Linux Torvalds started Linux based on Minix, a UNIX-type operating system. In opposition to make a non-distributable software, Linus released its code invention to others developers to make improvements to it. Moreover, Linux was borned “patent-absent” to make easier the code edition and the sharing capability.

UNIX, was developed by many companies, and there are many distribuitors, too. However, it can be distinguished two development branches:
