Ubuntu is a Debian-based Linux operating system, with Unity as its default desktop environment (GNOME was the previous desktop environment). It is based on free software and named after the Southern African philosophy of ubuntu (literally, "human-ness"), which often is translated as "humanity towards others" or "the belief in a universal bond of sharing that connects all humanity".

Development of Ubuntu is led by Canonical Ltd., a company owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue through the sale of technical support and other services related to Ubuntu. The Ubuntu project is publicly committed to the principles of open source development; people are encouraged to use free software, study how it works, improve upon it, and distribute it.

Ubuntu is a monster of an OS,it is the closest to competing with windows OS series.Ubuntu is constantly updated and is completely free, it comes under GPL(General Pulic Licence).It is an inspiration for development of OSs like Backtrack Kubutu, Lubuntu and 100s of more.

Ubuntu is easy to use and its appstore  is huge.There are more than 80,000 coders around the world contributing to ubuntu.
