(Personal System/2)PS/2 keyboard

(Personal System/2) PS/2 may be a type of port employed by older computers for connecting input devices like keyboards and mice. The port was introduced with (International Business Machines) IBM’s Personal System/2 computer in 1987 (which was abbreviated “(Personal System/2)PS/2″). In the following years, the (Personal System/2)PS/2 port became the standard connection for keyboards and mice in all (International Business Machines) IBM compatible computers.

The (Personal System/2)PS/2 port has six pins and is roughly circular in shape. Since each (Personal System/2)PS/2 port is designed to accept a specific input, the keyboard and mouse connections are typically color-coded. For example, the keyboard port on the back of the PC is often purple, while the mouse port is usually green color. Similarly, the connector on the end of the keyboard cord is most purple and the mouse cord connector is green color. This makes it easy for all users to know where to plug the cables into the PC. The conception is comparable to the color-coded composite audio/video output connections on the rear of a TV, that use red, white, and yellow color connectors.

While the (Personal System/2)PS/2 port enjoyed a good run for almost two decades, now most keyboards and mice use Universal Serial Bus (USB) connectors (connect for USB Port). Unlike (Personal System/2)PS/2 ports, Universal Serial Bus (USB) devices can be plugged into any Universal Serial Bus (USB) port or even a Universal Serial Bus (USB) hub and the computer will automatically determine what the device is. Universal Serial Bus (USB) is also “hot swappable,” meaning the connections can be removed while the computer is running. If you remove a (Personal System/2)PS/2 device while the computer is on, it may potentially cause damage to the hardware. Therefore, if you are using a (Personal System/2)PS/2 device, it is best to turn off the computer before connecting or unplugging a keyboard or mouse.
