PS/2 Cable (Personal System/2) port, also referred to as the mouse port or keyboard port, was develop by IBM.
It is use 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.
PS/2 was an IBM computer introduces in 1987.
It featured improved graphics, a 3.5-inch diskette drive, a proprietary bus to help prevent clone makers competition, and a bidirectional 8-bit port.
A Personal System/2 (PS/2) connector is a 6-pin connector used to connect peripheral devices, usually a mouse or keyboard, with a computer.
Its name comes from the IBM series of personal computers, known as the Personal System/2.
The PS/2 connector is the replacement of an older standard, DE 9 RS.232, used for mouse and keyboard connections.
Normally PS/2 connectors are available in two different sizes or shapes. One is 1/4 of an inch in diameter and other is 3/8 of an inch.
Both sizes are on the market, but the smaller one is more commonly used.
USB connectors have almost entirely replaced PS/2 connectors as the primary means of hooking up computer devices.

PS/2 originally had very few weak points regarding software and hardware.
Software problems began cropping up in 2010 because most drivers quit supporting PS/2 connectors.
This issue cannot be solved with the use of an adapter.
