Cached data are files, scripts, images, and other multimedia stored on your device after opening an app or visiting a website for the first time. This data is then used to quickly gather information about the app or website every time revisited, reducing load time.
What data does cache store?

What should be stored in cache?
The data in a cache is generally stored in fast access hardware such as RAM (Random-access memory) and may also be used in correlation with a software component. A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer.

Does clearing cache delete photos?

Is cache stored in RAM?
Memory caching (often simply referred to as caching) is a technique in which computer applications temporarily store data in a computer’s main memory (i.e., random access memory, or RAM) to enable fast retrievals of that data. The RAM that is used for the temporary storage is known as the cache.
Where are cache files stored?
On Windows, the path to locate the browser cache is a little different. For example, for Google Chrome it looks like this: C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\Cache. You can also find Chrome’s cache folder using the Run command.
Is RAM the same as cache?

What data structure does cache use?
An LRU cache is built by combining two data structures: a doubly linked list and a hash map. This lets us access the LRU element in O ( 1 ) O(1) O(1) time by looking at the tail of the list.
Where is cache value stored?
The Browser Cache: a memory cache. A memory cache stores resources locally on the computer where the browser is running. While the browser is active, retrieved resources will be stored on the computer’s physical memory (RAM), and possibly also on hard drive.
