What is Caching?
A cache is an area in the computer’s memory that stores recently used information. When a site is cached, it means the site’s pages, images, files and Web objects are stored on the user’s local hard drive. This in turn means that when a user opens a frequently accessed file, the browser will have most (if not all) of its files cached.
When a browser doesn’t have to retrieve new information every time a site is accessed it results in faster page load times. Caching plugins work the same way. The save dynamically generated HTML files in the cache and serve them next time a request is made instead of re-loading all of the PHP scripts from WordPress. Wordpress cache plugins create static html files from your dynamic WordPress blog. When a page is rendered, php and mysql are used. Therefore, system needs RAM and CPU. If many visitors come to a site, system uses lots of RAM and CPU so page is rendered so slowly. In this case, you need a cache system not to render page again and again. Cache system generates a static html file and saves it for future use.
