Cache (computing)

A computer's cache is like a mini storage word specially designed to store information it might need to use a lot. When the computer needs to access a file or website, it looks in its cache (which is a lot faster than searching on the internet) to see if it can find it. If it can find the information in the cache, it can access the file or website more quickly than it could if it had to look online. The cache stores the information so it doesn't have to look it up again until it's changed or updated.
