Unix (officially trademarked as UNIX, sometimes also written as Unix with small caps In typography, small capitals are uppercase (capital) characters set at the same height as surrounding lowercase (small) letters or text figures. They are used in running text to prevent capitalized words from appearing too large on the page, and as a method of emphasis or distinctiveness for text alongside or instead of italics, or when boldface) is a computer operating system An Operating System is an interface between hardware and user; an OS is responsible for the management and coordination of activities and the sharing of the resources of the computer. The operating system acts as a host for computing applications that are run on the machine. As a host, one of the purposes of an operating system is to handle the originally developed in 1969 by a group of AT&T AT&T Corporation, originally the American Telephone & Telegraph Company, is an American telecommunications company that provided voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During its long history, AT&T was at times the world's largest telephone employees at Bell Labs Bell Laboratories is the research organization of Alcatel-Lucent and previously of the American Telephone & Telegraph Company (AT&T), including Ken Thompson Kenneth Lane Thompson , commonly referred to as Ken Thompson (or simply ken in hacker circles), is an American pioneer of computer science notable for his work with the B programming language and his shepherding of the Unix and Plan 9 operating systems, Dennis Ritchie Dennis MacAlistair Ritchie is an American computer scientist notable for his influence on C and other programming languages, and on operating systems such as Multics and Unix. He received the Turing Award in 1983 and the National Medal of Technology in 1998. Ritchie was the head of Lucent Technologies System Software Research Department when he, Douglas McIlroy Malcolm Douglas McIlroy is a mathematician, engineer, and programmer. As of 2007 he is an Adjunct Professor of Computer Science at Dartmouth College. Dr. McIlroy is best known for having originally developed the Unix pipeline implementation, software componentry and several Unix tools, such as spell, diff, sort, join, graph, speak, and tr, Joe Ossanna Joseph F. Ossanna , received his BSEE from Wayne State University, Detroit, Michigan, in 1952. He was since a member of the Technical Staff of the Bell Telephone Laboratories, Murray Hill, New Jersey. He was actively engaged in the software design of Multics (Multiplexed Information and Computing Service), a general purpose programming system used, and Tom Blakeley. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit A nonprofit organization is an organization that does not distribute its surplus funds to owners or shareholders, but instead uses them to help pursue its goals. Examples of NPOs include charities (i.e. charitable organizations) , trade unions, and public arts organizations. Most governments and government agencies meet this definition, but in organizations.
As of 2007, the owner of the trademark A trademark or trade mark is a distinctive sign or indicator used by an individual, business organization, or other legal entity to identify that the products or services to consumers with which the trademark appears originate from a unique source, and to distinguish its products or services from those of other entities is The Open Group The Open Group is an industry consortium to set vendor- and technology-neutral open standards for computing infrastructure. It was formed when X/Open merged with the Open Software Foundation in 1996. The Open Group is most famous as the certifying body for the UNIX trademark, in the past the group was best known for its publication of the Single, an industry standards consortium. Only systems fully compliant with and certified according to the Single UNIX Specification The Single UNIX Specification is the collective name of a family of standards for computer operating systems to qualify for the name "Unix". The SUS is developed and maintained by the Austin Group, based on earlier work by the IEEE and The Open Group are qualified to use the trademark; others are called "Unix system-like" or "Unix-like A Unix-like operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification".
During the late 1970s and early 1980s, the influence of Unix in academic circles led to large-scale adoption of Unix (particularly of the BSD Berkeley Software Distribution is the UNIX operating system derivative developed and distributed by the Computer Systems Research Group of the University of California, Berkeley, from 1977 to 1995 variant, originating from the University of California, Berkeley The University of California, Berkeley is a public research university located in Berkeley, California, United States. The oldest of the ten major campuses affiliated with the University of California, Berkeley offers some 300 undergraduate and graduate degree programs in a wide range of disciplines. The university occupies 6,651 acres (2,692 ha)) by commercial startups, the most notable of which are Solaris Solaris is a UNIX-based operating system introduced by Sun Microsystems in 1992 as the successor to SunOS, HP-UX HP-UX is Hewlett-Packard's proprietary implementation of the Unix operating system, based on System V (initially System III). It runs on the HP 9000 PA-RISC-based range of processors and HP Integrity Intel's Itanium-based systems, and was also available for later Apollo/Domain systems. Earlier versions also ran on the HP 9000 Series 200, 300, and 4 and AIX AIX is the name given to a series of proprietary operating systems sold by IBM for several of its computer system platforms, based on UNIX System V with 4.3BSD-compatible command and programming interface extensions. Today, in addition to certified Unix systems such as those already mentioned, Unix-like A Unix-like operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification operating systems such as Linux Linux is a generic term referring to Unix-like computer operating systems based on the Linux kernel. Their development is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed by anyone under the terms of the GNU GPL and other free and BSD Berkeley Software Distribution is the UNIX operating system derivative developed and distributed by the Computer Systems Research Group of the University of California, Berkeley, from 1977 to 1995 are commonly encountered. The term "traditional Unix" may be used to describe a Unix or an operating system that has the characteristics of either Version 7 Unix Seventh Edition Unix, also called Version 7 Unix, Version 7 or just V7, was an important early release of the Unix operating system. V7, released in 1979, was the last Bell Laboratories release to see widespread distribution before the commercialization of Unix by AT&T in the early 1980s. V7 was originally developed for Digital Equipment or UNIX System V Unix System V, commonly abbreviated SysV , is one of the versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, termed Releases 1, 2, 3 and 4. System V Release 4, or SVR4, was commercially the most successful version, being the result of an effort,.
