Mississauga, Canada (prHWY.com) October 10, 2012 - The debate on the first computer ever made may vary according to the perception of what constitutes a computer. For some, it is the ENIAC made in 1943, while for some it is the Altair launched by MITS in 1974. It is interesting to know that the term 'computer' was assigned to people's job which consisted of performing calculations on a continuous basis, like navigational tables, tide charts, and planetary positions for astronomical needs. Human errors, boredom and comparatively slow pace of working, led inventors to mechanize the entire process and eventually come up with machines that had brains - computers! Need for accurate and fast calculations led to the invention of tools like Napier's bones for logarithms, the slide rule, calculating clock, Pascal's Pascaline, and power-loom that used punched cards; which can be considered as the forefathers of today's computers.


Talking about the history and evolution of computers, will be incomplete without the mention of Charles Babbage, who is considered the 'Father of Computers'. He was making a steam-driven calculating machine, the size of a room, way back in 1822, which he called the 'Difference Engine'. This project, though heavily funded by the British government, could never see the light of the day. Yet, in pursuit of a better machine for more complex calculations, he came up with the 'Analytical Engine' that had parts parallel to the memory card and the central processing unit that our systems have today. Hollerith desk was later invented in the U.S. For the need to record the census in 1880, which used a combination of the earlier calculating tools that were invented.


In the 1940s there were attempts to make machines that served the purpose of computing numbers and problems, like the Z1 Computer in 1936. Then Konrad Zuse also wanted to make something that would be like a computer, hence was created electromechanical "Z machines," the Z3, in 1941, which was the first working machine, which featured binary arithmetic, including floating point arithmetic and a measure of programmability. Zuse also started the first computer start-up company, which was established in 1946.


The ABC or Atanasoff-Berry Computer in 1942, Harvard Mark I Computer in 1944 also contributed to the evolution of computers that we know them today. It was not before the ENIAC that the public got its first feel of computers.


ENIAC / Electronic Numerical Integrator And Computer

It was during World War II that the need for computing artillery firing tables for the United States Army's Ballistic Research Laboratory arose, which gave birth to the giant electronic brain - ENIAC. When the design and construction for this machine was financed by the United States Army, and the contract was signed on June 5, 1943; work progressed secretly in the University of Pennsylvania Moore School of Electrical Engineering, under the name 'Project PX'. Three years of dedicated work by John Mauchly, J. Presper Eckert and their team towards making this machine finally tasted success when it was announced to the public on February 14, 1946; which was formally accepted by the Army in July 1946. ENIAC was, however, shut down on November 9, 1946 for up-gradation and started again on July 29, 1947. It was operational until October 2, 1955. It was renamed as IEEE Milestone in 1987.
