What Are Some Examples of Input and Output Devices?
An Input device is a hardware component that is used to enter data and instructions into a computer. There are three general types of Input devices: 1)Keyboards 2)Pointing devices(e.g:mouse,pointing stick,touch screen,graphic tablet, joy stick etc) 3)Source data entry devices(e.g:(1)scaning devices i.e;barcode reader,magnetic-ink character recognition reader(MICR), smart cards, imaging system, etc and (2)audio/video devicesi.e; audio input devices, video input devices and digital camera)

What are optical input devices?
Optical inout devices that uses light as a source of input. They eliminate the need for manual entry of data, thus accuracy increases. Three examples of optical input devices are: 1. barcode reader 2. image scanner 3. light pen Barcode readers convert a barcode (pattern of bars on products) to a code that computers can understand. Image scanners are of two types,flat bed and hand-held. Light pens use a light sensitive detector.

What is an example of an output?
A microphone and a computer mouse has only an output. A loudspeaker and a printer has only an input. That makes the mouse an INPUT device and the printer an OUTPUT device because they are named according to their use by the computer. It receives input from a mouse and sends output to a printer.
