Link: absolute, relative, root
Internet Marketing Glossary - Definition:
Link: absolute, relative, root
The three ways to define a hyperlink’s destination. An absolute link is when the href value is a fully qualified URL like http://www.yourwebsite.com/homepage.html. This can only be used when linking between websites where the source and destination anchor have different domain names.
In the case of a relative link, the server already knows where the current document is. So, if you want to link to another document in the same directory, there’s no need to write out the full URL.
A root-relative link can only be used when linking within a website; when the destination anchor is under the same domain name.
