Input/output (I/O) port See Port. Interface A physical or software connection used to transmit data between equipment or programs. Internal command An MS-DOS command that is stored in the command processor of the operating system; it is not a separate program file. This means that you can execute an internal command without specifying a pathname. Examples include COPY, DEL, 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. Logical disk drive 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. Glossary 9
