Web Cache-

Part 1: Web Cache is a network entity that satisfies HTTP requests on the behalf of an origin Web server. The Web cache has its own disk storage and keeps copies of recently requested objects in this storage. It is important because an intermediate cache, which is closer to the client than the web server, can serve the content; it takes less time for the resource to reach the client. This makes the web site seem more responsive and also it reduce network traffic.

Part 2: Think of caching like maintaining your personal address book. All the phone numbers in there are available in the phonebook, but for speedier access, you maintain a list of the numbers that you call most frequently.
