Description

Ubuntu is a computer operating system based on Debian GNU/Linux. Ubuntu's goals include providing an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation. Ubuntu has been rated as the most popular Linux distribution for the desktop, claiming approximately 30% of desktop Linux installations in 2007.

Ubuntu is composed of free and open source software distributed under various licenses, especially the GNU General Public License (GPL) so that users are free to run, copy, distribute, study, change and improve the software. Ubuntu is sponsored by the UK based company Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth. Instead of selling Ubuntu for profit, Canonical creates revenue by selling technical support. By keeping Ubuntu free and open source, Canonical is able to take advantage of the talents of outside developers in Ubuntu's constituent components without developing the entire operating system itself.

Canonical releases new versions of Ubuntu every six months and supports Ubuntu for eighteen months by submitting security fixes, patches to critical bugs and including minor updates to programs. LTS (Long Term Support) releases, which occur every two years, are supported for three years on the desktop and five years for servers.
