RENAME, and DIR. Unlike external commands, internal
commands can be executed from any drive or directory.
Jumper
A small device that fits over two small pins on a circuit board
to activate a particular function.
Keyboard
A device resembling a typewriter keyboard to enter letters and
numbers to the computer.
Kilobyte (KB)
A unit used to measure storage space in a computer’s memory
or on a disk. One kilobyte equals 1024 bytes.

A subdivision of a physical disk drive, treated by MS-DOS as
though it were a separate physical component of the computer.
A physical disk drive may be divided into several logical drives.
