Disk Operating System/360 , also DOS/360 , or simply DOS , is the discontinued first member of a sequence of operating systems for IBM System/360 , System/370 and later mainframes . It was announced by IBM on the last day of 1964, and it was first delivered in June 1966. In its time, DOS/360 was the most widely used operating system in the world.
103-542: The Basic Operating System (BOS) was an early version of DOS and TOS which could provide usable functionality on a system with as little as 8 KB of main storage and one 2311 disk drive. TOS/360 (Tape Operating System/360, not a DOS as such and not so called) was an IBM operating system for the System/360 , used in the early days around 1965 to support the System/360 Model 30 and similar platforms. TOS, as per
206-505: A holding company of manufacturers of record-keeping and measuring systems. It was renamed "International Business Machines" in 1924 and soon became the leading manufacturer of punch-card tabulating systems . During the 1960s and 1970s, the IBM mainframe , exemplified by the System/360 , was the world's dominant computing platform , with the company producing 80 percent of computers in the U.S. and 70 percent of computers worldwide. IBM debuted in
309-575: A neuromorphic CMOS integrated circuit and announced a $ 3 billion investment over the following five years to design a neural chip that mimics the human brain, with 10 billion neurons and 100 trillion synapses, but that uses just 1 kilowatt of power. In 2016, the company launched all-flash arrays designed for small and midsized companies, which includes software for data compression, provisioning, and snapshots across various systems. In January 2019, IBM introduced its first commercial quantum computer: IBM Q System One . In March 2020, it
412-621: A Hollerith department called Hollerith Abteilung, which had IBM machines, including calculating and sorting machines. IBM as a military contractor produced 6% of the M1 Carbine rifles used in World War II, about 346,500 of them, between August 1943 and May. IBM built the Automatic Sequence Controlled Calculator , an electromechanical computer, during World War II. It offered its first commercial stored-program computer,
515-422: A S/360 model 30 with 32KB memory and the decimal instruction set, an IBM 2540 card reader/card punch, an IBM 1403 printer, two or three IBM 2311 disks, two IBM 2415 magnetic tape drives, and the 1052-7 console. The following description applies to DOS/360 except as otherwise noted. Later versions offer additional functionality. Because DOS/360 was designed to run on low-end models of System/360 memory usage
618-573: A System/360 CPU (model 25 and above) with the standard instruction set (decimal and floating-point instruction sets optional). The minimum memory requirement was 16 KB; storage protection was required only if multiprogramming was used. A 1052 Model 7 printer-keyboard, either a selector or multiplexor channel , and at least one disk drive was required — initially a 2311 holding 7.25 MB. A card reader , card punch and line printer were usually included, but magnetic tape drives could be substituted. A typical configuration might consist of
721-609: A boiler, a cold reservoir (a stream of cold water), or a piston (on which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term working body when referring to the system. The biologist Ludwig von Bertalanffy became one of the pioneers of the general systems theory . In 1945 he introduced models, principles, and laws that apply to generalized systems or their subclasses, irrespective of their particular kind,
824-578: A consequence, IBM quickly began losing its market dominance to emerging competitors in the PC market. In 1985, IBM collaborated with Microsoft to develop a new operating system , which was released as OS/2 . Following a dispute, Microsoft severed the collaboration and IBM continued development of OS/2 on its own but it failed in the marketplace against Microsoft's Windows during the mid-1990s. In 1991 IBM began spinning off its many divisions into autonomous subsidiaries (so-called "Baby Blues") in an attempt to make
927-560: A day, compressed the CIL "off-line", and IPLed with the new Core Image Library at the beginning of a business day. A relocatable library for linkable object programs and a source statement library for assembler macros and include text were also supported. Installations could define additional private relocatable and source statement libraries on other disk volumes. DOS/360 had a set of utility programs , an Assembler , and compilers for FORTRAN , COBOL and eventually PL/I , and it supported
1030-657: A fifth company, the Computing-Tabulating-Recording Company (CTR) based in Endicott, New York. The five companies had 1,300 employees and offices and plants in Endicott and Binghamton , New York; Dayton, Ohio ; Detroit, Michigan ; Washington, D.C. ; and Toronto , Canada. Collectively, the companies manufactured a wide array of machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards. Thomas J. Watson, Sr. , fired from
1133-447: A focus on customer service, an insistence on well-groomed, dark-suited salesmen and had an evangelical fervor for instilling company pride and loyalty in every worker". His favorite slogan, " THINK ", became a mantra for each company's employees. During Watson's first four years, revenues reached $ 9 million ($ 158 million today) and the company's operations expanded to Europe, South America, Asia and Australia. Watson never liked

#17330859839471236-444: A major defect: they must be premised on one or more fundamental assumptions upon which additional knowledge is built. This is in strict alignment with Gödel's incompleteness theorems . The Artificial system can be defined as a "consistent formalized system which contains elementary arithmetic". These fundamental assumptions are not inherently deleterious, but they must by definition be assumed as true, and if they are actually false then
1339-449: A pre-generated system containing the OS and the most popular products. SSX was released in 1982, and later replaced by VSE/SP. SSX was sold by IBM as a bundle of 14 component products (Advanced Functions/VSE, VSE/POWER, ACF/VTAME, VSE/VSAM, CICS/DOS/VS, DOS/VS, Sort/Merge, VSE/ICCF, VSE/OCCF, VSE/IPCS, DOS/COBOL, Back Up/Restore, Space Management, VSE/DITTO), and originally would only agree to offer
1442-460: A range of file organizations with access methods to help in using them: Sequential and ISAM files could store either fixed-length or variable-length records, and all types could occupy more than one disk volume. DOS/360 offered Basic Telecommunications Access Method ( BTAM ) and Queued Telecommunications Access Method ( QTAM ). BTAM was primitive and hard to use by later standards, but it allowed communication with almost any type of terminal, which
1545-517: A result of those investments, they were reluctant to commit to such conversion. IBM then needed to continue to offer DOS/360 as an additional operating system. The Hacker's Jargon File incorrectly states that GECOS (also known as GCOS) was copied from DOS/360, which was not the case, however the Xerox Data Systems Xerox Operating System (XOS) was intentionally similar to DOS to simplify program porting. DOS/360 required
1648-616: A separate lawsuit. In 2015, IBM bought the digital part of The Weather Company , Truven Health Analytics for $ 2.6 billion in 2016, and in October 2018, IBM announced its intention to acquire Red Hat for $ 34 billion, which was completed on July 9, 2019. In February 2020, IBM's John Kelly III joined Brad Smith of Microsoft to sign a pledge with the Vatican to ensure the ethical use and practice of Artificial Intelligence (AI) . IBM announced in October 2020 that it would divest
1751-475: A sharp drop in profit margins during the second quarter of fiscal year 1992; market analysts attributed the drop to a fierce price war in the personal computer market over the summer of 1992. The corporate restructuring was one of the largest and most expensive in history up to that point. By the summer of 1993, the IBM PC Co. had divided into multiple business units itself, including Ambra Computer Corporation and
1854-682: A single subsystem in order to test its Specific Application (SA). There are many kinds of systems that can be analyzed both quantitatively and qualitatively . For example, in an analysis of urban systems dynamics , A . W. Steiss defined five intersecting systems, including the physical subsystem and behavioral system. For sociological models influenced by systems theory, Kenneth D. Bailey defined systems in terms of conceptual , concrete , and abstract systems, either isolated , closed , or open . Walter F. Buckley defined systems in sociology in terms of mechanical , organic , and process models . Bela H. Banathy cautioned that for any inquiry into
1957-570: A spooler called GRASP . DOS/360 had no relocating loader , so programmers had to link edit a separate executable version of each program for each partition, or address space, in which the program was likely to be run. Alternatively assembler-language programs could be written as self-relocating , but that imposed additional complexity and a size penalty, albeit a small one. Large DOS shops with multiple machines and multiple partition layouts often wrote their own relocating loader to circumvent this issue. The DOS/360 application programming interface
2060-665: A system is the Universe . An open system can also be viewed as a bounded transformation process, that is, a black box that is a process or collection of processes that transform inputs into outputs. Inputs are consumed; outputs are produced. The concept of input and output here is very broad. For example, an output of a passenger ship is the movement of people from departure to destination. A system comprises multiple views . Human-made systems may have such views as concept, analysis , design , implementation , deployment, structure, behavior, input data, and output data views. A system model
2163-582: A system understanding its kind is crucial, and defined natural and designed , i. e. artificial, systems. For example, natural systems include subatomic systems, living systems , the Solar System , galaxies , and the Universe , while artificial systems include man-made physical structures, hybrids of natural and artificial systems, and conceptual knowledge. The human elements of organization and functions are emphasized with their relevant abstract systems and representations. Artificial systems inherently have
SECTION 20
#17330859839472266-481: A system wide total of fifteen subtasks. DOS/VS was succeeded by DOS/VSE through z/VSE . DOS/VSE was introduced in 1979 as an "extended" version of DOS/VS to support the new 4300 processors. The 4300 systems included a feature called ECPS:VSE that provided a single-level storage for both the processor and the I/O channels. DOS/VSE provided support for ECPS:VSE, but could also run on a System/370 without that feature. VSE
2369-456: Is George Boole 's Boolean operators. Other examples relate specifically to philosophy, biology, or cognitive science. Maslow's hierarchy of needs applies psychology to biology by using pure logic. Numerous psychologists, including Carl Jung and Sigmund Freud developed systems that logically organize psychological domains, such as personalities, motivations, or intellect and desire. In 1988, military strategist, John A. Warden III introduced
2472-495: Is a publicly traded company and one of the 30 companies in the Dow Jones Industrial Average . IBM is the largest industrial research organization in the world, with 19 research facilities across a dozen countries, having held the record for most annual U.S. patents generated by a business for 29 consecutive years from 1993 to 2021. IBM was founded in 1911 as the Computing-Tabulating-Recording Company (CTR),
2575-534: Is a hardware system, software system , or combination, which has components as its structure and observable inter-process communications as its behavior. There are systems of counting, as with Roman numerals , and various systems for filing papers, or catalogs, and various library systems, of which the Dewey Decimal Classification is an example. This still fits with the definition of components that are connected together (in this case to facilitate
2678-542: Is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences . Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. The term system comes from the Latin word systēma , in turn from Greek σύστημα systēma : "whole concept made of several parts or members, system", literary "composition". In

A version with multitasking, supporting up to three memory partitions , requiring 32 KB of memory was later released. Despite its limitations, DOS/360 became the most widely used operating system for processors with less than 256 KB of memory because: System/360 hardware sold very well; DOS/360 ran well on System/360 processors which medium-sized organizations could afford; and it
7107-575: The mid-1950s. There are two other IBM buildings within walking distance of CHQ: the North Castle office, which previously served as IBM's headquarters; and the Louis V. Gerstner, Jr., Center for Learning (formerly known as IBM Learning Center (ILC)), a resort hotel and training center, which has 182 guest rooms, 31 meeting rooms, and various amenities. IBM operates in 174 countries as of 2016 , with mobility centers in smaller market areas and major campuses in
7210-600: The middleware built on top of those such as the CICS transaction processing monitor, had a near-monopoly-level market share and became the thing IBM was most known for during this period. In 1969, the United States of America alleged that IBM violated the Sherman Antitrust Act by monopolizing or attempting to monopolize the general-purpose electronic digital computer system market, specifically computers designed primarily for business, and subsequently alleged that IBM violated
7313-447: The most powerful in the world in the 21st century. As one of the world's oldest and largest technology companies, IBM has been responsible for several technological innovations , including the automated teller machine (ATM), dynamic random-access memory (DRAM), the floppy disk , the hard disk drive , the magnetic stripe card , the relational database , the SQL programming language , and
7416-409: The nature of their component elements, and the relation or 'forces' between them. In the late 1940s and mid-50s, Norbert Wiener and Ross Ashby pioneered the use of mathematics to study systems of control and communication , calling it cybernetics . In the 1960s, Marshall McLuhan applied general systems theory in an approach that he called a field approach and figure/ground analysis , to
7519-464: The notion of organizations as systems in his book The Fifth Discipline . Organizational theorists such as Margaret Wheatley have also described the workings of organizational systems in new metaphoric contexts, such as quantum physics , chaos theory , and the self-organization of systems . There is also such a thing as a logical system . An obvious example is the calculus developed simultaneously by Leibniz and Isaac Newton . Another example
7622-501: The number of partitions to be set at IPL (Initial Program Load), the IBM term for Boot load. Executable programs were stored in a Core Image Library . While running, DOS could not reclaim space as programs were deleted or replaced with newer versions. When the Core Image Library became full, it had to be compressed by a utility program, and this could halt development work until it was complete. Many shops simply froze changes for
7725-400: The parent company of Sesame Street , and Salesforce.com . In 2015, its chip division transitioned to a fabless model with semiconductors design, offloading manufacturing to GlobalFoundries . In 2015, IBM announced three major acquisitions: Merge Healthcare for $ 1 billion, data storage vendor Cleversafe , and all digital assets from The Weather Company , including Weather.com and
7828-471: The program accessing the device, at the time of the error. Like OS/360 , initial releases of DOS could run only one program at a time. Later versions of "real" DOS were able to run up to three programs concurrently, in separate memory partitions, supported by the same hardware memory protection features of the more scalable OS/360 operating system. These were identified as BG ( background ), F1 ( foreground 1 ) and F2 ( foreground 2 ). Multiprogramming
7931-405: The role of individual agency in social interactions. Systems-based models of international relations also underlie the vision of the international sphere held by the liberal institutionalist school of thought, which places more emphasis on systems generated by rules and interaction governance, particularly economic governance. In computer science and information science , an information system
8034-407: The study of media theory . In the 1980s, John Henry Holland , Murray Gell-Mann and others coined the term complex adaptive system at the interdisciplinary Santa Fe Institute . Systems theory views the world as a complex system of interconnected parts. One scopes a system by defining its boundary ; this means choosing which entities are inside the system and which are outside—part of
8137-414: The supervisor run in 64-bit mode, it only provides 31-bit virtual address spaces to problem state applications. As of 2011 one estimate placed the number of sites using z/VSE at around 4,000. When developing a new hardware generation of unified System/360 (or S/360) computers, IBM had originally committed to delivering a single operating system, OS/360 , also compatible with low-end machines; but hardware
8240-1207: The system is not as structurally integral as is assumed (i.e. it is evident that if the initial expression is false, then the artificial system is not a "consistent formalized system"). For example, in geometry this is very evident in the postulation of theorems and extrapolation of proofs from them. George J. Klir maintained that no "classification is complete and perfect for all purposes", and defined systems as abstract, real, and conceptual physical systems , bounded and unbounded systems , discrete to continuous, pulse to hybrid systems , etc. The interactions between systems and their environments are categorized as relatively closed and open systems . Important distinctions have also been made between hard systems—–technical in nature and amenable to methods such as systems engineering , operations research, and quantitative systems analysis—and soft systems that involve people and organizations, commonly associated with concepts developed by Peter Checkland and Brian Wilson through soft systems methodology (SSM) involving methods such as action research and emphasis of participatory designs. Where hard systems might be identified as more scientific ,
8343-527: The system. The parts of a system must be related; they must be "designed to work as a coherent entity"—otherwise they would be two or more distinct systems. Most systems are open systems , exchanging matter and energy with their respective surroundings; like a car, a coffeemaker , or Earth . A closed system exchanges energy, but not matter, with its environment; like a computer or the project Biosphere 2 . An isolated system exchanges neither matter nor energy with its environment. A theoretical example of such
8446-532: The time the biggest in American corporate history. Lou Gerstner was hired as CEO from RJR Nabisco to turn the company around. In 1995, IBM purchased Lotus Software , best known for its Lotus 1-2-3 spreadsheet software. During the decade, IBM was working on a new operating system, named the Workplace OS project. Despite a large amount of money spent on the project, it was cancelled in 1996. In 1998, IBM merged
8549-1003: The universe that is being studied (of which a thermodynamic system is one major example). Engineering also has the concept of a system referring to all of the parts and interactions between parts of a complex project. Systems engineering is the branch of engineering that studies how this type of system should be planned, designed, implemented, built, and maintained. Social and cognitive sciences recognize systems in models of individual humans and in human societies. They include human brain functions and mental processes as well as normative ethics systems and social and cultural behavioral patterns. In management science , operations research and organizational development , human organizations are viewed as management systems of interacting components such as subsystems or system aggregates, which are carriers of numerous complex business processes ( organizational behaviors ) and organizational structures. Organizational development theorist Peter Senge developed
8652-608: The vacuum tube based IBM 701 , in 1952. The IBM 305 RAMAC introduced the hard disk drive in 1956. The company switched to transistorized designs with the 7000 and 1400 series, beginning in 1958. In which, IBM considered the 1400 series the ''model T'' of computing, due to it being the first computer with over ten thousand sales by IBM. In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie , New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957,
8755-411: Was a 31-bit DOS/VSE version, which was released in 1990 with support for up to 384 MB of real storage. It provided up to twelve static partitions and allowed VSE/POWER and ACF/VTAM to be run in private address spaces . It introduced a new feature called dynamic partitions which could allow up to 150 concurrent jobs, each in its own address space. Version 1 could run in either ESA or 370 mode, with
8858-409: Was a big advantage at a time when there was little standardization of communications protocols. The simplicity of its API also allowed the relatively easy interface of external communications processors, which facilitated DOS/360 machines becoming nodes in the multi-tier networks of large organizations. Conversely, QTAM users did not need as much knowledge about individual devices because QTAM operated at
8961-482: Was a concern. It was possible to generate a DOS supervisor , the resident portion of the operating system, as small as 5902 bytes. Detailed charts listed memory requirements for each sysgen option, often as little as 100 bytes. A minimum system would leave just over 10 KB of storage available for a single batch partition which was enough to run utilities and all compilers except COBOL , PL/I , and full FORTRAN IV . To keep memory usage as small as possible, DOS
9064-476: Was acquired by Clayton & Dubilier in a leveraged buyout shortly after its formation. In September 1992, IBM completed the spin-off of their various non-mainframe and non-midrange, personal computer manufacturing divisions, combining them into an autonomous wholly owned subsidiary known as the IBM Personal Computer Company (IBM PC Co.). This corporate restructuring came after IBM reported
9167-526: Was already available and the OS/360 project fell further and further behind schedule, as described at length by Fred Brooks in The Mythical Man-Month . IBM was forced to quickly develop four additional systems: When OS/360 was finally released, a year late, it required at least 64 KB of memory. DOS was designed to use little memory, and could run on 16 KB machines, a configuration available on
9270-425: Was an optional feature of DOS/360, selectable at system generation . A later SYSGEN option allowed batch operation run in either FG partition. Otherwise foreground programs had to be manually started by the computer operator . DOS/VS allowed up to seven concurrent programs, although five or six was a more common number due to the smaller scale of the hardware usually hosting DOS systems. Both DOS and DOS/VS allow
9373-534: Was announced that IBM will build Europe's first quantum computer in Ehningen, Germany . The center, to be operated by the Fraunhofer Society , was still in construction as of 2023, with cloud access planned in 2024. System A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment ,
9476-480: Was better than the "operating systems" these customers had before. DOS/360 was the operating system which filled the time gap between the announcement of the System/360 and the availability of the intended operating system, OS/360. As a result of the delay, a number of customers implemented DOS systems and committed significant investments to run them. IBM expected that DOS/360 users would soon upgrade to OS/360, but as
9579-432: Was coded entirely in assembly language . The concept of transient area is part of Mythical Man-Month 's discussion on design and the use of main memory. To further reduce memory usage, the supervisor employed overlays called transients that were read into one of two reserved transient areas as required. The use of $ $ A and $ $ B prefixes ensured rapid loading of transients because their names were stored first in
9682-448: Was completely out of IBM. IBM is headquartered in Armonk, New York , a community 37 miles (60 km) north of Midtown Manhattan. A nickname for the company is the " Colossus of Armonk ". Its principal building, referred to as CHQ, is a 283,000-square-foot (26,300 m ) glass and stone edifice on a 25-acre (10 ha) parcel amid a 432-acre former apple orchard the company purchased in
9785-400: Was exhibited on Jeopardy! where it won against game-show champions Ken Jennings and Brad Rutter. The company also celebrated its 100th anniversary in the same year on June 16. In 2012, IBM announced it had agreed to buy Kenexa and Texas Memory Systems, and a year later it also acquired SoftLayer Technologies, a web hosting service , in a deal worth around $ 2 billion. Also that year,
9888-475: Was incompatible with OS/360. High level language programs written for DOS needed to be compiled and linked before they could be used with OS/360. Minor differences between compilers of DOS as opposed to OS sometimes required modifications to programs. The port in the other direction however was more challenging. Since OS/360 had significantly more features supported in its API, any use of those features would have to be removed from programs being ported to DOS. This
9991-485: Was less of a problem for programmers working in high level languages such as COBOL . Assembler programs, on the other hand, tended to utilize those very features more often and usually needed greater modification to run on DOS. IBM International Business Machines Corporation (using the trademark IBM ), nicknamed Big Blue , is an American multinational technology company headquartered in Armonk, New York and present in over 175 countries. It
10094-633: Was originally part of the joint venture and was sold by LG in 2012. Continuing a trend started in the 1990s of downsizing its operations and divesting from commodity production , IBM sold all of its personal computer business to Chinese technology company Lenovo and, in 2009, it acquired software company SPSS Inc. Later in 2009, IBM's Blue Gene supercomputing program was awarded the National Medal of Technology and Innovation by U.S. President Barack Obama . In 2011, IBM gained worldwide attention for its artificial intelligence program Watson , which
10197-497: Was recognized with the 1990 Honor Award from the National Building Museum . IBM has a large and diverse portfolio of products and services. As of 2016 , these offerings fall into the categories of cloud computing , artificial intelligence, commerce , data and analytics , Internet of things (IoT), IT infrastructure , mobile , digital workplace and cybersecurity . Since 1954, IBM sells mainframe computers ,
10300-499: Was released in 1972. The first DOS/VS release was numbered "Release 28" to signify an incremental upgrade from DOS/360. It added virtual memory in support of the new System/370 series hardware. It used a fixed page table which mapped a single address space of up to 16 megabytes for all partitions combined. DOS/VS increased the number of partitions (separate simultaneous programs) from three (named Background, Foreground 1 and Foreground 2) to five (BG and F1 through F4) and allowed
10403-435: Was significantly more cryptic than OS/360 keyword-driven job control. Early DOS included no spooling sub-system to improve the efficiency of punched card and line printer I/O. By the late 1960s both IBM and aftermarket vendors began filling this void. IBM's spooler was an option called Priority Output Writers, Execution processors and input Readers (POWER) , and Software Design, Inc., an independent software company, sold
10506-457: Was the last free version of DOS. VSE/Advanced Functions (VSE/AF), prepared for 1983 delivery, added new device support and functionality to DOS/VSE. Many installations ran VSE/AF using products such as VSE System Installation Productivity Option/Extended (VSE System IPO/E), which combined DOS/VSE, VSE/AF and various other products. SSX/VSE ("Small System Executive") was an attempt by IBM to simplify purchase and installation of VSE by providing
10609-480: Was valued at over $ 153 billion as of May 2024. Despite its relative decline within the technology sector, IBM remains the seventh largest technology company by revenue, and 67th largest overall company by revenue in the United States . IBM ranked No. 38 on the 2020 Fortune 500 rankings of the largest United States corporations by total revenue. In 2014, IBM was accused of using "financial engineering" to hit its quarterly earnings targets rather than investing for
