Browser - Clear Cache

Browser - Clear Cache

What is the difference between using F5 and Ctrl+F5 to refresh a webpage? F5 reloads the page from server, but uses browser's cache for page elements like scripts, image, CSS stylesheets, etc, etc. But Ctrl+F5, reloads the page from server and also reloads its contents from server and doesn't use local cache at all.
