PORTS ON MOTHERBOARD

PS/2 PORT

Port has 6-pins.

It is a female port.

It require 6-pin male connector.

The mouse is connected with a PS-2 mini-DIN connector. Green is for mouse. The keyboard is connected with a PS-2

mini-DIN ( Deutsches institut Fur Normung) Connector.

Purple is for Keyboard.

PS/2 PORT

SERIAL PORT

Device is capable of Receiving one bit at a time.

It is a 9 pin male port.

SERIAL PORT CONNECTOR

Uses either a 9-pin or 25-pin connector and a cylindrical cable much less susceptible to interference. Can be up to 25 feet long.

It require 9 pin female connector.

Use to connect External modems and old mouse. Transfer of data at speeds of 28.8Kbps, 33.6Kbps, 56.6Kbps and 128Kbps and above, they can easily reach the serial port theoretical maximum.

SERIAL PORT

PARALLEL PORT

Device is capable of receiving eight bit at a time. It is a 25 pin female port. We require 25 pin male connector. Port running at about 150Kb/sec. Dot matrix printers are connected. Utilize a male DB-25 pin connector on the computer and a male 36-pin Centronics cable at the printer end. Most cables will be no more than ten feet, to reduce electronic interference along the cable.
