source) into another (called the carrier) by

modifying some characteristic(s) of the carrier.

It is often used in telecommunications when

one type of signal must be converted for

transmission over an otherwise incompatible

medium.

Multiplexer (mux): A device that merges

several signals into one composite signal for

transmission over a single medium or

channel. A de-multiplexer (usually built into a

mux) reverses the process at the receiving

end.

NAK (Negative Acknowledgment):

Communications code used to indicate that a

message was not properly received, or that a

terminal does not wish to transmit. Contrast

with ACK.

Network: A group of computers connected

by cables or other means and using software

that enables them to share equipment, such

as printers and disk drives to exchange

information.

Node: Any point within a network which has

been assigned an address.

Normal mode: In modem operation, refers to

a mode of operation without error correction

active.

Off-hook: The condition of a device which

has accessed a phone line (with or without

using the line). In modem use, this is

equivalent to a telephone handset being

picked up. Dialing and transmission are

allowed, but incoming calls are not answered.

On-Hook: The condition of a device which

has not accessed a phone line. In modem

use, this is equivalent to a telephone handset

that has not been picked up. In other words,

it can receive an incoming call.

Parameter:

1. A "place holder" in a command which

should be substituted with useful information.

2. The list of acceptable values for a given

option or command. In UNIX, the generic

command should be typed in as Stty/s 9600.

Where "Stty" is the command, "s" is the speed

switch, and "9600" where s=1200-115,200

bps.

Parity bit: An extra bit attached to each byte

of synchronous data used to detect errors in

transmission.

other electronic components. The board is

"printed" with electrically conductive pathways

between components. The main PCB in a

system is called a motherboard and the

smaller PCBs that plug into the slots in the

motherboard are called daughter boards or

cards.

PCMCIA (personal computer memory card

international association): An organization

of U.S. and Japanese companies set up to

standardize memory cards and other

architecture-independent expansion devices.

These cards are typically used in laptop

computers.
