MARK-IV (Software)
Mark IV is a fourth-generation programming language that was created by Informatics, Inc. in the 1960s. It automated the reading of input files and conversion of the data inside to produce one or more reports and updated output files. At the time, this program was called a ''file management system'', though it was not what today is understood by that term (a file manager); rather, it was what today would be known as a report generator. It was used for roles similar to the COBOL programming language or PL/1, but was far easier to use and the instructions normally consisted of a single piece of paper that was converted to a few punch cards. Customers lauded the product for its time savings, often able to generate one-off reports in a matter of days when weeks or months would be needed with traditional tools. It is historically important as one of the first examples of commercial software that was sold by an independent vendor. It was also the first software product to break $10 ...

Subroutine
In computer programming, a function (also procedure, method, subroutine, routine, or subprogram) is a callable unit of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool. The primary purpose is to allow for the decomposition of a large and/or complicated problem into chunks that have relatively low cognitive load and to assign the chunks meaningful names (unless they are anonymous). Judicious application can reduce the cost of developing and maintaining software, while increasing its quality and reliability. Callable units are present at multiple levels of abstraction in the programming environment. For example, a programmer may write a function in source code that is compiled to machine code that implements similar semantics. There is a callable unit in the source code and an associated one in the machine code, but they are different kinds of callable units with different impl ...

Flowchart
A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows. This diagrammatic representation illustrates a solution model to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields. * ''Document flowcharts'', showing controls over a document-flow through a system * ''Data flowcharts'', showing controls over a data-flow in a system * ''System flowcharts'', showing controls at a physical or resource level * ''Program flowchart'', showing the controls in a program within a system Notice that every type of flowchart focuses on some kind of control, rather than on the particular flow itself. However, there are some different classifications. For example, Andrew Veronis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autoflow
Autoflow was an application program from Applied Data Research (ADR) for mainframe computers that reads assembly language programs and produces a flowchart of that code. It is historically notable as one of the first software applications to be offered for sale independent of the system it ran on, as well as the first to receive a software patent in the United States, and to be licensed to customers rather than sold. Autoflow was introduced in 1964 for the RCA 501. Originally intending to have RCA purchase it and give it to their customers, RCA thought its $25,000 price was too high and declined to buy it. ADR then approached 501 owners directly, becoming what is generally accepted to be the first commercial software vendor. The RCA market was small, so ADR ported it to the IBM 1401 and began sales into that much larger market in 1965. These early versions required the user to indicate the symbol for each chart entry using a numeric code entered as a comment in the code. This wa ...

Applied Data Research
Applied Data Research, Inc. (ADR), was a large software vendor from the 1960s until the mid-1980s. ADR is often described as "the first independent software vendor". Founded in 1959, ADR was originally a contract development company. ADR eventually built a series of its own products. ADR's widely used major packages included: Autoflow for automatic flowcharting, which is often cited as one of the first commercial software applications; Roscoe, a remote job submission environment; MetaCOBOL, an extensible macro processor for the COBOL language; and The Librarian, for source-code management. The company's original office was in a small office building along U.S. Route 206 in Princeton Township, New Jersey. Later during the 1960s, they were part of a data center located on Route 206 across from Princeton Airport. The center was destroyed by fire in 1969 when a light plane crashed into it on approach to the airport, but there were no serious injuries among either the pilot or ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Association For Computing Machinery
The Association for Computing Machinery (ACM) is a US-based international learned society for computing. It was founded in 1947 and is the world's largest scientific and educational computing society. The ACM is a non-profit professional membership group, reporting nearly 110,000 student and professional members . Its headquarters are in New York City. The ACM is an umbrella organization for academic and scholarly interests in computer science (informatics). Its motto is "Advancing Computing as a Science & Profession". History In 1947, a notice was sent to various people: On January 10, 1947, at the Symposium on Large-Scale Digital Calculating Machinery at the Harvard computation Laboratory, Professor Samuel H. Caldwell of Massachusetts Institute of Technology spoke of the need for an association of those interested in computing machinery, and of the need for communication between them. ..After making some inquiries during May and June, we believe there is ample interest to ...

Howard Hughes
Howard Robard Hughes Jr. (December 24, 1905 – April 5, 1976) was an American Aerospace engineering, aerospace engineer, business magnate, film producer, and investor. He was The World's Billionaires, one of the richest and most influential people in the world during his lifetime. He first became prominent as a film producer, and then as an important figure in the aviation industry. Later in life, he became known for his eccentric behavior and reclusive lifestyle—oddities that were caused in part by his worsening obsessive-compulsive disorder (OCD), chronic pain from a near-fatal plane crash, and increasing deafness. As a film tycoon, Hughes gained fame in Hollywood beginning in the late 1920s, when he produced big-budget and often controversial films such as ''The Racket (1928 film), The Racket'' (1928), ''Hell's Angels (film), Hell's Angels'' (1930), and ''Scarface (1932 film), Scarface'' (1932). He later acquired the RKO Pictures film studio in 1948, recognized then as one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hughes Tool Company
Hughes Tool Company was an American manufacturer of drill bits. Founded in 1908, it was merged into Baker Hughes Incorporated in 1987. History The company was established in December 1908 as Sharp-Hughes Tool Company when Howard R. Hughes Sr. patented a roller cutter bit that dramatically improved the rotary drilling process for oil drilling rigs. He partnered with longtime business associate Walter Benona Sharp to manufacture and market the bit. Following her husband's death in 1912, Sharp's widow Estelle Sharp sold her 50% share in the company to Howard Hughes Sr. in 1914. The company was renamed Hughes Tool Company on February 3, 1915. After Hughes Sr. died of a heart attack in 1924, his son Howard Jr. inherited the majority interest in the company, and then convinced his relatives to sell their shares to him as well. Legally emancipated at the age of 18, Howard began using the profits from Hughes Tool to fund his other ventures. Toolco paid Hughes an annual salary of ...
