DefinitionOutput (出力) is the function that sends the results of processing inside the computer out in a form people or external devices can use.
ExplanationOutput is handled by output devices, for example a display that shows things on screen, a printer that puts them on paper, or a speaker that produces sound. What they send out is data held in storage, such as the results of computation.
