The big idea
When you talk to AI on your phone, the answer doesn't come from your phone. It comes from a giant warehouse far away, full of thousands of computers humming together.
Some examples
Data centers are usually in cool places to keep computers from overheating.
Some are bigger than 10 football fields put together.
Your message zooms through cables under the ocean to reach them.
All those computers use a LOT of electricity — like a small city.
Try it!
Look up 'data center' images online with a grown-up. Notice how many blinking lights and cables you see!
