What is Drupal?

Drupal is an open-source, modular content management system (CMS) that comes with many tools to help organize, structure, find and re-use content on web sites and other applications. Open source software is not copyrighted (although it is licensed,) so anyone can download the source code, study it, change it and improve it. Open Source Software is known to build power through the collaborative manner in which it is developed.

Drupal offers a very sophisticated programming interface for developers, however no programming skills are required for installing and administering basic web sites. It runs on any computing platform that supports both a web server capable of running PHP and one of several database engines to store content and settings.

Drupal is being used as a back-end system for about two percent of the world's web sites, including about 30-percent of US government web sites and countless other simple to comples sites globally. 

Drupal is distributed under the terms of the GNU General Public License, which in part means anyone is free to download it, share it with others, and contribute back to the project. Because of this open development model, the people who work together to support it have grown organically into a community. This community, who work together and communicate openly to ensure their software remains secure and cutting edge, is on the rise, along with the capabilities of the software, and now total some 800,000 people around the world.
