cooling method: The method used to keep the computer's internal tem
perature at an operating level that is safe for the computer. There
are two methods available: using a cooling fan or reducing pro
cessing speed. The fan is the better choice when you are running
the computer from a wall outlet, but reducing processing speed
saves power when you are using the battery.
cursor: A symbol that indicates the current position on the screen. The
shape of the cursor varies, depending on the program you're using
and what you're doing.
data: Information that a computer can process. The word "data" is
actually plural for "datum," meaning a single piece of information.

bits used to represent a character. If data bits = 7, the computer can
generate 128 unique characters, if data bits = 8, the computer can
generate 256 unique characters.

Computers, in contrast, generally use binary or hexadecimal num
bering systems. See also binary, hexadecimal.

age device. Synonymous with erase.

include the hard disk and screen. External devices you can connect
to the computer include a monitor, printer and port replicator.

device such as the screen, CD-ROM drive or printer. The operating
system loads many device drivers when you turn on the computer.
