communications software: An application that makes it possible to exchange information with other computers.

compatibility: The condition under which devices can work with each other.

composite: A video signal that includes both display information and the synchronization (and other) signals needed to display it. There are monitor ports on the Apple IIGS for an NTSC composite monitor (one that accepts signals that conform to the standards set by the National Television Standards Committee) and for an analog RGB monitor.

computer: A machine that processes words and numbers faster than a food processor can slice potatoes. Not particularly creative or intuitive, but very good at repetitive tasks.

computer-aided Instruction: Abbreviated CAI. Learning math, history, home economics, or almost anything else with the help of a computer application.

computer system: A collective term for the Apple IIGS and everything attached to it.

configuration: A general-purpose computer term that can refer to the way you have your computer set up (that is, the devices you have attached to it) or to the way you have your computer set up to send information to a printer, a modem, or some other peripheral device.

connect time: The amount of time you spend accessing an information service.

construction set: An application that lets you design and build things like games and machines.

contrast knob: A control on your video display that lets you adjust the contrast between the light and dark on the screen.

Control: A key on the Apple IIGS keyboard that, when pressed in conjunction with another key, makes the other key behave differently. It controls the operation of other keys. Compare Open Apple.

controller card: An interface card that tells your Apple IIGS how to work with one or two disk drives.

Control Panel Program: A program built into the Apple IIGS that lets you set the time of the built-in clock and tailor certain aspects of your computer system to suit your individual preferences—like the color of text and background on the screen, the volume of the built-in speaker, and more.

co-processor: A microprocessor on a card that overrides or works with the microprocessor on the main circuit board.

copy-protect: To prevent someone from duplicating the contents of a disk. Compare write-protect.

courseware: Educational software.

CP/M: Stands for Control Program for Microprocessors. An operating system that works with the Z80 microprocessor.

CR: See carriage return.

cursor: A blinking underline, rectangle, or other symbol that marks your place on the screen. It shows you where your next action will take place. Compare pointer.

cut: To remove text or pictures from a document by using the Cut command. The most recent "clipping" is stored-on the Apple IIGS's Clipboard so you can "paste it" somewhere else if you want.

cut and paste: To move something from one place in a document to another. It's the computer equivalent of using scissors to clip something and glue to paste the clipping somewhere else.
