      • Monitor-A device that outputs a visual display of the user interface of any software that is currently being used on the computer.We use it so we can see the data we are working with and can interact with it. Without the monitor, we wouldn’t be able to see the effect of our inputs.
      • Projector - This is an alternative to a monitor for outputting a visual display from the computer. The difference is it projects the visual display onto a wall or screen.This is popular for watching television and film on, as well as in the classroom to display a presentation.
