With the help of a mouse, we can move the cursor or any object on the computer screen from one place to another. A command, dialog box or icon can also be selected using the mouse. The mouse is connected to the PS-2 or USB port built on the computer motherboard. The mouse may have two or three buttons, which are called Right, Left and Center buttons.
