Start here

You speak into a tablet. Your words appear on the screen. What happened inside?

What this track covers

• The loop — something goes in, something happens, something comes out.
• The main parts — the screen, the keys and the parts inside.
• Input and output devices — the keyboard sends things in. The screen sends results out.
• Hardware and software — the parts you touch, and the instructions that run.
• Memory and storage — memory forgets when the power is off. Storage does not.
• Files and folders — one thing you saved, and where it is kept.

Touch a real device first. Then name its parts. Try each idea in its lab.
