A computer with an attached mouse allows you to move a cursor (often an arrow) around on the screen. By clicking the primary button of the mouse (Usually the leftmost button) you may select icons or open them. The mouse also aids in selecting multiple items and in completing other tasks that are difficult to do with only a keyboard.
