George E. Felton
George Eric Felton (3 February 1921 – 14 June 2019) was a British computer scientist. He undertook pioneering work in the field of operating systems and programming software and is the father of the GEORGE Operating System. He held the world record for the computation of π. Early life, education, and military service George Felton was born in Paris in 1921 to English parents - his mother, Muriel Felton, worked at Bletchley Park during the war. He was brought up in Paris and Menton but moved to England following the early death of his father. Felton attended Bedford School and Magdalene College, Cambridge where he read the Mathematical Tripos. His university studies were interrupted by World War II during which Felton joined the RAF with a commission. Exploiting his interest in electronics he served as a Radar engineer and instructor. He was demobilised and returned to Cambridge in 1946. At Cambridge he met his wife Ruth Felton at meetings of The Round Country Dance society ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Demobilised
Demobilization or demobilisation (see spelling differences) is the process of standing down a nation's armed forces from combat-ready status. This may be as a result of victory in war, or because a crisis has been peacefully resolved and military force will not be necessary. The opposite of demobilization is mobilization. Forceful demobilization of a defeated enemy is called demilitarization. The United Nations defined demobilization as "a multifaceted process that officially certifies an individual's change of status from being a member of a military grouping of some kind to being a civilian". Persons undergoing demobilization are removed from the command and control of their armed force and group and the transformation from a military mindset to that of a civilian begins. Although combatants become civilians when they acquire their official discharge documents the mental connection and formal ties to their military command structure still exist. To prevent soldiers from rejoini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows NT
Windows NT is a proprietary graphical operating system An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also in ... produced by Microsoft, the first version of which was released on July 27, 1993. It is a processor-independent, multiprocessing and multi-user operating system. The first version of Windows NT was Windows NT 3.1 and was produced for workstations and server computers. It was a commercially focused operating system intended to complement consumer versions of Microsoft Windows, Windows that were based on MS-DOS (including Windows 1.0 through Windows 3.1x). Gradually, the Windows NT family was expanded into Microsoft's general-purpose operating system product line for all personal computers, deprecating the Windows 9x family.

Royal Photographic Society
The Royal Photographic Society of Great Britain, commonly known as the Royal Photographic Society (RPS), is one of the world's oldest photographic societies. It was founded in London, England, in 1853 as the Photographic Society of London with the objective of promoting the art and science of photography, and in 1853 received Monarchy of the United Kingdom, royal patronage from Queen Victoria and Albert, Prince Consort, Prince Albert. A change to the society's name to reflect the patronage was, however, not considered expedient at the time. In 1874, it was renamed the Photographic Society of Great Britain, and only from 1894 did it become known as the Royal Photographic Society of Great Britain, a title which it continues to use today. On 25 June 2019, the Duchess of Cambridge, now Catherine, Princess of Wales, became the Society's Patron, taking over from Queen Elizabeth II who had been patron since 1952. A registered Charitable organization, charity since 1962, in July 2004, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlas Computer (Manchester)
The Atlas Computer was one of the world's first supercomputers, in use from 1962 (when it was claimed to be the most powerful computer in the world) to 1972. Atlas' capacity promoted the saying that when it went offline, half of the United Kingdom's computer capacity was lost. It is notable for being the first machine with virtual memory (at that time referred to as 'one-level store') using paging techniques; this approach quickly spread, and is now ubiquitous. Atlas was a second-generation computer, using discrete germanium transistors. Atlas was created in a joint development effort among the University of Manchester, Ferranti International plc and the Plessey Co., plc. Two other Atlas machines were built: one for British Petroleum and the University of London, and one for the Atlas Computer Laboratory at Chilton near Oxford. A derivative system was built by Ferranti for Cambridge University. Called the Titan, or Atlas 2, it had a different memory organisation and ran ...

Spooling
In computing, spooling is a specialized form of multi-programming for the purpose of copying data between different devices. In contemporary systems, it is usually used for mediating between a computer application and a slow peripheral, such as a printer. Spooling allows programs to "hand off" work to be done by the peripheral and then proceed to other tasks, or to not begin until input has been transcribed. A dedicated program, the spooler, maintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. Conversely, for slow ''input'' peripherals, such as a card reader, a spooler can maintain a sequence of computational jobs waiting for data, starting each job when all of the relevant input is available; see batch processing. The spool itself refers to the sequence of jobs, or the storage area where they are held. In many cases, the spooler is able to drive devices at their full rated speed with minimal impact on other processing. Spooling is a co ...

Autopilot
An autopilot is a system used to control the path of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines. An autopilot system is sometimes colloquially referred to as ''"George"'' (e.g. ''"we'll let George fly for a while"''). The etymology of the nickname is unclear: some claim it is a reference to inventor George De Beeson, who patented an autopilot in the 1930s, while others claim that Royal Air Force pilots coined the term during World War II to symbolize that their aircraft technically belonged to King George VI. First autopilots In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICT 1900 Series
ICT 1900 was a family of mainframe computers released by International Computers and Tabulators (ICT) and later International Computers Limited (ICL) during the 1960s and 1970s. The 1900 series was notable for being one of the few non-American competitors to the IBM System/360, enjoying significant success in the European and British Commonwealth markets. Origins In early 1963, ICT was engaged in negotiations to buy the computer business of Ferranti. In order to sweeten the deal, Ferranti demonstrated to ICT the Ferranti-Packard 6000 (FP6000) machine, which had been developed by its Canadian subsidiary Ferranti-Packard, to a design known as Harriac that had been initiated in Ferranti by Harry Johnson and fleshed out by Stanley Gill and John Iliffe. The FP6000 was an advanced design, notably including hardware support for multiprogramming. ICT considered using the FP6000 as their medium-sized processor in the 1965–1968 timeframe, replacing the ICT 1302. Another plan ...

LEO (computer)
The LEO I (Lyons Electronic Office I) was the first computer used for commercial business applications. The prototype LEO I was modelled closely on the Cambridge EDSAC. Its construction was overseen by Oliver Standingford, Raymond Thompson and David Caminer of J. Lyons and Co. LEO I ran its first business application in 1951. In 1954 Lyons formed LEO Computers Ltd to market LEO I and its successors LEO II and LEO III to other companies. LEO Computers eventually became part of English Electric Company (EEL), (EELM), then English Electric Computers (EEC), where the same team developed the faster LEO 360 and even faster LEO 326 models. It then passed to International Computers Limited (ICL) and ultimately Fujitsu. LEO series computers were still in use until 1981. Origins and initial design J. Lyons and Co. was one of the UK's leading catering and food manufacturing companies in the first half of the 20th century. In 1947, they sent two of its ...

International Computers And Tabulators
International Computers and Tabulators or ICT was a British computer manufacturer, formed in 1959 by a merger of the British Tabulating Machine Company (BTM) and Powers-Samas. In 1963 it acquired the business computer divisions of Ferranti. It exported computers to many countries and in 1968 became part of International Computers Limited (ICL). Products The ICT 1101 was known as the EMIDEC 1100 computer before the acquisition of the EMI Computing Services Division who designed and produced it. The ICT 1201 computer used thermionic valve technology and its main memory was drum storage. Input was from 80-column punched cards and output was to 80-column cards and a printer. Before the merger, under BTM, this had been known as the HEC4 (Hollerith Electronic Computer, fourth version). The drum memory held 1K of 40-bit words. The computer was programmed using binary machine code instructions. When programming the 1201, the machine code instructions were not sequential but were ...
