PS/2 may refer to any of the following:
1. The PS/2 (Personal System/2) port, also referred to as 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 that contains six pins and is still sometimes found on all IBM compatible computers.
Today, new computers use USB for the keyboard and mouse.
The picture shows what the PS/2 ports may look like on the back of your computer. As can be seen by both of these 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.
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.
