Cache is a "semi-temporary" data.

When you first visiting a website, your computer will downloaded the website data (image,script,etc), those are called cache.

When you visiting the same website, it will loaded faster because the file (image,script,etc) is already downloaded before.

But having too much cache will take up your storage and sometimes they're conflicting each other. That's why you need to clear your cache once in a while.
