Different Types of Mouse Connector

A mouse connector is a dedicated socket or an interface on the computer. The invention of the first personal computer by IBM back in 1981 and its predecessors developed different types of mouse connectors.

 

A, Bus mouse

This was the first type of mouse connected to the PC using a bus in th early days of IBM compatible PC through a specialized bus interface implemented via ISA add-in card.

C. PS/2 mouse

This superceded the serial connector, it is a 6-pin mini-DIN connector used for connecting mouse & keyboard to PC compatible. Back in the day, computers would normally come with at least two PS/2 ports—one for the keyboard, and one for the mouse. The keyboard port painted blue and the mouse port painted turquoise/green.

 

Most systems including PS/2 ports these days will come with a single PS/2 port where you can plug either a mouse or a keyboard, or use a splitter to connect both. This type of connector you need to reboot your computer to recognized your mouse and pins is fragile or worst could damage it.
