Linux (Listeni/ˈlɪnəks/ lin-uks[5][6] or, less frequently used, /ˈlnəks/ lyn-uks)[6][7] is a Unix-like and mostly POSIX-compliant[8] computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel,[9] an operating system kernel first released on 5 October 1991 by Linus Torvalds.[10][11]
Linux was originally developed as a free operating system for Intel x86-based personal computers. It has since beenported to more computer hardware platforms than any other operating system.[citation needed] It is a leading operating system on servers and other big iron systems such as mainframe computers and supercomputers.[12][13][14] As of June 2013, more than 95% of the world's 500 fastest supercomputers run some variant of Linux,[15] including all the 44 fastest.[16] Linux also runs on embedded systems, which are devices whose operating system is typically built into thefirmware and is highly tailored to the system; this includes mobile phones,[17] tablet computers, network routers, facility automation controls, televisions[18][19] and video game consolesAndroid, which is a widely used operating system for mobile devices, is built on top of the Linux kernel.
The development of Linux is one of the most prominent examples of free and open-source software collaboration. The underlying source code may be used, modified, and distributed—commercially or non-commercially—by anyone under licenses such as the GNU General Public License. Typic
