Follow one simple example: writing a document.

01 Input

Your keyboard sends keystrokes. Your mouse sends movement and clicks.

02 Processing & storage

The CPU runs the editor, RAM holds your current work, and storage keeps the file when you save.

03 Output

The GPU prepares the display. Your monitor shows the page, and a printer can put it on paper.

Remember: RAM ≠ storage.RAM loses its contents when power is off. Storage keeps your saved files.
