In 1614, a Scottish mathematician named John Napier invented a set of rods, which have become known as "Napier's Bones," that could be used to perform complex calculations.
-
During the 17th century, Frenchman Blaise Pascal built a machine that could add numbers up to 8 digits (99,999,999).
-
In 1801, Joseph-Marie Jaquard developed a weaving loom that used punch cards to replicate designs--a revoluntionary step towards computer input.
-
The first machine that actually approximated the idea of a computer, that is, input-execution-output, was conceived in 1832 by Charles Babbage--called the "Difference Engine."
-
In 1890, a punch card calculator was created by Herman Hollerith to count the U.S. Census. Because of this, the U.S. Censes was completed in just 6 weeks!
-
By 1900, several machines had been built rich rivaled the Analytical Engine in complexity. One of theses was invented by William S. Burroughs, and the Burroughs company went on to become one of the leaders in the computer industry.
-
In 1906, Lee De Forest invented the electronic tube. This vacuum tube made possible the development of electronic computers.
-
In 1939, electronic machines where developed for the purpose of breaking German encryption codes. These machines were the forerunners of modern computers.
-
In 1943, a computer developed at Harvard University by Howard H. Aiken was the first programmed controlled calculator.
-
In 1943, a computer named Colossus was completed in Great Britain. This computer took over the task of code breaking.
-
Electronic Numerical Intergrator and Computer. Capable of 100,000 calculations per second.
-
Each transistor could do the work of several electronic tubes, and each was smaller than a postage stamp.
-
Electronic Discrete Variable Computer. First computer to use magnetic tape for storage.
