Internal link = link to a page on this wiki, using only the page name itself. Syntax: display name Example: This link leads to the Gondor page

External link = link to any page in the world wide web, using the full url. It is possible to use the external link syntax for links on this wiki. Syntax: display name Example1: This link leads to Google Example2: This is an external link that still leads to the Gondor page

As you can see, the google link has a symbol added to show that it's an external link. For normal wiki editing, you usually only need internal links.
