Ubuntu (pronounced /ʊˈbʊntuː/)[5][6] is a computer operating system based on the Debian GNU/Linux distribution and distributed as free and open source software. It is named after the Southern African philosophy of Ubuntu (“humanity towards others”).[7]
With an estimated global usage of more than 12 million users,[8] Ubuntu is designed primarily for desktop use, although netbook and server editions exist as well.[9] Web statistics suggest that Ubuntu’s share of Linux desktop usage is about 50%,[10][11] and indicate upward trending usage as a web server.[12]
