PS/2
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.
Today, new computers use USB (universal serial bus) for the keyboard and mouse.
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.
PS/2 was featured as a top term of 1990.
Below, the picture shows a teal green PS/2 plug and an illustration of the PS/2 connection with its pin layouts.
Why is my PS/2 port half purple and half green?

What gender is the PS/2 port and plug?
The PS/2 port is a female and the PS/2 plug is a male gender.
