Ubuntu is a computer operating system based on the Debian Linux distribution and distributed as free and open source software, using its own desktop environment. It is named after the Southern African philosophy of ubuntu, which can be translated as "humanity towards others" or "the belief in a universal bond of sharing that connects all humanity".
As of 2012, according to online surveys, Ubuntu is the most popular Linux-based operating system on desktop/laptop personal computers, and most Ubuntu coverage focuses on its use in that market. However, it is also popular on servers and for cloud computing.
Development of Ubuntu is led by Canonical Ltd., a UK-based company owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and services related to Ubuntu. According to Canonical, the Ubuntu project is committed to the principles of open source development; people are encouraged to use free software, improve it, and distribute it.
