*   Mouse  

 

A mouse is a pointing device with a roller on its base. A mouse makes the process of navigating the screen much easier than trying to use just a keyboard. A mouse controls the movement of a pointer (also called mouse pointer) on the screen. When a mouse moves on a flat surface, the cursor on the screen also moves in the direction of the mouse's movement. A mouse usually uses a ball, light or a laser to track movement.   The mouse is a small device used to point to a particular place on the screen and select in order perform one or more actions. It can be used to select menu commands, resize windows, start programs, etc. The most conventional kind of mouse has two buttons on top where the left one is used more frequently than the right one. The mouse helps us to 'point at' and 'input' data by Single Clicking, Double Clicking and Dragging with the Left Mouse Button and Single Clicking with the Right Mouse Button. A mouse is a pointing device where the mouse's motion typically translates into the motion of a cursor on a display, which allows the control of a GUI (Graphical User Interface). The name mouse, originated at the Stanford Research Institute because of its resemblance to the common mouse with a tail.
