Open Software FoundationThe Open Software Foundation, Inc. (OSF) was a not-for-profit industry consortium for creating an open standard for an implementation of the operating systemUnix. It was formed in 1988 and merged with X/Open in 1996, to become The Open Group. Despite the similarities in name, OSF was unrelated to the Free Software Foundation (FSF), or the Open Source Initiative (OSI).
Common Open Software EnvironmentThe Common Open Software Environment (COSE) was an initiative formed in March 1993 by the major Unix vendors of the time to create open, unified operating system (OS) standards. BackgroundThe COSE process was established during a time when the "Unix wars" had become an impediment to the growth of Unix. Microsoft, already dominant on the corporate desktop, was beginning to make a bid for two Unix strongholds: technical workstations and the enterprise data center.
X/OpenX/Open group (also known as the Open Group for Unix Systems and incorporated in 1987 as X/Open Company, Ltd.) was a consortium founded by several European UNIX systems manufacturers in 1984 to identify and promote open standards in the field of information technology. More specifically, the original aim was to define a single specification for operating systems derived from UNIX, to increase the interoperability of applications and reduce the cost of porting software.
Unix warsThe Unix wars were a struggle between vendors to set a standard for the Unixoperating system in the late 1980s and early 1990s. OriginsBoth AT&T Corporation and University of California, Berkeley are important in the early history of Unix. Although AT&T's Bell Labs created Unix, by the 1980s, Berkeley's Computer Systems Research Group was the leading non-commercial Unix developer.
The Open GroupGlobal standards consortium The Open Group is a global consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications." It has 900+ member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development. It was established in 1996 when X/Open merged with the Open Software Foundation.
Operating systemSoftware that manages computer hardware resourcesAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.
Sun MicrosystemsAmerican computer company, 1982–2010Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer hardware, software, and information technology services. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing.
UnixUnix ( , YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, the development of which started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
AT&TAmerican telecommunications companyAT&T Inc., an abbreviation of its predecessor's original name, the American Telephone and Telegraph Company, is an American multinationaltelecommunications company headquartered at the Whitacre Tower in Downtown Dallas, Texas. AT&T is the world's third-largest telecommunications company by revenue, the third-largest wireless carrier in the United States behind T-Mobile and Verizon, and the nation's largest fiber internet provider.
OSF/1OSF/1 is a variant of the Unixoperating system developed by the Open Software Foundation during the late 1980s and early 1990s. OSF/1 is one of the first operating systems to have used the Mach kernel developed at Carnegie Mellon University, and is probably best known as the native Unix operating system for DEC Alpha architecture systems.
Motif (software)Motif is a graphical user interface (GUI) widget toolkit for Unix-like operating systems using X11. Motif's look and feel is distinguished by its use of rudimentary square and chiseled three-dimensional effects for its various user interface elements. Closely related to Motif is the Motif Window Manager (MWM). Motif is the toolkit for the Common Desktop Environment (CDE) and thus became the standard widget toolkit for the commercial UNIXes that adopted CDE.
Tru64 UNIXTru64 UNIX is a discontinued 64-bitUNIXoperating system for the Alphainstruction set architecture (ISA), currently owned by Hewlett-Packard (HP). Previously, Tru64 UNIX was a product of Compaq, and before that, Digital Equipment Corporation (DEC), where it was known as Digital UNIX (originally DEC OSF/1 AXP). As its original name suggests, Tru64 UNIX is based on the OSF/1 operating system. DEC's previous UNIX product was known as Ultrix and was based on BSD.*As an Amazon Associate I earn from qualifying purchases.
