The leaders of the computer

1822
Charles Babbage propose an idea about the tools that can help men perform in a complex calculation. The engine is not finished at this time made in the London Museum of Science.

1937
Dr. John V Atanasoff and Clifford Berry designed the first electronic digital computer. With the ABC (Atanasoff-Berry Computer). ABC can only calculate and add less.

1943
During World War 2, a British scientist named Alan Turing electronic computer designed specifically for the UK army. Code used to penetrate German defense.

1944
Howard Hathaway Aiken (american) make Mark I. A first digital calculating machine that is made. Has a 7.45 feet wide x 50 feet, with a weight of 35 tons. Mark I can be used to calculate the probability.

1945
Dr. John von Neumann concept of write data storage. When the idea was still in form.

1946
Dr. John W. Mauchly and J. Presper Eckert, jr. complete large-scale computer first, given name of ENIAC (Electronic Numerical Integrator And Computer). The world knows these two men as the inventors computer.
ENIAC weight 30 tons, consisting of 18,000 light tube (transistor size), has a 30 foot wide x 50 feet, use of 160,000 watts. The first time the computer is switched on, the entire electricity network in the Philadelphia sudden death.
ENIAC could calculate not only to less time for, but can also be programmed to perform a simple process. Compared to the Mark I can only calculate, can be seen that the ENIAC was the first computer in the world.

1947
Found by the first transistor William Shockley, John Bardeen and Walter Brattain. Since the transistor is found, the size of the computer off ..

From reading above, the inventors note that the computer (not a calculator) is a PhD. John W. Mauchly and J. Presper Eckert, jr ..
