An absolute link includes the full address in the 'href' value. A foolproof way to recognize if a link is absolute or not is to determine if the domain name exists within the address. For example, if you are on a website with an address of http://www.website-example.com, links to images and other web pages found within the website could be referenced by omitting the domain name and pointing to files in a relative manner such as href="images/logo.jpg". An absolute link to the same image would be listed as
http://www.website-example.com/images/logo.jpg.
