node

Node is a single piece of content that is published on a Drupal site. All content on a Drupal website is stored and treated as "nodes". A node is any piece of individual content, such as a page, poll, article, forum topic, or a blog entry. Comments are not stored as nodes but are always connected to one. Treating all content as nodes allows the flexibility to create new types of content. It also allows you to painlessly apply new features or changes to all content of one type.

Node in Drupal 7 can be thought of as a section of content you would like to display on your website. Each node has the following attributes:

1. Content Type;

2. Node ID;

3. Title;

4. Creation date;

5. Author;

6. Body

   ;

7. Other additional properties.

You can create custom attributes and define your own content types. When you install modules, many of them will include additional fields (i.e. postal addresses, images, files, URLs, geographic geofields) and content types for you to use on your site, administered in the "Content Types" area under Structure in Drupal 7.

The ability to create different "content types" is a way Drupal allows you to have different kinds of nodes for different purposes. For example, an "article" is one content type, a "book page" is another, and a "blog entry" yet another. You can also create new content types of your own.
