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 ('humanity towards others') or another translation would be: '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 distribution 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, and since version 12.10, by displaying optional advertisements in the Dash, a search component of Unity in desktop Ubuntu.
