Debian GNU/Linux

Released in 1993 by the Debian Project, Debian is a Linux distribution that evolved from the Unix OS. It may be used as a desktop, server or embedded OS and supports a number of processor frameworks, including Intel, AMD and ARM.

Default Debian installation packages are bundled with utility/development tools, communications/email software, networking services and other applications designed for desktops and servers.

As of February 2011, the most current version is Debian 6.0, also known as Squeeze.
