Format
To prepare a new disk (or an old one you want to reuse) so that
the data you store on it can be used by your operating system.
Formatting divides a disk into tracks and sectors and creates
addressable locations where your operating system can find
your data.
Graphics
Screen or file data such as lines, angles, and curves. A graphics
program creates images by joining individual pixels on the
screen to represent virtually any shape desired.
Hard disk
An encased storage device containing one or more disk platters
used to store large amounts of data. Unlike a diskette, a hard
disk is fixed in place. It can process data more rapidly and store
many more files than a diskette. Also called fixed disk.
Hardware
Any physical component of a computer system, such as a
monitor, printer, keyboard, main system board, disk drive, or
CPU.
Hexadecimal
A base-16 numbering system frequently used by programmers
to represent the binary numbers used by the computer. Any
decimal number between 0 and 255 can be expressed by a
two-digit hexadecimal number consisting of the numbers 0
through 9 and the letters A through F. Hexadecimal numbers
are usually followed by the letter H (or h) to differentiate them
from decimal numbers.
