The History of Computers

A computer actually is an electronic device capable of version and executing programmed commands for input, processing, output and even the logical operations. And I would exchangeable to introduce the evolution of computer, and then talk about the generations of it.

During the superannuated period, Abacus was probably the original mechanically skillful counting device, and its effectiveness has withstood the shew of time. Undoubtedly, it is still use to illustrate the principles of counting. Once again, that means the antecedent of the computer is the mechanical device.

Blaise Pascal (1623-62) who was a French mathematician invented a Pascaline which was a first digital computer in 1642. It used gear-driven counting wheels to do addition. The numbers for each digital arrange were arranged on wheels so that a single renewing of one wheel resulted in one tenth of a revolution of the wheel to its immediate left.

Leibniz invented a computer create in 1694 that could add, and, after changing some things around, multiply. It was a surplus stepped gear mechanism for introducing the addend digits, and this is still being used. After that, doubting Thomas created the first successful mechanical calculator that could add, subtract, multiply, and divide.

Then, Charles Babbage (1793-1871) who was a mathematics professor invented Babbages Folly, the Difference Engine was capable of computing numeric tables.



The Analytical Engine could be powered by a locomotive engine and was capable of performing calculation mechanically using preprogrammed instructions with correct sequence on punched card game written by Ada Byron (daughter of the great poet). In addition, the plans for this engine required an identical decimal computer operating on numbers of 50 decimal digits (or words) and having a storage power (memory) of 1,000 such digits.

Afterwards, the Punched card Tabulating Machine was invented in 1980. It was a mechanical computer using punched...
