Glossary A adaptor: A device that provides a compatible connection between two units. For example, the computer's internal display adapter receives information from the software and translates it into images on the screen. An adapter can take a number of forms, from a microprocessor to a simple connector: An intelligent adapter (one that is capable of doing some processing) may also be called a controller. alphanumeric: Keyboard characters including letters, numbers and other symbols, such as punctuation marks or mathematical symbols. alternating current (AC): Electric current that reverses its direction of flow at regular intervals. analog signal: A signal whose characteristics such as amplitude and frequency vary in proportion to (are an analog of) the value to be transmitted. Voice communications are analog signals. application: A group of programs that together are used for a specific task such as accounting, financial planning, spreadsheets, word processing and games. ASCII: American Standard Code for Information Interchange. ASCII code is a set of 256 binary codes that represent the most commonly used letters, numbers, and symbols. asynchronous: Lacking regular time relationship. As applied to computer communications, asynchronous refers to the method of transmitting data that does not require a steady stream of bits to be transmitted at regular time intervals. B backup: A copy of a file, usually on a removable disk, kept in case the original file is lost or damaged. binary: The base two number system composed of zeros and ones (off or on), used by most digital computers. The right-most digit of a binary number has a value of 1, the next a value of 2, then 4, 8, 16, and so on. For example, the binary number 101 has a value of 5. See also ASCII. BIOS: Basic Input/Output System. The firmware that controls data flow within the computer. See also firmware. bit: Derived from "binary digit," the basic unit of information used by the computer. It is either zero or one. Eight bits is one byte. See also byte. User's Manual Glossary-3

adaptor:
A device that provides a compatible connection between two
units. For example, the computer's internal display adapter
receives information from the software and translates it into images
on the screen. An adapter can take a number of forms, from a
microprocessor to a simple connector: An intelligent adapter (one
that is capable of doing some processing) may also be called a
controller.
alphanumeric:
Keyboard characters including letters, numbers and other
symbols, such as punctuation marks or mathematical symbols.
alternating current (AC):
Electric current that reverses its direction of flow
at regular intervals.
analog signal:
A signal whose characteristics such as amplitude and
frequency vary in proportion to (are an analog of) the value to be
transmitted. Voice communications are analog signals.
application:
A group of programs that together are used for a specific task
such as accounting, financial planning, spreadsheets, word
processing and games.
ASCII:
American Standard Code for Information Interchange. ASCII code
is a set of 256 binary codes that represent the most commonly
used letters, numbers, and symbols.
asynchronous:
Lacking regular time relationship. As applied to computer
communications, asynchronous refers to the method of transmitting
data that does not require a steady stream of bits to be transmitted
at regular time intervals.

backup:
A copy of a file, usually on a removable disk, kept in case the
original file is lost or damaged.

The base two number system composed of zeros and ones (off or
on), used by most digital computers. The right-most digit of a binary
number has a value of 1, the next a value of 2, then 4, 8, 16, and so
on. For example, the binary number 101 has a value of 5.
