Accessspeed

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 or 80ns (nanoseconds).

Address

A number or name that identifies the location where

information is stored in a computer’s memory.

ASCII

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.

Asynchronous

A method of data transmission in which one machine sends

data, one character at a time, to another machine at variable

intervals that do not need to be synchronized to a timing

device, such as a system clock.
