A Short Composition about Computer

Introduction:

it is the age of science. Science is the driving force of modern civilization. By the blessing of science, we can talk over the phone or internet and send a message across the seas. Due to science man has landed on the moon and Mars. He has invented the computer. It is the latest miracle in science and technology.

How invented:

Charles Babes, a British professor of Mathematics, first thought about a formula. The formula was supposed to help the human brain. He could not invent the computer. He initiated the research leading to the invention of the computer. But the credit for the invention of the modern computer goes to an American scientist. He is Mr. Howard Akin. In 1933, he invented such the machine that could do difficult sums. After the seven-year electric computer was used in Harvard in 1944.

The function of a computer: 

Generally, a computer performs the function. It receives data. It processes data by various computations. And emits data.

Major components of a computer:

The computer consists of five major components. They are input unit, an output unit, a memory unit, control unit, and the arithmetic unit.

Machine language of Computer:

Every computer has its own machine language. It understands only this language. So, an instruction to the computer must be given in this language.

It's user:

computer serve us in many ways. It is used in translation. It translated poems or any part literature. It is used in big agricultural farms in America. Trains and planted are run by computer. The result of examination can accurately be given by computer within a short time. Tine is not far off when every brain work will be done by computer.

The computer in Bangladesh:

Today computer is very much popular in Bangladesh. It has already occupied a place in the mind of the people. The young generation is very conscious of computer education. They are receiving training in computing with great interest.

Conclusion:

The computer is the greatest contribution to science. And we should buy computers, use the computer and try to make computers for the prosperity of the country.

The Computer The Invention 

Science has given us many wonders. it has made out life easy and comfortable. Computer is a new invention of modern science. We cannot think of a day without it. It cannot work by itself. It works according to the command of the operator.

A single scientist has not invented it. Many scientists have worked to invent it. Charles Babes is the father of modem computer. He invented the structure of computer in 1833.
computer has five major parts. They are the input unit, output unit, the memory unit, the control unit, and the arithmetic unit. A computer has three functions: (i) it receives data (ii) it processes data and (iii) it emits data.

Computer helps us in education, communication, entertainment etc. Students prepare their study materials by using computer. Students can use the internet through computer. Students can use internist through computer. Students can get much information from interned, On the other hand, doctors use computer to diagnose disease. It has invented a new kind of operating system. So in many cases, we need not surgery.

Again, e-commerce is a very common idea in business. Computer has made it easy. We can know the price of currency and share through computer. It is very essential in banking system. Many documents and information are stored in it.

Computer is a good source of entertainment. We can watch movies and listen to songs on computer.
There are many advantages to computer. But it has some demerits. It weakens the eye power of the operator. Students waste their valuable time by using computer.


But it is true that computer is a blessing for us. it has given motion to our life. It has made the world smaller to us. To build a digital Bangladesh we should know the use of it.
