To prepare a new disk (or an old one you want to reuse) so that
it can store information. Formatting divides a disk into tracks
and sectors and creates addressable locations on it.
Graphics
Lines, angles, curves, and other nonalphanumeric data.
Hard disk
The enclosed unit used to store large amounts of data. Unlike a
diskette, it is fixed in place. It can process data more rapidly
and store many more files than a diskette. Also called fixed disk.
Hardware

monitor, printer, keyboard, or CPU.

single- or double-density diskettes. A high-density
diskette can store 1.2MB of data. A high-density
diskette can store 1.44MB of data.

See Port.

A physical or software connection used to transmit data
between devices or programs.
