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.

Unit Record Equipment
Starting at the end of the nineteenth century, well before the advent of electronic computers, data processing was performed using 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 mechanical feeders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punched Card
A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and 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. While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still used punched cards to record votes. They also had a significant cultural impact.

Tabulating Machine
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry. The term " Super Computing" was used by the ''New York World'' newspaper in 1931 to refer to a large custom-built tabulator that IBM made for Columbia University. 1890 census The 1880 census had taken eight years to process. Since the U.S. Constitution mandates a census every ten years to apportion both congressional representatives and direct taxes among the states, a combination of larger staff and faster-recording systems was required. In the late 1880s Herman Hollerith, inspired by conductors using holes punched in different positions on a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computing-Tabulating-Recording Company
The Computing-Tabulating-Recording Company (CTR) was a holding company of manufacturers of record-keeping and measuring systems subsequently known as IBM. In 1911, financier and noted trust organizer, "Father of Trusts", Charles R. Flint amalgamated (via stock acquisition) four companies: Bundy Manufacturing Company, International Time Recording Company, the Tabulating Machine Company, and the Computing Scale Company of America; creating a fifth company – the Computing-Tabulating-Recording Company. CTR was initially located in Endicott, New York The amalgamated companies had 1,300 employees and manufactured a wide range of products, including employee time-keeping systems, weighing scales, automatic meat slicers, and punched card equipment. CTR was renamed as the International Business Machines Corporation (IBM) in 1924. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Census, 1890
The United States census of 1890 was taken beginning June 2, 1890, but most of the 1890 census materials were destroyed in 1921 when a building caught fire and in the subsequent disposal of the remaining damaged records. It determined the resident population of the United States to be 62,979,766an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census. The data reported that the distribution of the population had resulted in the disappearance of the American frontier. This was the first census in which a majority of states recorded populations of over one million, as well as the first in which multiple citiesNew York as of 1880, Chicago, and Philadelphiarecorded populations of over one million. The census also saw Chicago rise in rank to the nation's second most populous city, a position it would hold until Los Angeles (then 57th) would supplant it in 1990. This was the first U.S. census to use machines to tabulate the collected data. Census quest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Data Processing
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. The term "Data Processing", or "DP" has also been used to refer to a department within an organization responsible for the operation of data processing programs. Data processing 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, ...
