A computer mouse is a handheld hardware input device that controls a cursor in a GUI and can move and select text, icons, files, and folders. For desktop computers, the mouse is placed on a flat surface such as a mouse pad or a desk and is placed in front of your computer. The picture to the right is an example of a desktop laptop mouse with two buttons and a wheel.
By using a laptop mouse, the user doesn’t have to memorize commands, such as those utilized in a text-based command line environment like MS-DOS. Whereas a Windows user only has to double-click to open a folder and see its contents.
