What is Unix?

Unix is an operating system developed in the early 1970s at AT&T Bell Labs. The following description was obtained from WhatIs.com.

The Unix system is an operating system that originated at Bell Labs in 1969 as an interactive time-sharing system. Ken Thompson and Dennis Ritchie are considered the inventors of the Unix system. The name (pronounced "yew-nix") was a pun based on an earlier system, Multics. In 1974, the Unix system became the the first operating system written in the C language. The Unix system has evolved as a kind of large free-ware product, with many extensions and new ideas provided in a variety of versions of Unix systems by different companies, universities, and individuals. Partly because it was not a proprietary operating system owned by any one of the leading computer companies and partly because it is written in a standard language and embraced many popular ideas, Unix became the first open or standard operating system. The Unix trademark is owned by the industry standards group, X/Open Company, which certifies and brands Unix implementations.

"UNIX is a registered trademark of The Open Group
 in the United States and other countries."

Unix is more than an operating system; it is a philosophy of programming and system design.
