What Is Cached Data?

The cache is a term used to describe temporary storage. Thus, cached data is the collection of items saved within the cache storage location. Whenever a browser is requested for a specific file, it first checks if the resource is available locally. If not found, the browser sends a request to the corresponding web server and saves it as cached data depending on the file type.

How Clearing Cache Works?

Clearing browser cache removes all the data kept within the temporary storage. As a result, once you first access a website after clearing all the cache, it will take additional time to load. This occurs because no resources can be retrieved locally and all of them will have to be delivered by the corresponding web server.
