What is a node?

The term node is a catch all term for any content form in use in a Drupal site. So this means that a Page is a node, so is a Story, and a Book page - and any other content type that might exist in Drupal.

Why is the term node used?  There are actually a couple of really good reasons for this...

First, a node, in mathematical terms, is a point where several connecting lines come together - like a point on a map.  If you were to create a map of a web site, you would see that the web "pages" are usually connected, and often times they may be connected in many different ways.  Semantically speaking, the term node is actually a much more precise term than "page".

Second, in a Drupal site, one of the basic content types is called the Page content type.  Referring to all nodes as Pages to a Drupalista may cause some confusion - especially if working on a site where the Page content type isn't even used.
