History and Evolution

       History and Evolution

• Historically, the word computer has been derived from the Latin word ‘computere,’ which means to calculate. • Therefore, the term computer can logically be applied to any calculating device.

• The Abacus, the first “automatic” computer was invented in china as a first attempt at automating the counting process.

• Abacus is a machine which allows the user to remember his current state of calculations while performing more • complex mathematical operation.

Pioneers
Gottfried Leibniz Wilhelm, Blaise Pascal, Charles Babbage are the fore fathers of modern computers.

• Blaise Pascal invented one of the first mechanical calculator: The Pascaline

• Gottfried Leibniz Wilhelm invented the binary system which is the foundation of virtually all modern computer architectures. It is used internally by modern computers. Made up of 0s and 1s, it is used for card readers, electric circuits, and vacuum tubes.

• Charles Babbage is credited with invention of the first mechanical computer, called the Difference Engine, which eventually led to more complex and advanced designs. He originated the concept of a programmable computer.
