Linux is originally developed by Linus Torvalds at University of Helsinki in Finiland. It is a clone of UNIX operating system. It offers many features like UNIX. Linux runs on the machines with Intel 80386 processors or better. It also works on Intel compatable CPUs such as AMD & Cyrix

        Linux is a free, UNIX work-alike designed for Intel processors on PC architecture machines. Linux is not UNIX, as UNIX is a copyrighted piece of software that demands license fees when any part of its source code is used. Linux was written from scratch to avoid license fees entirely, although the operation of the Linux operating system is based entirely on UNIX. It shares UNIX's command set and look-and-feel, so if you know either UNIX or Linux, you know the other, too.

        Linux is copyrighted under the GNU/General Public License, sometimes called the GPL or copyleft. (Note the left instead of right.) This copyleft license was developed by the Free Software Foundation to enable programmers to write "free software," where "free" refers to freedom, not just cost.
