The content management system is a software that is used strictly for web site management. A CMS is like a newspaper e.g. In a newspaper writers write articles and then editor goes through those articles and then schedules them to be published and then articles appear on the news paper on their schedule. CMS work exactly in same fashion.

Many companies are allowing their software to be used for free because of the Free Software Movement. This movement was created in 1983, allowing software to be given for free. This movement was created in part because people were purchasing a copy of the software and then they would sell it but by making it free, so no one could profit because everyone knew the software to be free.

Drupal (pronounced Droo-puhl) is a highly successful open-source Content Management System (CMS). It is well‑respected for its robustness, its flexible and immaculate code, and its seemingly infinite capacity for extension and customization.

Drupal is a web-based Content Management System (CMS). Like many other CMS frameworks, Drupal provides a modular interface, so that developers can customize and extend the CMS system. However, one thing that distinguishes Drupal from other web CMS platforms is the power and flexibility of its modular system.

Drupal Themes
Themes are usually composed of a collection of templates, plus a handful of
supporting files like images, CSS files, and occasionally JavaScript files as well.

A template provides layout information for particular pieces of data—elements
like blocks or nodes. So when a typical Drupal page is rendered, several templates
are involved (one for the overall page layout, one for node content, one for block
content, and so on). Often, templates format data as HTML, though there is no
specific requirement that HTML be the target output language.

Most Drupal templates are written in the PHPTemplate "template language", which
is actually just a specially formatted PHP file with access to a limited number of
Drupal variables.
