Access speed

The length of time it takes for an information storage device,

such as memory or a disk drive, to return a piece of data

requested by another device. For example, your computer’s

SIMMs return data requested by the microprocessor at an

access speed of 70ns (nanoseconds).

Address

A number or name that identifies the location where

information is stored in a computer’s memory.

Analog monitor

A monitor that generates, responds to, or acts upon analog

data, such as a VGA monitor. Analog data is transmitted by

varying the voltage levels in a continuous current and can

produce an infinite number of colors or gray shades.

Application program

A software program designed to perform a specific task, such

as word processing or creating spreadsheets. Note that an

application program is different than an operating system,

which controls all the computer’s hardware and software.

ASCll

American Standard Code for Information Interchange. A

standardized numeric coding system for representing

characters, such as numbers, letters, and graphic symbols. Each

of the 256 ASCII codes occupies one byte of storage. All

computers, printers, and programs can use files transmitted in

standard ASCII code. Extended ASCII codes can be used only

by hardware and software designed to interpret them.
