Two types of links can be used when you create hyperlinks online: Absolute and Relative.
Absolute Links
Absolute Links contain the entire URL seen in the URL bar. For example:
http://www.mysite.com
http://www.mysite.com/page/Name
http://www.mysite.com/module/item
Relative Links
Relative Links contain only the portion after the domain name. Relative links are only operational if the destination of the link is the same domain as the link it’s on. For example:
/Admin
/page/Name
/module/item
