Difference between Linux and Unix

Posted on Updated on

Linux is an operating system kernel, and UNIX is a certification for operating systems. The UNIX standard evolved from the original Unix system developed at Bell Labs. After Unix System V, it ceased to be developed as a single operating system, and was instead developed by various competing companies, such as Solaris (from Sun Microsystems), AIX (from IBM), HP-UX (from Hewlett-Packard), and IRIX (from Silicon Graphics). UNIX is a specification for baseline interoperability between these systems, even though there are many major architectural differences between them. Linux has never been certified as being a version of UNIX, so it is described as being “Unix-like.” A comprehensive list of differences between Linux and “UNIX” isn’t possible, because there are several completely different “UNIX” systems.

The above pictures show two type of operating system. one is Linux and another one is OpenBSD which is based on Unix.
