This device was made by an English mathematician of Cambridge University. His name was Charles Babbage.
The components of this device are a complex system of cogs and lever's which is powered by steam.
its primary purpose is to produce stereotype plates for use in printing presses.
Difference Engine & Analytical Engine
The Difference Engine was developed by Charles Babbage in 1822 AD, which was equal to the size of a room.
The Difference Engine was his first invention and it was powered by a stem.
The Difference Engine was fully automatic for mathematical calculation
it was more than a calculator to perform addition.
it was decimal based machine. i.e. it uses 10 digits 0,1,2,.... 9. in this numbers are representated by wheels. in this each digit has its own wheel. if a wheel comes to rest there would be the jamming of unit means, tehre would be an error. it stops the machine from calculation.
He obtained government funding for the development of Difference Engine due to the importance of numeric tables in ocean navigation.
By promoting their commercial and military navies, the British Government had managed to become the earth’s greatest empire.
Charles Babbage also designed another engine in 1833 AD, but unfortunately he was unable to complete it.
The analytical Engine contained all components as follows.
The store equivalent to memory.
The mill equivalent to CPU.
The input section using punched cards.
The output section using punched cards.
And modern computers are based on it. That’s why, for all his contribution, he is known as “father of Computer”.
