The Computer Concept
abbacus The idea of a computer or a calculating machine is not new!

4500 years ago, the Chinese invented the abacus which is still used in some parts of the world.

Closer in time, the French mathematician Blaise Pascal (1623-1662) invented a calculating machine in 1642.
Babbage's machine In 1822, Charles Babbage (1791-1871) designed "on paper" a machine that could do complex calculations by following a set of instructions and had a memory.
This machine which he called the "Difference Engine", has been built from Babbage's plan and can be seen at the Science Museum in London.
