What does it mean when you have to "clear your cache and update your browser" on your computer?

Clearing cache simply means deleting all the information that the browser's cache stores after you visit numerous webpages. Once you clear the cache, your computer speed increases thus giving you a good operating PC. This also helps the cache load with the current content.
