Question

diffrence between absolute and relative address

Answer 1

The main difference between an absolute URL and a relative URL is that, an absolute URL is a complete address that points to a file or a resource, while a relative URL points to a file relative to the current directory or file. Absolute URL contains more information than a relative URL, but using relative URLs are much easier since they are shorter and more portable. But relative URLs can only be used to refer to links that reside on the same server as the page that refers them.
