The Browser cache is a copy of web pages, pictures, videos, and other content viewed with your browser. It helps reduce the number of requests for sites: if the page you want to view is already in the cache, the browser will instantly load it from your hard drive.
Cache should be cleaned periodically to free up memory on your hard drive and in case web pages don't display correctly - for example, in an old design.
