Electric 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 U.S. Census, 1890, 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 "supercomputer, 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 U.S. Census, 1880, 1880 census had taken eight years to process. Since the U.S. Constitution mandates a census every ten years to apportion both United States congressional apportionment, congressional representatives and direct taxes among the U.S. states, states, a combination of larger staff and faster-recording systems was required.

Jacquard Loom
The Jacquard machine () is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving innovations, as Jacquard shed (weaving), shedding made possible the automatic production of unlimited varieties of complex pattern weaving. The term "Jacquard" is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Business Machines
International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American Multinational corporation, multinational technology company headquartered in Armonk, New York, and present in over 175 countries. It is a publicly traded company and one of the 30 companies in the Dow Jones Industrial Average. IBM is the largest industrial research organization in the world, with 19 research facilities across a dozen countries; for 29 consecutive years, from 1993 to 2021, it held the record for most annual U.S. patents generated by a business. IBM was founded in 1911 as the Computing-Tabulating-Recording Company (CTR), a holding company of manufacturers of record-keeping and measuring systems. It was renamed "International Business Machines" in 1924 and soon became the leading manufacturer of Tabulating machine, punch-card tabulating systems. During the 1960s and 1970s, the IBM mainframe, exemplified by the IBM System/360, System/360 and its successors, wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fredrik Rosing Bull
Fredrik Rosing Bull (; 25 December 1882 – 7 June 1925) was a Norwegian scientist, information technology pioneer, known for his work on improved punched card machines. Bull was born in Kristiania (Oslo, Norway). In 1907, he finished his studies in civil engineering at the . In 1916, he was hired as a technical inspector for the insurance company Storebrand, where he developed an interest for punched card technology and began developing one of his own. In 1919, he obtained a patent for his machine, and in 1921 he prepared a team that took over the implementation of the machine at Storebrand. This team provided several new ideas for improving the Bull machine, rendering it superior to Herman Hollerith's device, the precursor to the IBM punched card machine, in use at that time. Bull continued to develop his ideas and improve the machine, which became a success throughout Europe. He was diagnosed with cancer in 1924 and died in 1925 at the age of 42. His patents were later sold in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powers Accounting Machine
The Powers Accounting Machine was an information processing device developed in the early 20th century for the U.S. Census Bureau. It was then produced and marketed by the Powers Accounting Machine Company, an information technology company founded by the machine's developer. The company thrived in the early 20th century as a producer of tabulating machines. It was a predecessor to the Unisys corporation. Development Census Bureau In 1890, the government began leasing tabulating machines from Herman Hollerith's Tabulating Machine Company, to more efficiently, expansively, and accurately produce the national census. In 1900, Hollerith raised the lease pricing. This led the newly formed U.S. Census Bureau to seek other suppliers under its new director, Simon North, in 1903. North returned most of Hollerith's machines, and the Census Bureau began using Charles F. Pidgin's tabulators. These machines proved too slow, so the Bureau undertook to develop its own machine for the 1910 ce ... [...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; it was subsequently known as IBM. In 1911, the financier and noted trust organizer Charles R. Flint, called the "Father of Trusts", 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 the International Business Machines Corporation (IBM) in 1924. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consolidation (business)
In business, consolidation or amalgamation is the merger and acquisition of many smaller companies into a few much larger ones. In the context of financial accounting, ''consolidation'' refers to the aggregation of financial statements of a group company as consolidated financial statements. The taxation term of consolidation refers to the treatment of a corporate group, group of companies and other entities as one entity for tax purposes. Under the Halsbury's Laws of England, ''amalgamation'' is defined as "a blending together of two or more undertakings into one undertaking, the shareholders of each blending company, becoming, substantially, the shareholders of the blended undertakings. There may be amalgamations, either by transfer of two or more undertakings to a new company or the transfer of one or more companies to an existing company". Overview Consolidation is the practice, in business, of legally combining two or more organizations into a single new one. Upon consolidati ...

Plugboard
A plugboard or control panel (the term used depends on the application area) is an array of jack (connector), jacks or sockets (often called hubs) into which patch cords can be inserted to complete an electrical circuit. Control panels are sometimes used to direct the operation of unit record equipment, :Cryptographic hardware, cipher machines, and History of computing hardware#Digital computation, early computers. The array of holes is often contained in a flat removable panel that can be inserted into a machine and pressed against an array of contacts. This allows the machine to be quickly switched between different applications. The contacts on the machine are hard wired to the various devices that comprise the machine, such as relays, counters, inputs from each card reader column, outputs to a card punch column or printer position, and so on. The wiring on a plugboard connects these devices to perform a specific function, say reading cards and summing up the numbers punched ...
