<em>Roles</em> are used to group and classify users; each user can be assigned one or more roles. By default there are two roles: <em>anonymous user</em> (users that are not logged in) and <em>authenticated user</em> (users that are registered and logged in). Depending on choices you made when you installed Drupal, the installation process may have defined more roles, and you can create additional custom roles on the <a href="@roles">Roles page</a>. After creating roles, you can set permissions for each role on the <a href="@permissions_user">Permissions page</a>. Granting a permission allows users who have been assigned a particular role to perform an action on the site, such as viewing a particular type of content, editing or creating content, administering settings for a particular module, or using a particular function of the site (such as search).
