A breif introduction to linux operating system

Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. Linux kernel is the defining component of any Linux system. Its distributions may vary in many details of system operation, configuration, and software package selections. Linux can be used on a wide variety of computer hardware which includes mobile phones, tablet computers, network routers, televisions, video game consoles, desktop computers, mainframes and supercomputers. 90% of today's supercomputers run some variant of Linux. The packaged format of linux is known as a Linux distribution for desktop and server use. Some popular mainstream Linux distributions are Debian, Fedora and openSUSE. It also include the Linux kernel, supporting utilities and libraries and usually a large amount of application software to fulfill the distribution's intended use. A distribution oriented toward desktop use may include the X Window System and an accompanying desktop environment. Other distributions may include a less resource intensive desktop. A distribution made to run as a server may omit any graphical environment. It is possible for anyone to create a distribution for any intended use, because linux is freely redistributable. Commonly used applications with desktop Linux systems include the Mozilla Firefox web browser, the OpenOffice.org or Libre Office application suites, and the GIMP image editor.
