Computer – Demand of The Modern Era
Today’s world is the era of science. Science has created any miraculous inventions. One of them is the ‘Computer’. It has made man’s life easy and comfortable.
In 1662, a mathematician of France built a machine which could add numbers. The man was Blaze Pascal. Another scientist of England called Charles Babbage tried to invent a machine called the computer, but he couldn’t succeed. The credit of building the modern computer goes to three persons – Mr P. Icrate, Mr John W. Mackley and Mr. G.V. Newman. With their joint co-operation and efforts in 1944, a machine was built. It was named ‘Electronic & Computer’. Then improvements followed one after the other.
A computer calculates, adds, subtracts and multiplies numbers very quickly and correctly. First of all a computer reads what work it has to do. It keeps the order/work in its memory. Then it works according to the given order or instruction. The success of a computer depends on solving the sums swiftly and correctly without any mistake. In brief, the function of a computer depends on its memory.
