The ENIAC is created
The Electronic Numerical Integrator and Computer, the
ENIAC, was constructed between 1943 and 1946 at the University of Pennsylvania.
It was the most powerful computer up to that point but was the largest
as well, weighing over 30 tons. Additionally it required that almost
50 vacuum tubes be replaced everyday. While operating the ENIAC used almost
150 kilowatts of power, which is equivalent to what many small towns used
at that time. The ENIAC was important because of its power, but its
many drawbacks made it unrealistic for common use. One of these drawbacks
was that it had no memory. The same researchers who created the ENIAC then
set out to create a similar computer that allowed for the storing of programs.
