hard disk: A storage device composed of a rigid platter or platters that
can be magnetically coded with data. Hard disks hold much more
information than diskettes and are used for long-term storage of
programs and data. The primary (or only) hard disk in a computer is
usually fixed, but some computers have secondary hard disk that are
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 screen, disk drive,
printer, pointing device and processor.
hexadecimal: The base-16 numbering system used by programmers to
represent binary numbers. Digits above 9 are represented by letters
(the 15 digits are 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F). Two
hexadecimal digits are equivalent to the eight bits in a byte. For
example, F1 in hexadecimal is equivalent to 11110001 in binary.
