A scanner is used to take information stored on paper and read it into a computer system. Scanners can be used to convert photographs, paintings and typed text into a form that can be stored in a computer. A flatbed scanner, like the one shown here, reads documents placed face down on it like a photocopier.
A graphics tablet is a flat pad with electronic sensors below the surface. These sensors detect the movements of the pointing device (stylus) and move the pointer on the screen. This device is used as input to computer-aided design (CAD) systems.
