Five descriptions of different input or output devices are given in the table. Complete the table by stating the name of each input or output device.

1. (a)This is an input device that works by shining a light onto the surface of a document. The light source is automatically moved across the document and the reflected light is captured by mirrors and lenses.[1]
2. (b)This is an input device where a laser or a light source is moved across an object. The width, height and depth of the object are measured to allow a model to be created.[1]
3. (c)This is a large input device that is usually fixed to a wall. A user can calibrate the device to make sure the sensors align with a projected image. The user can use either their finger or a special pen to make selections.[1]
4. (d)This is an output device that uses many small mirrors to reflect light towards a lens. This will display an image.[1]
5. (e)This is an output device that creates an object by building layer upon layer of material.[1]
