Ubuntu is a Linux distribution offering an operating system predominantly targeted at personal computers. Based on Debian GNU/Linux, Ubuntu concentrates on usability, freedom from restriction of use, regular releases, and ease of installation.

Feature
Ubuntu’s focus on usability includes the widespread use of the sudo tool, which allows users to carry out administrative tasks without initiating an unsafe superuser session. Ubuntu furthermore emphasises accessibility and internationalisation, to reach as many people as possible.

Included Softwares
Ubuntu includes more than 16,000 pieces of software, but the core desktop installation fits on a single CD. Ubuntu is based on the GNOME desktop system, which is specifically designed to provide a free, simple and intuitive interface while offering a full range of modern desktop applications. Ubuntu comes with additional productivity software including OpenOffice.org, the Mozilla Firefox web browser and the GIMP raster graphics editor.

Vast Support
Release 6.06 is labelled Long Term Support (LTS) to indicate that Canonical (the sponsors) intend to support it with updates for longer than most Ubuntu releases. Package updates are planned for three years on the desktop and five years on the server, with paid technical support available from Canonical over the same period.
