There's been a controversy in the computing world when discussing what was the very first computer invented.
For years, the accepted pioneer with the digital age was the ENIAC, short for Electronic Numerical Integrator And Computer, perhaps because tale became media frenzy associated with growth was one worthy for tabloids and tv.
As World War II was creating any close, the Army had run short of mathematicians and were willing to recruit women. Six women were accepted how to start an invention idea work on "Project PX" at the University of Pennsylvania's Moore School of Electrical Engineering, under John Mauchly and L. Presper Eckert. The women's job would have program firing tables and ballistic trajectories using ENIAC. Their work laid the groundwork for selection. The completed machine was unveiled on Feb. 14, 1946 at the University of Pennsylvania. The military had funded diet plans almost $500,000. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. It is widely considered to emerge as the first computer invented, considering its highly functional status from the late 1950s.
However, its "first" status was challenged in court when Rand Corp. bought the ENIAC patent and started charging royalties. Honeywell Inc. refused to pay and challenged the patent in 1968. It was learned that Mauchly, on the list of leaders of the Project PX in the University of Pennsylvania, had seen an early prototype of a machine being built in the Iowa State College called the Atanasoff-Berry Computer.
Professor John Vincent Atanasoff and graduate student Cliff Berry began development along at the ABC in 1937 and it continued to be developed until 1942 at the Iowa State College (now Iowa State University). Eventually, it could solve equations containing 29 variables.
In 1973, You.S. Federal Judge Earl R. Larson released his decision that the ENIAC patent by Mauchly and Eckert was invalid along with the ABC was actually the first computer invented. However, the ABC was never fully functional, new invention so the most popular opinion to this day has the ENIAC as the first electronic computing device. The Smithsonian Institute's Museum of American History in Washington displays most of the things remains of the ENIAC, alongside bits of the ABC.
However, there's another twist to this tale. The easiest computer is an electronic digital device designed to adopt data, perform prescribed mathematical and logical operations and how to patent a product display the results. Germany's Konrad Zuse created what was basically the first programmable calculator in the mid-1930s in his parent's living room. Zuse's Z1 had 64-word memory and a clock speed of 1 Hz. Programming the the Z1 required the user to insert tape into a punch tape reader and then receive his results the punch tape dispenser - making it possibly the first computer invented.
