communication port. Mice, printers, modems and other peripheral devices can be connected
to a serial port.
Parallel Interface Port: PRT
The parallel port on your system has a 25-pin, DB25 connector and is used to interface with
parallel printers and other devices using a parallel interface.

This connector allows you to connect a joystick or game pad for playing computer games.
This port can also be used to connect to MIDI devices.
