The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system is called Debian GNU/Linux, or simply Debian for short. Debian systems currently use the Linux kernel.
With this broad selection of packages, Debian once again stays true to its goal of being the universal operating system. It is suitable for many different use cases: from desktop systems to netbooks; from development servers to cluster systems; and for database, web, or storage servers. At the same time, additional quality assurance efforts like automatic installation and upgrade tests for all packages in Debian's archive ensure that Debian fulfills the high expectations that users have of a stable Debian release. It is rock solid and rigorously tested.
