Serial Connector
Use the 9-pin serial connector to attach a serial device to the computer. The serial connector passes data in serial format (1 bit at a time over one line). This
connector supports a variety of devices, including a serial mouse, that require serial data transmission. If you reconfigure your hardware, you may need pin
number and signal information for the serial connector.

Parallel Connector
Use the 25-hole parallel connector to attach a parallel device to the computer. The parallel connector is used primarily for printers. The parallel connector
transmits data in parallel format, where 8 data bits (one byte) are sent simultaneously over eight separate lines.
The parallel connector can also be configured for compatibility with the PS/2 standard. Support for the EPP feature improves network adapter performance
(adapters connect to the computer's parallel connector and require the appropriate software drivers from the adapter's manufacturer).
