This document provides an overview of key concepts in Drupal including nodes, content types, modules, menus, blocks, views, regions and themes, users, permissions and roles, and Drupal's database and flow. It defines nodes as pieces of content on a Drupal site like forum posts, blog entries and news articles. It describes content types as defining default settings for nodes. Modules extend Drupal functionality, menus provide site navigation, blocks display information in regions, and views control how lists and tables are presented. Themes control a site's design. Users have roles and permissions to control what they can do. Drupal stores information in database tables.

4. Node
A node in Drupal is the generic term for a piece of content on
your Drupal web site. A node consists of several fields. (Note
that the choice of the word "node" is not meant in the
mathematical sense as part of a network.)
Some examples of nodes:
• Discussion topics in forums
• Blog entries
• News article
• Any content.

5. In Drupal, each item of content is called a node, and each node
belongs to a single content type, which defines various default
settings for nodes of that type, such as whether the node is
published automatically and whether comments are permitted.
(Note that in previous versions of Drupal, content types were
known as node types.)

6. A module is a software (code) that extends Drupal features
and/or functionality. Core modules are those included with the
main download of Drupal, and you can turn on their
functionality without installing additional software. You can also
create your own modules using a rich set of Drupal APIs.

7. Menus are a collection of links (menu items) used to navigate a
website. There are three standard menus in Drupal:
•Primary Links
•Secondary Links
•Navigation

9. *The Views module provides a flexible method
for Drupal site designers to control how lists
and tables of content, users, taxonomy terms
and other data are presented.
*This tool is essentially a smart query builder
that, given enough information, can build the
proper query, execute it, and display the
results.

10. Blocks are discrete chunks of information that are displayed in
the regions of your site's pages. Blocks can take the form
of menus (which are concerned with site navigation), the output
from modules (e.g., hot forum topics), or dynamic and static
chunks of information that you've created yourself (e.g., a list of
upcoming events).

11. Regions:
Pages on your Drupal site are laid out in regions, which can
include the header, footer, sidebars, and main content section;
your theme may define additional regions.
Themes:
The theme controls how your site is displayed, including the
graphic look, layout, and colors. A theme consists of one or
more PHP files that define the HTML output of your site's
pages, along with one or more CSS files that define the
layout, fonts, colors, and other styles.

13. Every visitor to your site, whether they have an account and log
in or visit the site anonymously, is considered a user to Drupal.
Each user has a numeric user ID, and non-anonymous users also
have a user name and an email address.
•Anonymous User
•Authenticated User

14. Users on your site can be assigned permissions via roles. To do
this, you first need to create a role ( "Content editor“
,"Member“ ). Next, you will assign permissions to that role, to
tell Drupal what that role can and can't do on the site.
Finally, you will grant certain users on your site your new role.
Which will mean that when those users are logged in, Drupal will
let them do the actions you gave that role permission to do.
Default Roles
•Anonymous user
•Authenticated user
•Administrator

15. Drupal stores information in a database; each type of
information has its own database table. For instance, the basic
information about the nodes of your site are stored in the Node
table, the field information is stored in separate tables.
Comments and Users also have their own database tables, and
roles, permissions, and other settings are also stored in
database tables.
