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 customize and alter their software in whatever way they
Ubuntu will always be free of charge, and there is no
extra fee for the "enterprise edition”, we make our very best
work available to everyone on the same Free terms.
Ubuntu includes the very best in translations and accessibility
infrastructure that the Free Software community has to offer, to
make Ubuntu usable by as many people as possible.
Ubuntu is shipped in stable and regular release cycles; a new
release will be shipped every six months. You can use the current
stable release or the current development release. A release will be
supported for 18 months.
Ubuntu is entirely committed to the principles of open source software
development; we encourage people to use open source software, improve it and
pass it on.
Ubuntu is suitable for both desktop and server use. The current Ubuntu
release supports Intel x86 (IBM-compatible PC), AMD64 (Hammer) and PowerPC
(Apple iBook and Powerbook, G4 and G5) architectures.
Ubuntu includes more than 1000 pieces of software, starting with the Linux
kernel version 2.6 and GNOME 2.30, and covering every standard desktop
application from word processing and spreadsheet applications to internet
access applications, web server software, email software, programming
languages and tools and of course several games.
