Super-fast, easy to use and free, the Ubuntu operating system powers millions of desktops, netbooks and servers around the world. Ubuntu does everything you need it to. It'll work with your existing PC files, printers, cameras and MP3 players. And it comes with thousands of free apps.


Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit. "Ubuntu" is an ancient African word, meaning "humanity to others". The Ubuntu distribution brings the spirit of Ubuntu to the software world.
