... messages. Second, its existence was kept secret until decades after the war. American efforts produced more achievement. Howard Aiken, a Harvard engineer working with IBM, succeeded in producing an all-electronic calculator by 1944. Its purpose was to create ballistic charts for the Navy. It was half as long as a football field and contained about five hundred miles of wiring. The Harvard ... -IBM Automatic Sequence Controlled Calculator, or Mark I for short, was an electronic relay computer. It used electromagnetic signals to move mechanical parts. It was slow, taking three to five seco...

... procedures. As early as the 1640's mechanical calculators were being manufactured for sale. Records exist of earlier machines, but it is common belief that Blaise Pascal invented the first commercial calculator, a hand powered adding machine. A step towards automated computing was the development of punched cards, which were first used successfully with computers in the 1890 census. Herman Hollerith of MIT developed ...

... , and their associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job. This machine became known as ENIAC, for Electrical Numerical Integrator And Calculator (Chposky, 1988). It could multiply two numbers at the rate of 300 products per second, by finding the value of each product from a multiplication table stored in its memory. ENIAC ... ...

... and problems that could be answered without the assistance of a computer. Addition and subtraction are no longer figured out by hand, or "in the head", but with the use of a calculator. Likewise, communication is now less personal. Instead of visiting a friend, or calling a person on the phone, society sees e-mail and instant messaging as a "more convenient" way of communicating. Everyday, people ... ...
