configuration consists of a computer with one diskette drive, one
hard disk drive, and a monitor, connected to a printer.
Control code
A command (generated when you hold down Ctrl and press
another key on the keyboard) that instructs the computer to
perform a specific function.
Conventional memory

MS-DOS
and application programs. Also called base memory or main
memory.

of high speed (25 MHz). See also Automatic speed.
