Ubuntu (play /ʊˈbʊntuː/ oo-boon-too)[7][8] 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").[9] 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.[10]
