The ENIAC - Pooja Sharma
World War II • Series of inventions • Radar • Jet Engines • Nuclear Weapons and • COMPUTERS!!
ENIAC - History • Electronic Numerical Integrator And Computer • Initiated on June 5, 1943 by the Ordnance Department • Key Supervisors • Professor Brainard • Dr. Eckert • Dr. Mauchly
ENIAC - Components • It filled an entire room • Weighed thirty tons • Consumed two hundred kilowatts of power • 19,000 Vacuum tubes for computer circuit • arranged in a "U" shape, with three panels on wheels • IBM card reader and card punch were used for input and output
ENIAC – Features • Eight basic circuit components • Accumulator • Initiator master programmer • Multiplier • Divider/Square-root • Gate • Buffer • Function tables.
ENIAC – Functions • Solve the atomic energy problems for the Manhattan Project • Problems for weather prediction • Cosmic ray studies in astronomy • Random number studies • Designing wind tunnels.
ENIAC - Impact on Speed • Ballistic trajectories can take someone with a hand calculator twenty hours to compute • Bush differential analyzer reduced this time down to fifteen minutes • ENIAC could do it in Thirty Seconds!!
Bigger is not always better • High reliance on vacuum tubes • Took a number of days to fix • Increased downtime
Nothing Lasts Forever • Ten years after its dedication – ENIAC was shutdown • Could not compete against less expensive machines • Parts of the machine can be seen on display in various museums throughout the world
