Eton College
Eton College () is a Public school (United Kingdom), public school in Eton, Berkshire, England. It was founded in 1440 by Henry VI of England, Henry VI under the name ''Kynge's College of Our Ladye of Eton besyde Windesore'',Nevill, p. 3 ff. intended as a sister institution to King's College, Cambridge, making it the 18th-oldest Headmasters' and Headmistresses' Conference (HMC) school. Eton is particularly well-known for its history, wealth, and notable alumni, called :People educated at Eton College, Old Etonians. Eton is one of only three Public school (United Kingdom)#21st century, public schools, along with Harrow School, Harrow (1572) and Radley College, Radley (1847), to have retained the boys-only, boarding-only tradition, which means that its boys live at the school seven days a week. The remainder (such as Rugby School, Rugby in 1976, Charterhouse School, Charterhouse in 1971, Westminster School, Westminster in 1973, and Shrewsbury School, Shrewsbury in 2015) have sinc ...

Clock Speed
In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are used to synchronize the operations of its components, and is used as an indicator of the processor's speed. It is measured in the SI unit of frequency hertz (Hz). The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz). This metric is most useful when comparing processors within the same family, holding constant other features that may affect performance. Determining factors Binning Manufacturers of modern processors typically charge premium prices for processors that operate at higher clock rates, a practice called binning. For a given CPU, the clock rates are determined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn Archimedes
Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, England. The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS. The first models were introduced in 1987, and systems in the Archimedes family were sold until the mid-1990s. ARM's RISC design, a 32-bit CPU (using 26-bit addressing), running at 8 MHz, was stated as achieving 4.5+ MIPS, which provided a significant upgrade from 8-bit home computers, such as Acorn's previous machines. Claims of being the fastest micro in the world and running at 18 MIPS were also made during tests. Two of the first models—the A305 and A310—were given the BBC branding, with BBC Enterprises regarding the machines as "a continuing part of the original computer literacy project". Dissatisfaction with the branding arrangement was voiced by competitor Research Machines and an industry group led by a Microsoft representative, ...

Acorn User
''Acorn User'' magazine was founded by Acorn Computers in 1982, contract-published by Addison-Wesley, to coincide with the launch of the BBC Micro. It covered the range of Acorn home computers, the BBC Micro and Atom at first and later the Electron, Archimedes and Risc PC. History The first issue was dated July/August 1982. From the April 1984 issue, the magazine came under the control of Redwood Publishing, a company recently founded by Michael Potter (a former publisher at Haymarket Publishing), Christopher Ward (a former editor of the ''Daily Express'' and a non-executive director of Acorn) and Chris Curry (one of the founders of Acorn). In 1989, the name changed to ''BBC Acorn User'', reflecting the fact that the commercial arm of the BBC, BBC Enterprises, took control of Redwood to expand its publishing activities. The magazine lost the BBC branding when it was sold to Europress, publisher of rival title ''Acorn Computing'', coinciding with its January 1994 issue. The ...

BBC Master
The BBC Master is a home computer released by Acorn Computers in early 1986. It was designed and built for the British Broadcasting Corporation (BBC) and was the successor to the BBC Micro Model B. The Master 128 remained in production until 1993. Design The Master series featured several improvements on preceding BBC Micro models. The systems had RAM as standard, alleviating the shortage of available RAM which had amongst other things discouraged use of the best graphics modes in the original design. The Master 128 and its variants had two cartridge slots mounted behind the new numerical keypad, these employing sockets that provided a superset of the Acorn Electron Plus 1 cartridge interface capabilities, supporting the use of physically compatible Electron cartridges, but also supporting enhanced electrical characteristics for some of the cartridge connector pins. Rather than the MOS Technology 6502 microprocessor used by the Model B it ran on the slightly improved 65C12. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleprompter
A teleprompter, also known as an autocue, is a display device that prompts the person speaking with an electronic visual text of a speech or script. Using a teleprompter is similar to using cue cards. The screen is in front of, and usually below, the lens of a professional video camera, and the words on the screen are reflected to the eyes of the presenter using a sheet of clear glass or other beam splitter, so that they are read by looking directly at the lens position, but are not imaged by the lens. Light from the performer passes through the front side of the glass into the lens, while a shroud surrounding the lens and the back side of the glass prevents unwanted light from entering the lens. Mechanically this works in a very similar way to the Pepper's ghost illusion from classic theatre: an image viewable from one angle but not another. Because the speaker can look straight at the lens while reading the script, the teleprompter creates the illusion that the speaker ha ...

Autocue
Autocue is a UK-based manufacturer of teleprompter systems. The company was founded in 1955 and licensed its first on-camera teleprompter, based on a patent by Jess Oppenheimer, in 1962. Its products are used by journalists, presenters, politicians and video production staff in almost every country in the world. In Dutch, "autocue" became a genericized trademark as there is no Dutch word for teleprompter. History of Autocue and teleprompting Prompting begins on paper Prompting began with Jess Oppenheimer, a writer, producer and director on the TV show ''I Love Lucy'' in the early 1950s. To solve the problem of the actors forgetting their lines, he developed the teleprompter system. Oppenheimer took out a patent on the system. He licensed the patent to the teleprompting company Autocue in 1955. Meanwhile, a separate entity, QTV, was established in the US. Both companies started by renting teleprompting equipment to studios and these were the first "on-camera" teleprompters in ...

BBC Micro
The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by Acorn Computers in the 1980s for the BBC Computer Literacy Project. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series, '' The Computer Programme'', featuring Chris Serle learning to use the machine, was broadcast on BBC2. After the Literacy Project's call for bids for a computer to accompany the TV programmes and literature, Acorn won the contract with the ''Proton'', a successor of its Atom computer prototyped at short notice. Renamed the BBC Micro, the system was adopted by most schools in the United Kingdom, changing Acorn's fortunes. It was also successful as a home computer in the UK, despite its high cost. Acorn later employed the machine to simulate and develop the ARM architecture. While nine mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn Eurocard System
The Acorn System was a series of modular microcomputer systems based on rack-mounted Eurocards developed by Acorn Computers from 1979 to 1982, aimed primarily at industrial and laboratory use, but also home enthusiasts. The experience gained in developing this modular system strongly influenced the design of Acorn's first all-in-one home computer, the Acorn Atom, released in March 1980; and also much of the circuitry in its successor, the BBC Micro, first shown in late 1981. Acorn's final rack-based machine was the System 5, released in late 1982. The Eurocard business was then sold on to one of its principal resellers, Control Universal Ltd, which continued to develop various cards for industrial use based on the Acorn-standard bus during the 1980s, but ultimately went into receivership in 1989. Eurocards Placing the two Eurocards from the original Acorn Microcomputer onto a backplane made the system straightforward to expand in a modular way. The original I/O card, minus i ...

Acorn Atom
The Acorn Atom is a home computer made by Acorn Computers Ltd from 1980 to 1982, when it was replaced by the BBC Micro. The Micro began life as an upgrade to the Atom, originally known as the Proton. The Atom was a progression of the MOS Technology 6502-based machines that the company had been making from 1979. The Atom was a cut-down Acorn System 3 without a disk drive but with an integral keyboard and cassette tape interface, sold in either kit or complete form. In 1980 it was priced between £120 in kit form, £170 () ready assembled, to over £200 for the fully expanded version with 12 KB of RAM and the floating-point extension ROM. Hardware The minimum Atom had 2 KB of RAM and 8 KB of ROM, with the maximum specification machine having 12 KB of each. An additional floating-point ROM was also available. The 2 KB of RAM was divided between 1 KB of Block Zero RAM (including the 256 bytes of "zero page") and 512 bytes for the screen (text ...
