Ubuntu 11.10

Ubuntu ( /ʊˈbʊntuː/ oo-boon-too) is a computer


 operating system based on the Debian Linux distribution 


and distributed as free and open source software. It is


named after the Southern African philosophy of Ubuntu


 ("humanity towards others"). Ubuntu is designed primarily


 for use on personal computers, although a server edition 


also exists.

Ubuntu is sponsored by the UK-based company Canonical


 Ltd., owned by South African entrepreneur Mark


 Shuttleworth. Canonical generates revenue by selling


 technical support and services related to Ubuntu, while the


 operating system itself is entirely free of charge. The 


Ubuntu project is committed to the principles of free


 software development; people are encouraged to use free software, improve it, and pass it on.
