What is a Computer Mouse?
The mouse is a computer device that controls the position of the mouse cursor on the screen. You operate the mouse placing your hand over it and dragging it across a surface, such as the computer desk or a mousepad. The moues is usually next to the computer keyboard, at its right because when it's operated with the right hand. Most PCs have a mouse and a keyboard. Mouses usually have two buttons, called left button and right button, and a "scroll wheel" at the middle that can be spun and when pressed works as a "middle button."
