What is cached data?

Cached data is information which comes from a website or an app that is stored on your computer, smartphone and tablet.

This data is stored on your machine, so that the next time you go to use it, it’ll already be available.

Why does cached data do this?

The simple reason is to save on loading time. A website, for example, might save data about its layout on your PC. By doing this, it means your computer won’t have to load it from the internet all over again next time - it’ll already be there on the machine, which is much quicker.
