A cache which is pronounced as Cash is a memory to store up something temporarily. The files you automatically ask for or view by looking at a Web page are stored on your hard disk in a cache subdirectory under the directory for your browser such as Internet Explorer or Netscape Navigator. When you return to a page you’ve lately looked at, the browser can acquire it from the cache rather than the original server.

It thus helps you in saving your time and also rescues you from the burden of some additional traffic. You can usually vary the size of your cache, depending on your particular browser. Caches are included in personal computers in the form of various operations such as cache memory and disk cache. Caching can also be put into practice for Internet content by handing it out to multiple servers that are periodically rejuvenated. International, national, organizational, regional and other macro caches to which highly famous information can be dispensed and periodically updated through which most of the users get information. Also, another function and advantage of a cache memory is that it saves a lot of time for the user as well as the server.
