	Unix - Wikipedia, the free encyclopedia
		Unix or UNIX is a computer operating system originally developed in the 1960s and 1970s by a group of ATandT Bell Labs employees including Ken Thompson, Dennis Ritchie, and Douglas McIlroy.
		The Unix systems are characterized by various concepts: plain text files, command line interpreter, hierarchical file system, treating devices and certain types of inter-process communication as files, etc. In software engineering, Unix is mainly noted for its use of the C programming language and for the Unix philosophy.
		During the late 1970s and early 1980s, Unix's influence in academic circles led to massive adoption (particularly of the BSD variant, originating from the University of California at Berkeley) of Unix by commercial startups, the most notable of which is Sun Microsystems.

		Summarizing how pipes found their way into Unix, Vyssotsky notes that Thompson put them in, but "it was McIlroy who said, `look you ought to do it.' Pipes, like most things in Unix were not a radically new idea."(38) He describes how similar ideas had appeared in other languages like SIMULA as early as 1967.
		In addition, the developers were all trained in using this system and all the software tools had been developed."(99) The elaborate process of applying Unix to the IBM 3033AP is described by the researchers: "Over 300 tools, written in both C and shell command language, were identified and examined.
		The contributions to the evolution of Unix by researchers at Bell Labs and then by those at the University of California at Berkeley, and other users and programmers around the world who continued the development of Unix, are an important achievement in the development of the process of software creation.

	What is UNIX? - A Word Definition From the Webopedia Computer Dictionary
		Created by just a handful of programmers, UNIX was designed to be a small, flexible system used exclusively by programmers.
		UNIX was one of the first operating systems to be written in a high-level programming language, namely C.
		An operating system that is certified by The Open Group to use the UNIX trademark conforms to the Single UNIX Specification.

	What is UNIX ?
		The Open Group holds the definition of what a UNIX system is and its associated trademark in trust for the industry.
		Today, the definition of UNIX ® takes the form of the worldwide Single UNIX Specification integrating X/Open Company's XPG4, IEEE's POSIX Standards and ISO C. Through continual evolution, the Single UNIX Specification is the defacto and dejure standard definition for the UNIX system application programming interfaces.
		The Open Group is committed to working with the community to further the development of standards conformant systems by evolving and maintaining the Single UNIX Specification and participation in other related standards efforts.

	A Brief History of Unix
		UNIX was originally developed at Bell Laboratories as a private research project by a small group of people starting in 1969.
		UNIX had a relatively small amount of code written in assembly language (this is called the kernel) and the remaining code for the operating system was written in a high level language called C. The group worked primarily in the high level language in developing the operating system.
		In UNIX because the C language was written to be used to implement an operating system rather than a traditional "input-processing-output" application, use of these sophisticated features is quite easily done from the C language without writing any assembly language.

	The Creation of the UNIX* Operating System (Site not responding. Last check: 2007-11-07)
		UNIX* computer operating system from Bell Labs is still regarded as one of the most powerful, versatile, and flexible operating systems (OS) in the computer world.
		Its popularity is due to many factors, including its ability to run a wide variety of machines, from micros to supercomputers, and its portability -- all of which led to its adoption by many manufacturers.
		Like another legendary creature whose name also ends in 'x,' UNIX rose from the ashes of a multi-organizational effort in the early 1960s to develop a dependable timesharing operating system.
