A mouse allows you to control the cursor and move around the screen very quickly. Making the same movements with the arrow keys on the keyboard would take much longer. As you move the mouse on your desk, the pointer on the screen moves in the same direction. The pointer usually looks like an I-bar, an arrow or a pointing hand, depending on what you are doing.

A mouse has one or more buttons to communicate with the computer. For example, if you want to place the insertion point or choose a menu option, you just click on the mouse button, and the option is chosen.
