John Adam Presper Eckert Jr. (April 9, 1919 – June 3, 1995) was an American electrical engineer and computer pioneer.With John Mauchly, he designed the first general-purpose electronic digital computer (), presented the first course in computing topics (the Moore School Lectures), founded the Eckert–Mauchly Computer Corporation, and designed the first commercial computer in the U.S., the ...
John Presper Eckert (ur. 9 kwietnia 1919 w Filadelfii, zm. 3 czerwca 1995) – inżynier amerykański. Uzyskał tytuł bachelor of science na Uniwersytecie Pensylwanii w 1941 roku. Tytuł Master of Science uzystał na Moore School of Electrical Engineering przy Uniwersytecie Pensylwanii.
ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States. American physicist John Mauchly, American engineer J. Presper Eckert, Jr., and their colleagues at the Moore School of Electrical Engineering at the University of Pennsylvania led a government-funded project to build an ...
John Mauchly was a professor at Urisinus College when he enrolled in the course. Later, because of his outstanding performance at ESMWT, he was hired at Penn to replace professors called away to active duty. It was during this time that Mauchly met J. Presper Eckert, who was a graduate of Penn and hired to run the laboratory for the ESMWT course.
In computer programming, a subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed.
Other engineers, notably John W. Mauchly and J. Presper Eckert, contributed to this idea, which enabled digital computers to become much more flexible and powerful. Nevertheless, engineers in England built the first stored-program computer, the Manchester Mark I , shortly before the Americans built EDVAC , both operational in 1949.
Vacuum tubes were highly inefficient, required a great deal of space, and needed to be replaced often. Computers of the 1940s and 50s had 18,000 tubes in them and housing all these tubes and cooling the rooms from the heat produced by 18,000 tubes was not cheap.
Definición. Las ecuaciones que relacionan dimensionalmente el vatio con las unidades básicas del Sistema Internacional son: . En términos de la mecánica clásica: Cuando la velocidad de un objeto se mantiene constante a un metro por segundo con la oposición de una fuerza de un newton la tasa a la que se realiza el trabajo es un vatio.
When the world's first general-purpose, programmable, electronic computer, known as ENIAC, debuted in 1946, great fanfare was given to the men who created it, John Mauchly and J. Presper Eckert Jr ...
