Linux (commonly pronounced /ˈlɪnəks/ LIN-əks in American English,[3][4] also pronounced /ˈlɪnʊks/ LIN-ooks[5] 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 predominantly known for its use in servers; in 2009 it held a server market share ranging between 20–40%. Most desktop computers run either Microsoft Windows or Mac OS X, with Linux having anywhere from a low of an estimated 1–2% of the desktop market to a high of an estimated 4.8%.[10]
However, desktop use of Linux has become increasingly popular in recent years, partly owing to the popular Ubuntu, Fedora, Mint, and openSUSE distributions[11] and the emergence of netbooks and smartphones running an embedded Linux.[12][13]
The development of Linux is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed, both commercially and non-commercially, by anyone under licenses such as the GNU General Public License Citeste mai departe
