hard disk: A storage device, also called a fixed disk, composed of a
rigid platter or platters that store information magnetically. Hard
disks hold much more information than diskettes and are used for
long-term storage. Hard disks are not usually user-removable. By
default, the hard disk is referred to as drive C.
hardware: The physical, electronic and mechanical components of a
computer system, including devices such as a display, disk drive,
printer, mouse and processor.
hexadecimal: The base 16 numbering system used by programmers to
represent binary numbers by programmers. Digits above nine are
represented by letters (the 15 digits are 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B,
C, D, E and F). See also binary, decimal.
high-density diskette: A diskette that holds 1.2MB (5.25-inch) or
1.44MB (3.5-inch) of information.
high memory area: The first 64KB of extended memory.
hotkey: A feature in which certain keys in combination with the
Fn
key
alternate system option settings or control system parameters, such
as the battery save mode.
I
icon: A small picture that represents a function, file, or program. In
Windows 95, you can run programs by choosing icons rather than
having to remember the program name and type a command.
input: Information that is put into a computer. This information may
come from a keyboard, pointing device, disk drive or other device.
input/output (I/O): Input and output are two of the three functions that
computers perform (the other is processing). Input/Output
describes the interrelated tasks of providing information to the
computer and providing the results of processing to the user. I/O
devices include keyboards (input) and printers (output). A disk
drive is both an input and an output device, since it can both pro-
vide information to the computer and receive information from the
computer.
instruction: A statement in a computer program that performs a partic-
ular function or task.
