The cloud is not a fluffy sky cloud. It means computers in other places, far away, that store and run things for you over the internet.

Think of it as a super-helpful computer, or lots of them, that you use over the internet.

Here is how it works. You ask for something, like a photo, video, or game. Your device sends the request over the internet. The cloud computer sends it back.

The cloud makes life easier, faster, and safer: you can reach your stuff from any device anywhere, it is stored and backed up safely, and you do not need to fill up your own device.

Real examples: photos backed up online so you do not lose them, videos you stream without downloading huge files, and games and school projects saved on faraway computers.

Remember: the cloud is computers far away, you connect over the internet, it stores and runs your stuff, and it is not a sky cloud!

What to remember

  • The cloud is computers in other places, reached over the internet.
  • It stores and runs things for you.

For grown-ups

'The cloud' is on-demand computing and storage running on someone else's servers, accessed over the internet. It trades local hardware for managed, scalable, backed-up infrastructure, which is why photos, streaming, and apps 'just work' across devices. The trade-off is trusting a provider with your data.
