Trademarked UNIX, the Unix operating system was originally developed by a group of AT&T developers at Bell Labs. Unix was the first operating system written in the C programming language, and was designed to be portable (meaning it could run on or be made to run on many different types of hardware). Eventually through a combination of the portability, the C language, and the sharing of the system with academic and government institutions, a large number of different forms of Unix were created.

Today, in part because of this diversity, there is an Open Unix Standard which an operating system must be fully compliant with in order to be called Unix. Otherwise, systems are often called Unix-like.

The most-used Unix-like or Unix-based systems today are running operating systems like Linux, Mac OS X, and BSD
