What is the difference between an input and output device?


Question

What is the difference between an input and output device?

Answer

To understand the difference between an input and output device, you must understand the difference between input and output. Any information or data that's entered or sent to the computer  to be processed is considered input and anything that is displayed from the computer is output. Therefore, an input device such as a computer keyboard is capable of having information sent to the computer, but does not display (output) any information. An output device such as a computer printer can print information from the computer but does not send any information (input) to the computer.

  1. Definitely believe that which you stated. Your favorite justification appeared to be on the internet
    the easiest thing to be aware of. I say to you, I certainly get
    irked while people consider worries that they just don't know about.
    You managed to hit the nail upon the top and also defined out the whole thing without
    having side effect , people can take a signal. Will likely
    be back to get more. Thanks
