DEFINITION OF INPUT/OUTPUT DEVICES

Alternatively referred to as an IO device, an input/output deviceis any hardware used by a human operator or other systems to communicate with a computer. As the name suggests, input/output devices are capable of sending data (output) to a computer and receiving data from a computer (input).


EXAMPLES OF INPUT/OUTPUT DEVICES

1. Digital Camera


A digital camera is a hardware device that takes pictures like a regular camera, but stores the image as data instead of printing it to film. Many digital cameras are capable of recording video in addition to taking photos. The picture is of a Casio QV-R62 with 6.0 Megapixelresolution, an example of a typical digital camera.


2. Touchscreen



A touchscreen is a display device that allows the user to interact with a computer by using their finger. They can be quite useful as an alternative to a mouse or keyboard for navigating a graphical user interface (GUI). Touchscreens are used on a variety of devices such as computer and laptop monitors, smartphones, tablets, cash registers, and information kiosks. Some touchscreens use a grid of infrared beams to sense the presence of a finger instead of utilizing touch-sensitive input.
