Linux (commonly pronounced / lɪnəks/ LIN-əks in American English, also pronounced /ˈlɪnʊks/ LIN-ooks in Europe and Canada) refers to the family of Unix-like computer operating systems using the Linux kernel. Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers and video game consoles, to mainframes and supercomputers. Linux is the leading server OS, accounting for more than 50% of installations[citation needed]. Desktop use of Linux has increased in recent years, partly owing to the popular Ubuntu, Fedora, and openSUSE distributions and the emergence of netbooks and smartphones running an embedded Linux.
