The term PS/2 in computing refers to a 6-pin Mini-DIN connector and a related interface protocol used for connecting keyboards and mice to a computer. The name originates from IBM's Personal System/2 series of personal computers, introduced in 1987, where it was first implemented.

Key aspects of the PS/2 computer term include:

PS/2 ports: These are the physical round sockets on a computer's motherboard. They are color-coded according to the PC 97 standard: purple for the keyboard and green for the mouse.

PS/2 interface: This is the protocol that enables communication between the input device and the computer. It uses a synchronous serial connection with dedicated clock and data lines for each device.

Legacy status: Though once the industry standard, PS/2 ports were phased out in the mid-2000s and replaced by the more versatile USB standard. Today, PS/2 is considered a legacy port, and most modern motherboards no longer include it.
