Cache – pronounced as cash (like the money) – is used to temporarily store commonly accessed data for future use. Graphic images (such as buttons, banners, icons, advertising, graphs, and color bars), photographs, scripts and other parts of websites while you are browsing are examples of cache items. When going to a page on a website, your computer will first check its cache folder to see if it has already has those images and, if so, it won’t take the time to download them again. This makes for a faster loading of the page. Cache folders can get quite large, however, and can occupy 100 megabytes or more of hard drive space, storing graphics for sites you may never visit again, so it may be wise for those with storage concerns to empty the cache periodically. That will also enable the browser to access updated web pages without the older cache item interfering.
