What Is Caching In Web Development?

Caching is a method of storing a copy of a resource and serving it back when it is requested. When a web cache has a requested resource in its store, it intercepts the request and instead of redownloading the resource from the originating server, it returns a duplicate of the cached resource.

Similarly, What is caching explain?
