The term ''Linux'' properly refers to just the operating system kernel itself., but generally using ‘''Linux kernel''’ to express the meaning. However, inIn popular parlance ‘Linux’ is used to refer to a complete [[Linux Distribution]] which includes [[GUI]] components and many other utilities, many of which are supplied by the [[GNU Project]]. [[Android (operating system)|Android]], for example also uses the Linux kernel but includes different components from most desktop Linux distributions.

The Linux kernel was originally developed as a free kernel for [[Intel x86]]-based personal computers. It has since been [[porting|ported]] to more computer hardware platforms than any other kernel. Linux based operating systems are the leading operating system type on [[server (computing)|server]]s and other [[big iron]] systems such as [[mainframe computer]]s and [[supercomputer]]s:<ref name="LinuxDevices">{{cite web | url = http://www.trl.ibm.com/projects/ngm/wp10_e.htm | title = Linux Watch | accessdate =29 September 2009 | last = [[IBM]] | year = 2001 | month = October}}</ref><ref name="IBMLinuxWatch">{{cite web | url = http://www.linuxfordevices.com/c/a/News/Trolltech-rolls-complete-Linux-smartphone-stack/ | title = Trolltech rolls "complete" Linux smartphone stack | accessdate =29 September 2009 | last = Linux Devices | year = 2010 | month = January}}</ref><ref>{{cite web | title = IBM's newest mainframe is all Linux | url = http://www.computerworld.com/s/article/9142007/IBM_s_newest_mainframe_is_all_Linux_ | last = Computerworld | first = Patrick Thibodeau | accessdate =22 February 2009 }}</ref><ref name="rules_supercomputers">{{ cite news | title = Linux rules supercomputers | url = http://www.forbes.com/home/enterprisetech/2005/03/15/cz_dl_0315linux.html | last = Lyons | first = Daniel | accessdate =22 February 2007 | work = Forbes | date = 15 March 2005}}</ref> more than 90% of today's [[TOP500|500 fastest supercomputers]] run some variant of Linux,<ref name="Top500 OS list">{{cite web | url = http://www.top500.org/overtime/list/32/os | title = Top500 OS chart | publisher = Top500.org | accessdate =31 October 2010}}</ref> including the 10 fastest.<ref>{{cite web | author = Henry Burkhardt, KSR | url = http://www.top500.org/lists/2011/06 | title = June 2011 &#124; TOP500 Supercomputing Sites | publisher = Top500.org | accessdate =15 September 2011}}</ref> Linux also runs on [[embedded system]]s (devices where the operating system is typically built into the [[firmware]] and highly tailored to the system) such as mobile phones, [[tablet computer]]s, network [[router (computing)|router]]s, televisions<ref>{{cite web | title = Sony Open Source Code Distribution Service | url = http://products.sel.sony.com/opensource/ | publisher = Sony Electronics | accessdate =8 October 2011}}</ref><ref>{{cite web | title = Sharp Liquid Crystal Television Instruction Manual | url = http://files.sharpusa.com/Downloads/ForHome/HomeEntertainment/LCDTVs/Manuals/Archive/tel_man_LC32_37_42HT3U.pdf | publisher = Sharp Electronics | accessdate =8 October 2011 | page=24}}</ref> and [[video game console]]s; the [[Android (operating system)|Android]] system in wide use on mobile devices is built on the Linux kernel.
