Concept:An output device is any computer hardware that communicates processed results to the user in a human-understandable form.
Explanation:The current answer wrongly says that output devices send results to the computer's memory.
That phrase actually describes an input action, because data or instructions entering the computer are stored in memory.
Input devices send data and instructions into the computer.
Output devices receive processed data from the CPU or memory and then display, print, or play it for the user.
Common examples are the monitor, printer, and speakers.
None of the four options correctly completes the sentence, since all of them mention sending items into the computer rather than sending results out to the user.
Answer:None of the options is correct. Output devices send processed results to the user.
