You press a key. Something happens. A result appears. Later, you find it again. Four things just occurred — and together they describe everything a computer does.

Input is what enters the system: a keystroke, a voice, a click. Raw material, nothing more.

Input = enter — the starting point.

The CPU takes that raw material and works on it — calculating, comparing, deciding. You don’t see this step, but nothing useful happens without it.

Process = think — input becomes something meaningful.

The result surfaces: text on a screen, sound from a speaker, a printed page. The system has produced something you can use.

Output = show — the answer delivered.

But what about next time? Storage holds what came in and what came out — temporarily in memory, permanently on disk or cloud — so nothing is lost when the machine is off.

Storage = remember — the system doesn’t forget.

The Flow

Input → Process → Output → Storage

Every interaction with a computer, from a search query to a video render, is just this cycle — repeated, nested, and scaled.
