PS-2

=PS/2= PS-2 is a type of connector used to connect mice and keyboards to the computer. It got its name from Personal System/2 by IBM in 1987. The PS/2 connector design on keyboards and mice are similar, and uses the same set of plugs, but since the devices use different codes, they have to make one plug for each device. In order to note the difference between the connector for mice and keyboards, the producers colored the ones for keyboards purple, and green for mice. The PS/2 connectors were very popular until the invention of USB.
