Ubuntu is a community developed operating system that is perfect for laptops, desktops and servers. Whether you use it at home, at school or at work Ubuntu contains all the applications you'll ever need, from word processing and email applications, to web server software and programming tools.

Ubuntu [uːˈbuːntuː] in English, [ùɓúntú] in Zulu is a free computer operating system based on the Linux kernel. Its name comes from the Zulu word ubuntu, loosely translated as "humanity" or "A person is a person only through other people".

Ubuntu is and always will be free of charge. You do not pay any licensing fees. You can download, use and share Ubuntu with your friends, family, school or business for absolutely nothing.

Ubuntu is designed with security in mind. You get free security updates for at least 18 months on the desktop and server. With the Long Term Support (LTS) version you get three years support on the desktop, and five years on the server. There is no extra fee for the LTS version, we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.

Everything you need comes on one CD, providing a complete working environment. Additional software is avalable online.

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, claiming approximately 30% of desktop Linux installations in a survey.

Ubuntu is free and open source, meaning that not only is it distributed without charge, but it may also be freely improved upon. Ubuntu is sponsored by Canonical Ltd, which is owned by South African entrepreneur Mark Shuttleworth. Instead of selling Ubuntu itself, Canonical makes money by selling paid support for Ubuntu. By keeping Ubuntu free and open Canonical is able to leverage the talents of outside developers willing to contribute rather than having to do all development within the company itself.

Kubuntu and Xubuntu are official subprojects of the Ubuntu project, aiming to bring the KDE and Xfce desktop environments, respectively, to the Ubuntu core (by default Ubuntu uses GNOME for its desktop environment). Edubuntu is an official subproject designed for school environments and should be equally suitable for children to use at home. Gobuntu is an official subproject that is aimed at adhering strictly to the Free Software Foundation's Four Freedoms. Ubuntu JeOS (pronounced "Juice") is the newest official subproject. JeOS is a concept for what an operating system should look like in the context of a virtual appliance.

Ubuntu releases new versions every six months, and supports those releases for 18 months with daily security fixes and patches to critical bugs. LTS (Long Term Support) releases, which occur every two years,[9] are supported for three years for desktops and five years for servers.
