A computer mouse is the input device that controls the cursor on the monitor.

Different types of Mouse are available in the market.. The main types are Mechanical Mouse and Optical Mouse.

· Mechanical mouse consists of a hard rubber ball that rolls as the mouse is moved. Sensors inside the mouse body detect the movement and translate it into information that the computer interprets.

· Optical mouse uses an LED sensor to detect tabletop movement and then sends off that information to the computer.

The mouse is used for selecting part or full text or object, and also for dragging and dropping the selected text or object.

How to handle the mouse?

When we slide the mouse left across the mouse pad the mouse pointer on the screen moves left on the screen. When we slide it right the pointer moves right. When the mouse is moved forward or backward, it causes the pointer to move up and down.

The following actions are performed with the mouse :
