In 1930 the first analog computer was built by American named Vannevar
Bush. This device was used in World War II to help aim guns.
Many technical developments of electronic digital computers took place
in the 1940s and 1950s. Mark I, the name given to the first digital computer,
was completed in 1944. The man responsible for this invention was Professor
Howard Aiken. This was the first machine that could figure out long lists of
mathematical problems at a very fast rate.
In 1946 two engineers at the University of Pennsilvania, J. Eckert and
J. Maushly, built their digital computer with vacuum tubes. They named
their new invention ENIAC (the Electronic Numerical Integrator and Calculator).
Another important achievement in developing computers came in 1947,
when John von Neumann developed the idea of keeping instructions for
the computer inside the computer’s memory. The contribution of John von
Neumann was particularly significant. As contrasted with Babbage’s analytical engine, which was designed to store only data, von N eum ann’s machine,
called the Electronic Discrete Variable Computer, or EDVAC, was able to
store both data and instructions. He also contributed to the idea of storing
data and instructions in a binary code that uses only ones and zeros. This
simplified computer design. Thus computers use two conditions, high voltage and low voltage, to translate the symbols by which we communicate into
unique combinations of electrical pulses. We refer to these combinations as
codes.
N eumann’s stored program computer as well as other machines of that
time were made possible by the invention of the vacuum tube that could control and amplify electronic signals. Early computers, using vacuum tubes,
could perform computations in thousandths of seconds, called milliseconds,
instead of seconds required by mechanical devices.
