cancel an action.
byte: A sequence of eight bits that represents an instruction, a letter, a number, or a
punctuation mark.
C: A programming language that makes it relatively easy for programmers to adapt applications
designed for one type of computer for use on others.
CAI: See computer-aided instruction.
Caps Lock: A key that you can lock into place so that subsequent letters you type will come out
capitalized. Caps Lock doesn't affect nonalphabet keys.
card: A circuit board that you can plug into a slot inside the Apple IIgs to expand the
computer's memory or give it the means to communicate with a hard disk, a braille printer, or
some other peripheral device.
carriage return: Abbreviated CR. A nonprinting character that tells the computer or printer to
end a line of text and start a new one. It's used to end paragraphs. Even though you can't see
them, you can delete carriage returns the same way you delete other characters.
case: The outer covering of the computer.
catalog: See directory.
CD ROM Player: Stands for compact disc. A device that reads information from a
super-high-capacity disc (550 megabytes and more) by using laser technology. Like a phonograph
record, you can play the disc, but you can't record information on it.
cell: The intersection of a row and a column in a spreadsheet. A cell can hold a number, label,
function, or formula.
character: A letter, number, or other symbol.
character generator: The integrated circuit responsible for printing characters on the screen.
character set: The letters, numbers, and symbols that can be generated by pressing keys on a
keyboard.
chip: A small silicon wafer containing thousands of microscopic components. See also integrated
circuit.
choose: To pick a command from a menu. Usually you do this after selecting something for the
Apple IIgs to act on.
circuit board: See main circuit board.
circuitry: A network of wires, chips, resistors, and other electronic devices and connections.
Clear: A key on the numeric keypad. Pressing Clear works the same as pressing Control-X.
Pressing Control-X while writing a BASIC program cancels the line you're typing.
click: To position the pointer on something, then press and quickly release the mouse button.
clip art application: Electronic pictures that you can clip from one disk or document into
another. You can buy disks of clip art and use these professional-quality drawings to
illustrate your documents.
