Inside the ComputerComputer Architecture

The Desk and the Warehouse

Computers keep a tiny super-fast memory for what you'll need next

Your phone reopens the app you just closed in a blink, but a new one makes you wait. Same phone. What changed?

You'll find out

  • How far away your data really is
  • Why the fastest memory is tiny
  • What “clear your cache” really does

Why it matters

Every app, game and website feels fast for the same reason: a small, quick copy kept close at hand.
