14. UBUNTU -is a computer operating system based on Debian GNU/Linux. Its name comes from the Zulu word "ubuntu", translated as "humanity to others", describing the ubuntu philosophy: "I am what I am because of who we all are", a positive aspect of community. 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.

15. 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.

16. Ubuntu was initially forked from the Debian project's code base.cite_ref-history_7-0cite_ref-history_7-0[8] The aim was to release a new version of Ubuntu every six months, resulting in a more frequently updated system. Ubuntu's first release was on October 20, 2004. Ubuntu is currently funded by Canonical Ltd. On July 8, 2005, Mark Shuttleworth and Canonical Ltd announced the creation of the Ubuntu Foundation and provided an initial funding of US$10 million. The purpose of the foundation is to ensure the support and development for all future versions of Ubuntu.

23. PHILOSOPHY Our work is driven by a philosophy on software freedom that aims to spread and bring the benefits of software to all parts of the world. At the core of the Ubuntu Philosophy are these core philosophical ideals: 1. Every computer user should have the freedom to download, run, copy, distribute, study, share, change and improve their software for any purpose, without paying licensing fees. 2. Every computer user should be able to use their software in the language of their choice. 3. Every computer user should be given every opportunity to use software, even if they work under a disability.
