Eniac

Babbage's big mistake was being born in an age which had the basic knowledge to design such a machine, but no technology with which to build it. LJISD

This is a short summary of what eniac is. ENIAC was the world's first general purpose, electronic, digital computer. "General purpose" means that ENIAC could be reconfigured to solve a variety of problems; "electronic" means ENIAC used electronic devices (i.e., vacuum tubes instead of mechanical methods like the relay switches that were used on most previous computers) for the actual computations; and "digital" means that ENIAC performed computations in discrete steps, unlike the analog computers prevalent at that time. ENIAC is the acronym for Electronic Numerical Integrator and Computer.

Eniac is short for Electronic Numerical Integrator and Computer. The first one was made by time during world war2.It is an acronym for Electronic Numerical Integrator and Computer, as it was the first operational electronic digital computer in the U.S. It was developed by the Army Ordnance. It was used as World War II ballistic firing tables. The ENIAC, weighing 30 tons, using 200 kilowatts of electric power and consisting of 18,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductor, was completed in 1945. It was heavy, as a matter of fact according to calculations, cosmic-ray studies, thermal ignition, random-number studies, wind-tunnel design, and other scientific uses. The ENIAC soon became obsolete as the need arose for faster computing speeds. Eniac’s is one of the host heaviest computers more than With the advent of everyday use of elaborate calculations, speed has become paramount to such a high degree that there is no machine on the market today capable of satisfying the full demand of modern computational methods. The ENIAC I In 1946, John Mauchly and John Presper Eckert developed the ENIAC I (Electrical Numerical Integrator and Calculator). The American military sponsored their research; the army needed a computer for calculating artillery-firing tables, the settings used for different weapons under varied conditions for target accuracy. The Ballistics Research Laboratory, or BRL, the branch of the military responsible for calculating the tables, heard about John Mauchly's research at the University of Pennsylvania's Moore School of Electrical Engineering. John Maulchy had previously created several calculating machines, some with small electric motors inside. He had begun designing (1942) a better calculating machine based on the work of John Atanasoff that would use vacuum tubes to speed up calculations. Scholars argue about its claims as the world's first all electronic computer and the courts have ruled otherwise, but when the University of Pennsylvania's "mathematical brain" was made public in 1946 it was an incredible breakthrough that could compute mathematical problems with breathtaking speed. ENIAC stands for Electronic Numerical Integrator and Computer. It was a secret World War II military project carried out by John Mauchly, a 32-year-old professor at Penn's Moore School of Electrical Engineering and John Presper Eckert Jr., a 24-year-old genius inventor and lab assistant. The challenge was to speed up the tedious mathematical calculations needed to produce artillery firing tables for the Army. ENIAC was not completed until after the war but it performed until 1955 at Aberdeen, Md. ENIAC was enormous. It contained 17,500 vacuum tubes, linked by 500,000 soldered connections. It filled a 50-foot long basement room and weighed 30 tons. Today, a single microchip, no bigger than a fingernail, can do more than those 30 tons of hardware. About 10 percent of the historic computer lives on in the same basement room where it was created. ENIAC's 50th anniversary was celebrated in 1996 with a visit by Vice President Al Gore. What was left of the old computer was fired up one last time. ENIAC is electrical engineering school at 33rd and Walnut. generally closed but special arrangement can be made to see it by contacting the University's .
I asked a friend what was eniac and she told me “Eniac was way we connected in World War 2, it was also used so that we could be connected with other people during world war 2.”So I searched it the first answer was right but as studies shows that in world war 2 not all people connected with other people.
