Drupal terminology

Site building basics

Modules
Modules are plugins and core functionalities for Drupal that provide functionality and
features while extending Drupal’s core functionality. Third party modules must be uploaded, enabled, configured, and then permissions set for users/access; core modules must be enabled, configured, and permissions set. One example of a module is the forum module.

Themes
Themes are overall site design and some basic layout which are driven by template files,
generally tpl.php files. Recently, themes have been created which support CSS (aka Zen Garden)
and more traditional coding.

Blocks
Blocks are the how the actual components of the website are displayed: categories, webpages, login information, etc. Blocks are generated by the modules; however, blocks can be greated manually, too. Blocks are NOT content; just the framework for the content.

Menus
Menus function in the same way as blocks, except there only goal is to provide an easy means of setting up navigational elements. Navigation can be broken down into mini-menus
which can be then weighted or hidden from users not able to use them.

Contact Form
Contact Form is a built in basic form generator for creating a contact form. It generates both the content and parameters for use.

URL aliases
URL aliases changes your site's URL paths by aliasing them.

Content management

Nodes
Nodes are the actual content container, similar to a website folder or individual webpage.

Categories
Categories create vocabularies for organizational purposes.

Comments
Comment management lists, edits and moderates comments (if applicable).

Content
Manage the actual content: view, edit, and delete site content.

Content type
Content type allows different kind of content to be assigned different functionalities. Content in a book page format will be hierarchical. Content in a page format is just a traditional webpage.

Posts settings
Control content behavior, such as teaser length, requiring previews before posting, and the number of entries (posts) on the front page.

RSS Settings
Configure the number of items per feed and whether feeds should be titles/teasers/full-text.
