The cache, in computing, is a place where data is stored temporarily. As a user, you often use the cache when using a web browsers. When you open a website, its contents are saved on your computer. As a website visitor, you don't notice this process, because the saving is done in the background. In the web, this enables faster rendering and shorter loading times. The data which is stored in the cache are HTML files, stylesheets, scripts, images and other media files. If you navigate on a website back and forward, the browser doesn't have to download all the data again but gets the required files from the cache. The browser compares superficialy what has been changed since the last visit so that only new files are downloaded.
