Byte: A basic unit of data manipulated by the computer, usually eight bits. The space required to store a single printed character.

Cable: The transmission link between devices in a computer system.

Cache, cache memory: A fast memory buffer for holding frequently called data.

Compact Disk of CD: A digital disk from which data is read by a special laser. The laser reads binary data as ‘0’s and ‘1’s by distinguishing between microscopic flat and pitted dots on the surface of the disk.

Circuit boards: An insulated card that holds circuits, electronic components and connectors that comprise or drive other computer components such as a communication port, video, a scanner, etc.

Click: To quickly press and release the button on a computer mouse or similar device to place the cursor at a particular position on a document or to make a selection.

COBOL (Common Business Oriented Language): A structured computer programming language for business applications that uses a vocabulary of familiar English words and phrases.

Cold Boot: Restarting a computer that is completely shut down.

Computer Literate: Having a working knowledge of the way in which a computer operates and of at least some of the most popular software programs.

Computer Security: The process of protecting a computer, computer network, or computer programs and data from access by unauthorized persons.

CPS: Characters Per Second; a measure of the speed of an impact printer.

CRT (Cathode-Ray Tube): A type of picture tube used as a computer monitor screen. The image is created by firing beams of electrons at “phosphors” that coat the inside of the tube; the phosphors, when struck, emit a burst of light with a “refresh rate” of 60 times per second or greater, the burst appear to be a steady image.

Dedicated: Set aside for a specific purpose, such as an area in computer memory that us reserved for certain utilities or a transmission line reserved for network communication.

Hertz or Hz: One cycle per second.

Hexadecimal: A numbering system in base sixteen used in computer notation. Hexadecimal digits are represented as ‘0’ through ‘9’ and ‘A’ through ‘F’.

High Level Language (HLL): A programming language in which the commands and syntax are somewhat similar to a spoken language. Working in such a language precludes the need for the programmer to have a knowledge of machine language. Writing code for complex program routines is more efficient in a high level language as a single command may replace several commands machine language.

Integrated Circuit (IC): An electronic device that contains number of circuit elements and inter connections.

K (Kilo): One thousand. In binary numbers, used to express 1024.

KB, kb (Kilobyte): One thousand bytes or more specifically, 1024 bytes Kilocycle (kc).

Kilohertz: Kilohertz; one thousand cycle per second.

Kerning: Proportional spacing between typeset characters.
