This was not a dream of science fiction, but a representation of ENIAC (Electronic Numerical Integrator Analyzer and Computer), the gigantic machine credited with starting the modern computer age. ENIAC, with its 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, and 6,000 manual switches, was a monument of engineering -- and an energy hog.
ENIAC, the mammoth machine credited with helping to start the computer age, fueled the public's imagination about how science and computers could revolutionize the world. Little did they realize how different that early computer was from the ones that would be built a mere fifty years later.ENIAC stands for Electronic Numerical Integrator and Computer. John Mauchly and J. Presper Eckert built the machine at the University of Pennsylvania at the behest of the U.S. military.NIAC, the mammoth machine credited with helping to start the computer age, fueled the public's imagination about how science and computers could revolutionize the world.
