What is cache?

[deanodrums]

I keep seeing on these forums about clearing cache. Juat a simple question. What is cache and why do you have to clear it? What are the benefits?
I ask as I have absolutely no idea what it is or does. Thanks.

In layman's terms, cache is a partition of the Android OS that stores temporary files. It has data that apps have quick access to improve performance. It generally shouldn't cause problems, but when there is, clearing the cache can potentially fix them.

This should give you a better idea of how and when to clear it: http://www.androidcentral.com/android-201-how-and-when-clear-app-cache-or-data
