UBUNTU -OPEN SOURCE OPERATING SYSTEM

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 serversand for cloud computing.^{[citation needed]}

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 advertisements in Unity Dash, the default file manager in desktop Ubuntu.According to Canonical, the Ubuntu project is committed to the principles of free software development; people are encouraged to use free software, improve it, and distribute it.
