The ENIAC computer system was a leap forward in computer technology. It was the first real industrial use of computers. It was 1,000 times faster than computers of its time and allowed many different operation at the same time. It was located in Philadelphia and required so much electricity that the city lights dimmed when it was in use. The size of the computer took up the space of a small house. The vacuum tube technology made it heat up quickly. It was programmed with cards, switches, and plug boards. The use of the machine offered many operations fast and opened up the possibility of computers to industry.
