Processed Data
Data processing is the collection and manipulation of digital data to produce meaningful information. Data processing is a form of ''information processing'', which is the modification (processing) of information in any manner detectable by an observer.Data processing is distinct from ''word processing'', which is manipulation of text specifically rather than data generally. Functions Data processing may involve various processes, including: * Validation – Ensuring that supplied data is correct and relevant. * Sorting – "arranging items in some sequence and/or in different sets." * Summarization (statistical) or (automatic) – reducing detailed data to its main points. * Aggregation – combining multiple pieces of data. * Analysis – the "collection, organization, analysis, interpretation and presentation of data." * Reporting – list detail or summary data or computed information. * Classification – separation of data into various ...

Data Collection
Data collection or data gathering is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical science, physical and social sciences, humanities, and business. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same. The goal for all data collection is to capture evidence that allows data analysis to lead to the formulation of credible answers to the questions that have been posed. Regardless of the field of or preference for defining data (Quantitative method, quantitative or Qualitative method, qualitative), accurate data collection is essential to maintain research integrity. The selection of appropriate data collection instruments (existing, modified, or newly developed) and delineated instructions for their correct use reduce the l ...

Human Computer
The term "computer", in use from the early 17th century (the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic calculators became available. Alan Turing described the "human computer" as someone who is "supposed to be following fixed rules; he has no authority to deviate from them in any detail." Teams of people, often women from the late nineteenth century onwards, were used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel. The same calculations were frequently performed independently by separate teams to check the correctness of the results. Since the end of the 20th century, the term "human computer" has also been applied to individuals with prodigious powers of mental arithmetic, also known as mental calculators. Origins in sciences Astronomers in Renaissance times used that term about as often as they called themselves " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information System
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, Information Processing and Management, store, and information distribution, distribute information. From a sociotechnical perspective, information systems comprise four components: task, people, structure (or roles), and technology. Information systems can be defined as an integration of components for collection, storage and data processing, processing of data, comprising digital products that process data to facilitate decision making and the data being used to provide information and contribute to knowledge. A computer information system is a system, which consists of people and computers that process or interpret information. The term is also sometimes used to simply refer to a computer system with software installed. "Information systems" is also an academic field of study about systems with a specific reference to information and the complementary networks of computer ...

Data Processing Management Association
The Association of Information Technology Professionals (AITP) is a professional association that focuses on information technology education for business professionals. The group is a non-profit US-oriented group, but its activities are performed by 62 local chapters organized on a geographic basis, and 286 student chapters at colleges and universities. History The group was first organized in Chicago, United States, in 1949 as the National Machine Accountants Association (NMAA). The State of Illinois granted the NMAA a charter on December 26, 1951. It soon had over 20 chapters. Harvey W. Protzel, systems manager for Protzel's Company, was elected the first International President at the 1952 First Annual Convention in Minneapolis. In 1962, it adopted the more inclusive name, Data Processing Management Association (DPMA), and in 1996, the present name. The Association began its certification program with the Certificate in Data Processing (CDP) professional examination, first ...

UNIVAC I
The UNIVAC I (Universal Automatic Computer I) was the first general-purpose electronic digital computer design for business application produced in the United States. It was designed principally by J. Presper Eckert and John Mauchly, the inventors of the ENIAC. Design work was started by their company, Eckert–Mauchly Computer Corporation (EMCC), and was completed after the company had been acquired by Remington Rand (which later became part of Sperry Corporation, Sperry, now Unisys). In the years before successor models of the UNIVAC I appeared, the machine was simply known as "the UNIVAC".Johnson, L.R., "Coming to grips with Univac," IEEE Annals of the History of Computing, vol. 28, no. 2, pp. 32, 42, April–June 2006. The first UNIVAC was accepted by the United States Census Bureau on March 31, 1951, and was dedicated on June 14 that year. The fifth machine (built for the United States Atomic Energy Commission, U.S. Atomic Energy Commission) was used by CBS to predict the ...

1950 United States Census
The 1950 United States census, conducted by the Census Bureau, determined the resident population of the United States to be 151,325,798, an increase of 14.5 percent over the 131,669,275 persons enumerated during the 1940 census. This was the first census in which: * More than one state recorded a population of over 10 million * Every state and territory recorded a population of over 100,000 * All 100 largest cities recorded populations of over 100,000 On April 1, 2022, the National Archives and Records Administration released scanned census enumeration sheets to the general public, in accordance with the 72 year rule. It is most recent census to have full public availability. Census questions The 1950 census collected the following information from all respondents: * address * whether house is on a farm * name * relationship to head of household * race * sex * age * marital status * birthplace * if foreign born, whether naturalized * employment status * hours worked in w ...

Electronic Computers
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 compute ...

Electronic Data Processing
Electronic data processing (EDP) or business information processing can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and customer master files, booking and ticketing transactions to an airline's reservation system, billing for utility services. The modifier "electronic" or "automatic" was used with "data processing" (DP), especially c. 1960, to distinguish human clerical data processing from that done by computer. History Herman Hollerith then at the U.S. Census Bureau devised a tabulating system that included cards (Punched card, Hollerith card, later Punched card), a punch for holes in them representing data, a tabulator and a sorter. The system was tested in computing mortality statistics for the city of Baltimore. In the first commercial electronic data p ...

Punched Card
A punched card (also punch card or punched-card) is a stiff paper-based medium used to store digital information via the presence or absence of holes in predefined positions. Developed over the 18th to 20th centuries, punched cards were widely used for data processing, the control of automated machines, and computing. Early applications included controlling weaving looms and recording census data. Punched cards were widely used in the 20th century, where unit record equipment, unit record machines, organized into data processing systems, used punched cards for Input (computer science), data input, data output, and data storage. The IBM 12-row/80-column punched card format came to dominate the industry. Many early digital computers used punched cards as the primary medium for input of both computer programs and Data (computing), data. Punched cards were used for decades before being replaced by magnetic storage and terminals. Their influence persists in cultural references, sta ...

Herman Hollerith
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century. Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing. Biography Herman Hollerith was born in Buffalo, New York, in 1860, where he also spent his early childhood. His paren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Record Equipment
Starting at the end of the nineteenth century, well before the advent of electronic computers, data processing was performed using Electromechanics, electromechanical machines collectively referred to as unit record equipment, electric accounting machines (EAM) or tabulating machines. Unit record machines came to be as ubiquitous in industry and government in the first two-thirds of the twentieth century as computers became in the last third. They allowed large volume, sophisticated data-processing tasks to be accomplished before electronic computers were invented and while they were still in their infancy. This data processing was accomplished by processing punched cards through various unit record machines in a carefully choreographed progression. This progression, or flow, from machine to machine was often planned and documented with detailed flowcharts that used standardized symbols for documents and the various machine functions. All but the earliest machines had high-speed me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
