  4. 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

  5. ENIAC – Features • Eight basic circuit components • Accumulator • Initiator master programmer • Multiplier • Divider/Square-root • Gate • Buffer • Function tables.

  6. 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.

  7. 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!!

  8. Bigger is not always better • High reliance on vacuum tubes • Took a number of days to fix • Increased downtime

  9. 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
