The standard release of Drupal, known as Drupal core, contains basic features that can be used to
create a classic brochure website, a single- or multi-user blog, an Internet forum, or a community website
with user-generated content.
There are thousands of additional modules (known as contributed or “contrib”
modules) that extend Drupal core’s functionality, covering a broad spectrum of capabilities, including
e-commerce, social networking, integration with third-party applications, and multimedia.
