How Does an Output Device Work?

In order to show the output, an output device uses a signal it receives from the computer to accomplish a task. An output device’s fundamental operation is listed below as an illustration.

• If you enter ‘Hi Geeks’ on a computer keyboard (input device), the computer receives the signal.
• Once the input has been processed by the computer, an output device—a monitor—is signalled.
• The display (output) of the ‘Hi Geeks’ on the screen occurs once the monitor receives the signal.
• Another example of an output device is a printer, which might print that ‘Hi Geeks’ if it were supported.

If the computer was working and had no output device attached, you could still type ‘Hi Geeks’ on the keyboard and it would still be processed. Without an output device, you couldn’t see what happened or verify the input, though.

Output Devices are those devices which show us the result after giving the input data to a computer system. Output can be in different forms like image, graphic audio, video, etc.
