There are two types of links in Org Mode: internal and external links. Internal links target headlines in a particular document while external links can not only link between Org documents and files, but also target resources on the web. This can as simple as an HTTP link, but there are different link types as well. Org documents can references Emacs Lisp scripts, Shell commands, Usenet groups and many, many more.
