How do I flush the browser's cache memory and what will I lose?
The browser's cache (pronounced "cash") is a space in your computer's hard drive and in RAM memory where your browser saves copies of previously visited Web pages. Your browser uses the cache like a short-term memory. Instead of downloading an image from a recently viewed website, it will load the image from your cache folder, thereby making the browsing process a little quicker.You can clear your cache (that is, delete all the files in your cache / computer memory) when they begin to occupy too much hard drive space, or when the files in the memory / cache get out of date and no longer correspond to the files on the Web server. (If you are not viewing a current version of the web page)Just find what browser you are using on the list.
