ABSTRACT
Linux is a free open source operating system based on UNIX. It was developed by Linus Corvalds. UNIX system was developed by bell laboratories. Bell laboratories never released the source code of UNIX. To make it affordable by common people Linus Corvalds developed Linux as an open source operating system. After its inception Linux became known to common people. Linux is the only system which covers a wide range of hardware applications. It covers small gadgets like cell phones to big servers maintained by U.S post office. Linux is multi-user and multi tasking.

Thirty year ago the computers were very big and slow. Each computer was software specific. Software works on one machine but will not run on another machine.

They developed a new operating system called UNIX in 1971. UNIX was simple and...
