I'm a complete Linux-based operating system, freely available with both community and professional support. It is developed by a large community and we invite you to participate too!The Ubuntu community is built on the ideas enshrined in the Ubuntu Philosophy: 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.These freedoms make Ubuntu fundamentally different from traditional proprietary software: not only are the tools you need available free of charge, you have the right to modify your software until it works the way you want it to.Ubuntu is suitable for both desktop and server use. The current Ubuntu release supports PC (Intel x86), 64-bit PC (AMD64), UltraSPARC T1 (Sun Fire T1000 and T2000) and PowerPC (Apple iBook and Powerbook, G4 and G5) architectures.
Ubuntu includes more than 16,000 pieces of software, but the core desktop installation fits on a single CD. Ubuntu covers every standard desktop application from word processing and spreadsheet applications to web server software and programming tools.
