 UNIX - encyclopedia article about UNIX.
operating system In computing, an operating system (OS) is the system software responsible for the direct control and management of hardware and basic system operations.
The Unix systems are characterized by various concepts: plain text files, command line interpreter A command line interpreter is a computer program which reads lines of text that the user types and interprets them in the context of a given operating system or programming language.
Only systems fully compliant with and certified to the Single UNIX Specification The Single UNIX Specification (SUS) is the collective name of a family of standards for computer operating systems to qualify for the name "Unix".

 Chapter 1. Introduction
Darwin is an advanced BSD UNIX operating system for PowerPC and x86 compatible architectures, currently owned and developed by Apple Computer, Inc. It forms the core of Apple's flagship Mac OS X operating system, which has been catapulted from its release in 2001 to being the most widely distributed UNIX-based operating system.
OpenDarwin is an operating system based on Apple's Darwin, but with certain "value added" features.
While it could be used on a web server, there are many other operating systems that are far more mature, better supported and so on.

The system's kernel is based on Mach 3.0 from Carnegie-Mellon University and FreeBSD 3.2 (derived from the University of California at Berkeley's BSD 4.4-Lite), the most highly regarded core technologies from two of the most widely acclaimed OS projects of the modern era.
Additionally, Mac OS X extends support to UFS, a flat disk system similar to the standard volume format of most UNIX operating systems, and the POSIX file system semantics, which makes it easier for developers to bring server applications to the new operating system.
This groundbreaking operating system delivers the performance and stability needed for 21st Century computing.

The GNU-Darwin Distribution is a free operating system and a popular source of free software for Mac OS X and Darwin-x86 users, but it is also a platform for digital activism.
Recently, Apple's public source license was revised so that Darwin could be distributed as an FSF recognized free operating system, and we have modified Darwin in accordance with that goal, so that the GNU-Darwin developers now feel free to compete directly against "Linux" and other "open source" projects.
We would hope that SCO users and employees would have a similar response to the actions of the free software community, which are for their benefit in the long run.
