What is a PS/2 connector?

A PS/2 connector is a 6-pin round connector primarily used for connecting keyboards and mice to computer systems. Developed by IBM, it was introduced in the mid-1980s as a replacement for older serial and parallel ports.

Yes, there are two variants: one for keyboards (usually purple) and one for mice (usually green). These variants ensure proper connection to the respective ports on the computer.

The PS/2 connector utilises a simple interface protocol that enables keyboards and mice to communicate with the computer. Unlike USB connections, PS/2 connections are not hot-swappable, meaning devices must be connected or disconnected while the computer is turned off to avoid potential damage.

The PS/2 connector typically features six pins, with the keyboard variant having a different pinout arrangement from the mouse variant. This distinction ensures keyboards and mice are connected to the correct ports on the computer.

PS/2 cables are generally relatively short, intended to connect peripherals directly to the computer. Standard cables are typically a few feet in length, providing enough flexibility for positioning the keyboard and mouse near the computer.

While PS/2 connectors have largely been replaced by USB connections in modern computer systems, they are still used in certain niche applications and with legacy hardware. Some users prefer PS/2 connections for keyboards and mice due to perceived advantages in latency and compatibility with certain keyboard features. However, the majority of modern computers no longer include PS/2 ports, and USB has become the standard for connecting peripherals.
