Chronology
Chronology (from Latin ''chronologia'', from Ancient Greek , ''chrónos'', "time"; and , '' -logia'') is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".Memidex/WordNet, "chronology,memidex.com (accessed September 25, 2010). Chronology is a part of periodization. It is also a part of the discipline of history including earth history, the earth sciences, and study of the geologic time scale. Related fields Chronology is the science of locating historical events in time. It relies upon chronometry, which is also known as timekeeping, and historiography, which examines the writing of history and the use of historical methods. Radiocarbon dating estimates the age of formerly living things by measuring the proportion of carbon-14 isotope in their carbon content. Dendrochronology estimates the age of trees by corre ...

University Of Michigan Executive System
The University of Michigan Executive System, or UMES, a batch operating system developed at the University of Michigan in 1958, was widely used at many universities. Based on the General Motors Executive System for the IBM 701, UMES was revised to work on the mainframe computers in use at the University of Michigan during this time (IBM 704, 709, and 7090) and to work better for the small student jobs that were expected to be the primary work load at the University. UMES was in use at the University of Michigan until 1967, when MTS was phased in to take advantage of the newer virtual memory time-sharing technology that became available on the IBM System/360 Model 67.

English Electric KDF9
KDF9 was an early British 48-bit computer designed and built by English Electric (which in 1968 was merged into International Computers Limited (ICL)). The first machine came into service in 1964 and the last of 29 machines was decommissioned in 1980 at the National Physical Laboratory. The KDF9 was designed for, and used almost entirely in, the mathematical and scientific processing fields in 1967, nine were in use in UK universities and technical colleges. The KDF8, developed in parallel, was aimed at commercial processing workloads. The KDF9 was an early example of a machine that directly supported multiprogramming, using offsets into its core memory to separate the programs into distinct virtual address spaces. Several operating systems were developed for the platform, including some that provided fully interactive use through PDP-8 machines acting as smart terminal servers. A number of compilers were available, notably both checkout and globally optimizing compilers for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titan (1963 Computer)
Titan was the prototype of the Atlas 2 computer developed by Ferranti and the University of Cambridge Mathematical Laboratory in Cambridge, England. It was designed starting in 1963, and in operation from 1964 to 1973. History In 1961, the University of Cambridge found itself unable to fund a suitably powerful computer for its needs at the time, so the University purchased from Ferranti the main Atlas processing units and then jointly designed the memory and peripheral equipment. The joint effort led to a cheaper and simpler version of the Atlas that Ferranti could market, leaving Cambridge with the prototype version, named Titan. The Atlas hardware arrived in Cambridge in 1963, although software design was already underway. David Wheeler was in charge of the joint effort between the University and Ferranti. In 1965 the Cambridge side of the team decided to add a time-sharing facility for Titan, necessitating the acquisition of additional hardware. When Titan came into full se ...

AN/FSQ-32
The AN/FSQ-32 SAGE Solid State Computer (AN/FSQ-7A before December 1958, colloq. "Q-32") was a planned military computer central for deployment to Super Combat Centers in nuclear bunkers and to some above-ground military installations. In 1958, Air Defense Command planned to acquire 13 Q-32 centrals for several Air Divisions/Sectors. Background In 1956, ARDC sponsored "development of a transistorized, or solid-state, computer" by IBM and when announced in June 1958, the planned "SAGE Solid State Computer...was estimated to have a computing capability of seven times" the AN/FSQ-7. ADC's November 1958 plan to field—by April 1964—the 13 solid state AN/FSQ-7A was for each to network "a maximum of 20 long-range radar inputs 0 LRI telephone linesand a maximum dimension of just over 1000 miles in both north-south and east-west directions." "Low rate Teletype data" could be accepted on 32 telephone lines (e.g., from "Alert Network Number 1"). On 17 November 1958, CINCNORAD "de ...

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

General Comprehensive Operating System
General Comprehensive Operating System (GCOS, ; originally GECOS, General Electric Comprehensive Operating Supervisor) is a family of operating systems oriented toward the 36-bit GE/Honeywell mainframe computers. The original version of GCOS was developed by General Electric beginning in 1962. The operating system is still used today in its most recent versions (GCOS 7 and GCOS 8) on servers and mainframes produced by Groupe Bull, primarily through emulation, to provide continuity with legacy mainframe environments. GCOS 7 and GCOS 8 are separate branches of the operating system and continue to be developed alongside each other. History GECOS The GECOS operating system was developed by General Electric for the 36-bit GE-600 series in 1962–1964; GE released GECOS I (with a prototype 635) in April 1965, GECOS II in November 1965 and GECOS III (with time-sharing) in 1967. It bore a close resemblance architecturally to IBSYS on the IBM 7094 and less to DOS/360 on the System/360 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBN Time-Sharing System
The BBN Time-Sharing System was an early time-sharing system created at Bolt, Beranek and Newman (BBN) for the PDP-1 computer. It began operation in September 1962. History J. C. R. Licklider left MIT to become a vice president at Bolt Beranek and Newman in 1957. He learned about time-sharing from Christopher Strachey at a UNESCO-sponsored conference on Information Processing in Paris in June 1959. Digital Equipment Corporation's prototype PDP-1 was ready in November, 1959, and the machine was featured in the November/December issue of ''Datamation'' magazine. BBNer Ed Fredkin saw a prototype system at the Eastern Joint Computer Conference in Boston in December 1959, and was extremely interested. Given BBN's interest, DEC's founder and President Ken Olsen visited and explained that DEC had just completed construction of a prototype PDP-1, and that they needed a test site for a month. BBN agreed to be the test site, at its regular hourly rates, and then in early 1960 obtained t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burroughs Corporation
The Burroughs Corporation was a major American manufacturer of business equipment. The company was founded in 1886 as the American Arithmometer Company. In 1986, it merged with Sperry UNIVAC to form Unisys. The company's history paralleled many of the major developments in computing. At its start, it produced mechanical adding machines, and later moved into programmable ledgers and then computers. It was one of the largest producers of mainframe computers in the world, also producing related equipment including typewriters and printers. Early history In 1886, the American Arithmometer Company was established in St. Louis, Missouri, to produce and sell an adding machine invented by William Seward Burroughs (grandfather of Beat Generation author William S. Burroughs). In 1904, six years after Burroughs' death, the company moved to Detroit and changed its name to the Burroughs Adding Machine Company. It was soon the biggest adding machine company in America. Evolving product ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burroughs MCP
The MCP (Master Control Program) is the operating system of the Burroughs small, medium and large systems, including the Unisys Clearpath/MCP systems. MCP was originally written in 1961 in ESPOL (Executive Systems Problem Oriented Language). In the 1970s, MCP was converted to NEWP which was a better structured, more robust, and more secure form of ESPOL. The MCP was a leader in many areas, including: the first operating system to manage multiple processors, the first commercial implementation of virtual memory, and the first OS written exclusively in a high-level language. History In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System (B5000 and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961. Unlike IBM, which faced hardware competition af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compatible Time-Sharing System
The Compatible Time-Sharing System (CTSS) was the first general purpose time-sharing operating system. Compatible Time Sharing referred to time sharing which was compatible with batch processing; it could offer both time sharing and batch processing concurrently. CTSS was developed at the MIT Computation Center ("Comp Center"). CTSS was first demonstrated on MIT's modified IBM 709 in November 1961. The hardware was replaced with a modified IBM 7090 in 1962 and later a modified IBM 7094 called the "blue machine" to distinguish it from the Project MAC CTSS IBM 7094. Routine service to MIT Comp Center users began in the summer of 1963 and was operated there until 1968. A second deployment of CTSS on a separate IBM 7094 that was received in October 1963 (the "red machine") was used early on in Project MAC until 1969 when the red machine was moved to the Information Processing Center and operated until July 20, 1973. CTSS ran on only those two machines however there were remote CTSS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
