PS/2 may refer to any of the following:

  1. The PS/2 (Personal System/2) port, also called the mouse port or keyboard port, was developed by IBM. It is used to connect a computer mouse or keyboard to an IBM compatible computer. The PS/2 port is a mini DIN plug containing six pins and is still sometimes found on all IBM compatible computers.

The picture shows what the PS/2 ports may look like on the back of your computer. As seen in the pictures, many computers have adopted the color codes purple and teal as identifications for each of the port. The mouse is teal and the keyboard is purple.

Today, new computers use USB for the keyboard and mouse.

Below, the left picture is an example of the PS/2 plug and the right illustration is of the actual PS/2 connection with its pin layouts.

For newer motherboards that still have a PS/2 port, for backward compatibility there may be one PS/2 port that is half purple and half green (teal). This port can accept either a PS/2 keyboard or PS/2 mouse.
