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 non-alphabet keys.
card: A circuit board that you can plug into a slot inside the Apple IIe to expand the
computer's memory, enhance its video capabilities, or give it the means to communicate with a
peripheral device like a printer or a modem.
CAT: A ProDOS command that you can use to examine the contents of a disk. CAT is short for
catalog.
catalog: A list of all the files on a disk. Sometimes called a directory.
Catalyst: A program manager produced by Quark.
characters: Letters, numbers, and other symbols used to communicate with a computer.
character generator ROM: The integrated circuit responsible for printing characters on the
screen.
chip: A small wafer containing thousands of microscopic components.
circuit board: A collection of integrated circuits (chips) on a board.
click: The act of pressing the mouse button. You click the mouse when you want to select
something from a list in a mouse-driven program.
clock card: An interface card that keeps time. A clock card can work with software to control
when files are sent to a remote computer, when a given appliance is turned on or off, and it
can mark the time and date a file was last revised.
COBOL: An acronym for Common Business Oriented Language. A business-oriented programming
language especially suited to applications involving large amounts of data.
code: To write a program. Can also refer to the lines of the program.
column: A way of designating the width of the computer's display. A column is one character
wide. The standard Apple IIe can display 40 columns of characters. An Apple IIe with an
80-column text card can display 80 columns of characters.
command: A word or character that causes the computer to do something.
communications software: Programs that make it possible to exchange information with other
computers.
compiler: A computer program that translates a language, such as Pascal, into a language the
computer can understand. A compiler translates the entire program just once. Compare
interpreter.
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 repetitious tasks.
computer-aided design: Software for creating three-dimensional drawings.
computer-aided instruction: Learning something (math, history, home economics, or anything
else) with the help of a computer program.
