Ferranti MRT
The Ferranti Market Research Terminal (MRT) was, arguably, the world’s first application-specific handheld computer. It was designed specifically for the market research sector as a means to augment the regular clipboard schemes that, at the time, were common-place, in Social research, social and market research. Despite having an appearance of a calculator built into a clipboard, the reality was that the unit contained a sophisticated form of programmable data-logger that, in response to an interviewer reading questions to the interviewee, had answers digitally recorded (for later uploading and analysis) via pressing appropriate keys on the unit. The unit contained a bespoke operating system to support field based market research. The Ferranti Market Research Terminal (MRT) is also of historical significance to the computing industry since it marked the last original computer design from Ferranti, a long established business (started 1882) that had risen to fame through a co ...

Tandy Pocket Computer
The Tandy Pocket Computer or TRS-80 Pocket Computer is a line of pocket computers sold by Tandy Corporation under the Tandy or RadioShack, Radio Shack TRS-80 brands. Although named after the TRS-80 line of computers, they were not compatible with any TRS-80 desktop computer and did not use the Zilog Z80, Z80 CPU. Models in the Pocket Computer line were actually Badge engineering, rebadged Sharp Corporation, Sharp and Casio devices with different model names. They were given designations from PC-1 to PC-8. The PC-1, PC-2, PC-3 and PC-8 were designed by Sharp; while the PC-4, PC-5, PC-6 and PC-7 were designed by Casio. History, lineage and nomenclature Tandy introduced its first Pocket Computer in 1980 as an experiment; ''BYTE'' stated that "neither Tandy nor any of the other pocket-computer makers really know if there is a meaningful market for this machine". The magazine said that the vendors expected that businessmen would use them with a modem to communicate with larger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computers Designed In The United Kingdom
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of com ...

Ferranti Computers
Ferranti International PLC or simply Ferranti was a UK-based electrical engineering and equipment firm that operated for over a century, from 1885 until its bankruptcy in 1993. At its peak, Ferranti was a significant player in power grid systems, defense electronics, and computing, and was once a constituent of the FTSE 100 Index. The company had an extensive presence in the defense sector, manufacturing advanced cockpit displays, radar transmitters, inertial navigation systems, and avionics for military aircraft, including the Tornado fighter jet. It was a pioneer in computer technology, launching the Ferranti Mark 1 in 1951, one of the world's first commercially available computers. Ferranti's global footprint extended beyond the UK, with factories and branch plants in Australia, Canada, Singapore, Germany, and the United States. The company had a strong presence in Edinburgh, with numerous branch-plants as well as an aviation facility. Despite its eventual collapse, some p ...

Mobile Computing
Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage and allow for transmission of data, which can include voice and video transmissions. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications. Main principles * Portability: Devices/nodes connected within the mobile computing system should facilitate mobility. These devices may have limited device capabilities and limited power supply but should have a sufficient processing capability and physical portability to operate in a movable environment. * Connectivity: This defines the quality of service (QoS) of the network connectivity ...

Clipboard
A clipboard is a thin, rigid writing board with a clip at the top for holding paper in place. A clipboard is typically used to support paper with one hand while writing on it with the other, especially when other writing surfaces are not available. The earliest forms were patented in 1870–1871 and referred to as board clips. Another early version of the clipboard, known as the "memorandum file", was invented by American inventor George Henry Hohnsbeen in 1921, for which he was granted . Related to the clipboard is the Shannon Arch File, which was developed around 1877. Variations Clipboards can be constructed from a variety of material, including but not limited to, hardboard, aluminum, PVC, polypropylene, High Impact Polystyrene, and Foamex. Clipboards generally come in two different designs—single or folding. Single clipboards are the more traditional type and consist of a single piece of rigid material and some sort of fixing mechanism along the top. Folding clipboar ...

Opinion Polls
An opinion poll, often simply referred to as a survey or a poll, is a human research survey of public opinion from a particular sample. Opinion polls are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals. A person who conducts polls is referred to as a pollster. History The first known example of an opinion poll was a tally of voter preferences reported by the ''Raleigh Star and North Carolina State Gazette'' and the ''Wilmington American Watchman and Delaware Advertiser'' prior to the 1824 presidential election, showing Andrew Jackson leading John Quincy Adams by 335 votes to 169 in the contest for the United States presidency. Since Jackson won the popular vote in that state and the national popular vote, such straw votes gradually became more popular, but they remained local, usually citywide phenomena. In 1916, ''The Literary Digest'' embarked on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Market Research
Market research is an organized effort to gather information about target markets and customers. It involves understanding who they are and what they need. It is an important component of business strategy and a major factor in maintaining competitiveness. Market research helps to identify and analyze the needs of the market, the market size and the competition. Its techniques encompass both qualitative techniques such as focus groups, in-depth interviews, and ethnography, as well as quantitative techniques such as customer surveys, and analysis of secondary data. It includes social and opinion research, and is the systematic gathering and interpretation of information about individuals or organizations using statistical and analytical methods and techniques of the applied social sciences to gain insight or support decision making. Market research, marketing research, and marketing are a sequence of business activities; sometimes these are handled informally. The field of ...

History Of Computing
The history of computing is longer than the history of computing hardware and modern computing technology and includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables. Concrete devices Digital computing is intimately tied to the representation of number A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can ...s. But long before abstractions like ''the number'' arose, there were mathematical concepts to serve the purposes of civilization. These concepts are implicit in concrete practices such as: *''Bijection, One-to-one correspondence'', a rule to counting, count ''how many'' items, e.g. on a tally stick, eventually abstracted into ''numbers''. *''Comparison to a standard'', a method for assuming ''reproducibility'' in a measure ...

Atlas (computer)
The Atlas 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's 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 and Plessey. Two other Atlas machines were built: one for BP and the University of London, and one for the Atlas Computer Laboratory at Chilton near Oxford. A derivative system was built by Ferranti for the University of Cambridge. Called the Titan, or Atlas 2, it had a different memory organisation and ran a time-sharing operating system developed by Camb ...

NSFNET
The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) from 1985 to 1995 to promote advanced research and education networking in the United States. The program created several nationwide backbone computer networks in support of these initiatives. It was created to link researchers to the NSF-funded supercomputing centers. Later, with additional public funding and also with private industry partnerships, the network developed into a major part of the Internet backbone. The National Science Foundation permitted only government agencies and universities to use the network until 1989 when the first commercial Internet service provider emerged. By 1991, the NSF removed access restrictions and the commercial ISP business grew rapidly. History Following the deployment of the Computer Science Network (CSNET), a network that provided Internet services to academic computer science departments, ...
