What is Cache?

Cache (pronounced cash) is the act of storing objects in Web browsers' memory so repeat downloading is unnecessary. This can dramatically speed up website browsing speed, however, since files are stored locally on your computer, you may not always be seeing the latest version of a page as your browser will only check at certain intervals if the page being requested has been changed. To ensure that you are viewing the very latest version of a web page, you can manually clear your web browser's cache, or use a program to clear the data for you.
