  • It is an input device that is most often used with a personal computer.
  • Moving a mouse along a flat surface can move the on-screen cursor to different items on the screen.
  • Items can be moved or selected by pressing the mouse buttons (called clicking).
  • A mouse can also be used to drag-and-drop objects and give you access to the right-click menu1.
