| How First-Generation Computers was powered? | They were powered by thousands of vacuum tubes. |
| What are the problems with vacuum tubes? | The vacuum tubes required constant replacement required a lot of electricity, and generated a lot of heat. |
| How did the First-Generation computer calculate? | First-generation computers could solve only one problem at a time since they needed to be physically rewired with cables to be reprogrammed. |
| How was the calculation performed? | It took a few days (sometimes even weeks) to calculate and a few more days to check before the computer could be used. |
| Two of the most significant examples of first-generation computers were .. | ENIAC and UNIVAC. |
| Which input and output devices did the FG computer use? | Usually, paper punch cards and paper tape were used for input, and output was printed on paper. |
| For which ENIAC was used and II. world war? | ENIAC was used to calculate artillery tables for the U.S. military. |
| How is ENIAC computers evaluated? | Instead of the 40 hours required for a person to compute, ENIAC could complete the same calculations in less than two minutes. |
| When and for whom was UNIVAC realized? | 1951. initially built for the U.S. Census Bureau and was used to analyze votes in the 1952 U.S. presidential election. |
| What is interesting about UNIVAC? | Correct prediction of an Eisenhower victory only 45 minutes after the polls closed was not publicly aired because the results were not trusted. |
