Each Accumulator could do 5000 additions or subtractions per second and there were 20 Accumulators that could potentially all run simultaneously if the problem could be setup with enough parallelism (which was difficult to do and thus rare, even when it could be done it was impossible to sustain for long).
The theoretical ideal case speed (with full parallelism) was 5000 * 20 = 100,000 additions or subtractions per second.
The first computer was the ENIAC, completed in 1946. It could do simple mathematical equations such as add and subtract.
It could do 5000 additions/subtractions per second in each accumulator. It had 20 accumulators and could run several at the same time.
to perform mathematical calculations at a very fast speed.it could do 5000 additions and 360 multiplications in just 1 second.
what was eniac?
The ENIAC was built by the U.S. Army.
no, ENIAC was fully electronic.
The ENIAC computer was finished in November, 1945.
No. ENIAC was invented long before Microsoft was founded.
No. the ENIAC had a printer instead. http://en.wikipedia.org/wiki/ENIAC
The ENIAC used 160 kilowatts (160,000 watts).
The Eniac had 17,468 vacuum tubes. The Eniac (Electronic Numerical Integrator And Computer) is recognized as the first electronic general-purpose computer.
The ENIAC computer was named so because of the operations the computer were capable of. ENIAC stands for "Electronic Numerical Integrator And Computer".
Here is a really interesting site that is all about ENIAC > http://www.seas.upenn.edu/~museum/
ENIAC was built by the Moore School of Electrical Engineering; at the University of Pennsyvania in Philadelphia
berry had nothing to do with ENIAC
8.5 feet by 3 feet by 80 feet. For the complete information on the Eniac, go to the related links box below were I posted the wikipedia Eniac article.
The edvac came after the eniac (its predecessor). The main difference was that with the eniac if you wanted to complete a certain process different vacuum tubes had to be tampered with, whereas with the edvac john von neumann and others realised that computers could be programmed which meant you didnt have to tamper with the hardware each time you wanted to complete a different a task.
ENIAC was one of the first computers, originally built by the US Army to calculate trajectories for artillery.
Babbage died long before ENIAC was even thought of! He had nothing to do with it.
ENIAC weighed more than 30 short tons or 6,000 pounds.
ENIAC are use in calculating ballistic firing tubes and also in designing atomic weapon
J. Presper Eckert and John W Mauchly
A computer. ENIAC stands for Electronic Numerical Integrator And Calculator.The ENIAC was the first digital computer in the modern sense of the word, built in 1942-1945 in USA.
