Unix is a certification for OS.Unix is an open source system as such anyone can use its component.Unix operating based on CUI and does not support pointing device.

 

Unix and Linux are similar operating systems, but not identical.

Unix is ​​a separate operating system created in 1969. It's not free software and it's not under GNU license.

Linux is the so-called UNIX-like operating system. Unlike Unix is distributed under the GNU license - therefore is used by the designation GNU/Linux.

 

The term originally described the Unix operating system developed by AT & T. Today, most Unix term usually used for any system based on similar principles. Linux is one of those systems. Some tabloid media but from ignorance tend to have a habit of taking Linux to generate articles and especially the "statistics extensions Windows, Unix and Linux."
