Paragraph : Computer

Computer

Computer is an ultra-modern electronic device for strong and analysing information fed into it. it has no capacity to do anything by itself. It works on the basis of commands given by the operator. The invention of computer has a long history. Computer was not invented overnight. it took long time and hard labour to invent computer. A computer consists of five major components. They are the input unit, the output unit, the memory unit, the control unit and the arithmetic unit. A computer performs three functions. Firstly, it receives data. Secondly, it processes data by various computations and the third is that emits data. Every computer has a machine language of its own and accordingly it works. Machine language is not fixed. It varies from machine to machine. Computer is of great use to us. It renders great service to mankind. It is like Aladin’s lamp. It has lessened our workloads, saved time and energy and made our life easy and comfortable. We can not go for a single moment without computers. It is part and parcel of our daily life.

A computer is a modern device of information technology as well as data processing and calculating. It is the miracle of modern science. It is operated by software. Without software a computer is useless. Without it modern civilization is meaningless. It is used in every aspect of life. It is used in medical science, engineering, administrative fields, defence, meteorology, astrology, marine science, telecommunication, industrial operation, airways, entertainment, research work etc. It is so fast in calculation that a work which may be done by a computer within a few minutes cannot be done by a man working continuously during his whole life. It has performed an imaginary revolution in the field of information technology. Nowadays Internet is used in innumerable scale. One can get entry to any library or university in anywhere of the world by browsing a computer sitting in Bangladesh. Online communication is a great advantage for us. It can connect whole the world at a glance. We can visit whole the world just sitting in front of it. It is the indispensable part of our modern life.

The word computer is derived from the Latin word ‘computare’. It means calculating machine. It is an ultra-modern electronic device for storing analysing information fed into it. It cannot do anything by itself. It works on the basis of commands given by the invented overnight. Charles Babez, a British professor of Mathematics invented computer. The modern computer was invented by the American scientist Howard Akin. A computer consists of five major components. They are input, output, memory, control and the arithmetic unit. A computer performs three functions. It receives data, processes data by various computations and emits data. Every computer has machine language. It is not fixed. It varies from machine to machine. Computer is of great use to us. It renders great service to mankind. It is like Aladin’s lamp. It has lessened our workloads, saved time and energy and made our life easy and comfortable. We cannot go a single moment without computer. It is the part and parcel of our life.
