COMPUTER

Introduction: Science is the driving force of modern civilisation. It is through the grace of science human race has been raised up to the highest peak. Machine has brought for mankind such comforts as a man can never dream of even in a fairy land. It is not a miracle that machines have come forward to work as a substitute for human brain. This machine is called the computer. Computer is an ultra modern electronic device for storing and analysing information fed into it. It works on the basis of commands given by the computer

How invented: Computer was not invented over night. It took long time and hard labour to invent computer. Many votaries of science worked hard. First of all Pascal invented the theory of ‘Digital Calculating System’ in 1642. Though his attempts were not crowned with success, he initiated the research which paved the way to the invention of computer. Charles Babez, a British Professor of Mathematics, wrote about a formula which could help human brain. Finally, Mr. Howard Akin, an American scientist invented such a machine in 1937 that could do difficult sums. So the credit for the invention of modern computer goes to Howard Akin. After seven years electric computer was used in Harvard University in 1944. After that many other computers have been invented such as EDSAC in 1945 and ENTACE in 1946 etc

Functions of computer: Essentially a computer performs three functions:

1) It receives data (input) 2) It processes data by various computations. 3) It emits data.

These functions are accomplished by giving the computer a programme consisting of a sequence of statements

Major components of a computer: A computer consists of five major components – the input unit, the output unit, the memory unit, the control unit, and the arithmetic unit. The input and output units consist of devices that permit a computer to receive or exhibit information. They may be card readers, magnetic tapes, paper tape readers, line printers, CRT (Cathode Ray Tube) terminals or typewriter consoles. Some of these can be used for both input and output.

Central processing unit: The three units (the memory unit, the control unit and the arithmetic unit) make up the so-called central processing unit. These three units have the following purposes

1)    The memory unit is the component unit where all data and results are stored. Present day computers are called stored programme computers since programmes themselves are also stored in memory. The memory unit consists of many cells, each capable of storing a unit of information (word). These cells, electromagnetic in nature, are also called storage locations (variables). To distinguish cells, they are numbered sequentially. Their numbers are often referred to as addresses. For the user, these addresses are given in terms of symbols (names)

2)    The control unit coordinates all the activities of the various components of the computer. It sends out command and control signals and determines the sequence of the various instructions.

3)    The arithmetic unit consists of electric circuits that perform the various arithmetic and logic operations.

Machine language: Every computer has its own machine language. Instruction to the computer must be given in this language since this is the only language that a computer actually understands. However, this type of language varies from machine to machine and is a function of the hardware of the computer. Programmes written in machine languages are machine dependent, and they are only good for that particular machine

Uses of computer: Computer is of great use to us. It renders great service to mankind. It has lessened our work loads and made our life easy and comfortable. It is used in our daily life for various purposes

a)     In education: Computer is a media of education in the developed countries. The students of the developed countries use computer to prepare their study materials. They learn many things within the shortest possible time. Results of various examinations are prepared accurately with the help of computer within the shortest span of time. It is used in translation. It translates poems or any part of literature. Since 1960, computer has been used in Soviet Russia in translating the news of Soviet newspaper, “The Pravada”

b)     In Medical Science: Now-a-days in developed countries computer is used to diagnose a disease. A newer process of operation has been invented by computer as an alternative of surgery. It is used to grind stones in normal pathological tests.

c)     In Agriculture: Today computer is used in the fields of agriculture in the developed countries. A farmer of America simply puts on the switch of the computer and gets everything done

d)     In Commerce: Now-a-days business, commerce and trade cannot be thought of without computer. It does wonder. It is used to prepare documents to make lists of goods, store information and to prepare budget etc. Management personnel use computer to take decision. The value of currency and price of any share can be known instantly by the computer.

e)     In Printing: Today printing cannot be thought of without computer. It is an indispensable part of printing. At first a book or the subject matter that will be printed is composed with computer. Afterwards the said composed matter is printed on a plate of aluminium or tin and then it is printed on paper with the offset machine. Thousands of books are composed with the help of computer within a very short time. This kind of printing is of high quality

f)      In Industrial sector: In the developed countries computer is used to run mills, factories and industries. Trains and planes are run by the computer. The computer is used to extract minerals

g)     Other uses: Computer is used in various purposes apart from the main ones. It is used in playing chess, cards. Besides, many other interesting games can also be enjoyed with the help of a computer. It is the computer that has made possible auto telecommunication through STD. Today we use a new device, named Internet for speedy transmission of notion in the process of computer network. It is the computer that helps man to conquer the space

h) Source of Income: Computer is a source great income. Many developed and advanced countries export software and hardware and earn a lot

Demerits: There is no unmixed blessings on earth. Everything has its dark sides. Computer has its own demerits. It causes diseases like ”Respitutive Stress Injury” and weakens the eyesight of the operators.

Computer in Bangladesh: Bangladesh is an under developed country. We are far away from the modern science and technologies used in the developed world. Of late, computer has been introduced in Bangladesh. There are off line and on line uses of computer. Many government and non-government offices, educational institutions are using computer. A course on computer has been introduced in secondary and higher secondary levels. Our medical sectors have taken important steps to computerise their work. As a result, we have medical sectors in Bangladesh, C.T. Scan, Ultra Sonography, Electro Cardiography that show the good uses of computers in Bangladesh. Some rich business concerns have taken the steps to get the connection of Internet. Obviously their work is very effective, less time consuming and accurate .The uses of computer in Bangladesh should be properly translated into reality. If all of us can be able to run it easily we will never lag behind.

Conclusion: Science is meant for the service of humanity. Computer is the greatest contribution of science so far made. It is a technical machine. So it should be operated tactfully. It is expected to render the greatest service to humanity by substituting human brain and by saving time and preventing its misuses.

Computer

The Computer is the latest miracle of modern science. The last part of the 20th century will be particularly remembered for this invention, especially as it seems to have a future of endless possibilities. The dictionary meaning of the word ‘Computer’ is ‘an electronic calculation machine’, and it is derived from the verb ‘Computer’ meaning to reckon the number or amount of something. It is indeed the most authentic machine, standing for artificial intelligence but that of a very high order. It is very strange but true that the manner of its operations would suggest that the intelligence and memory it possesses, for surpass those of a living human being.

The work done by the computer covers a very wide field, and its surprising activities are extending to newer shares day by day. Hundreds of calculations, and even of a very complex and difficult type, can be done by a computer in a minute. Again, it seems to possess a prodigious memory. Thousands of pieces of information, and facts and figures can be stored up by it in its memory for an indefinite period, when once these are entered into its ‘artificial brain’. It can recall all that out of its memory at once, whenever required. It is obvious that however extraordinary may be the mathematical genius of a person or however enormous may be the power of his memory, such facts are simply impossible for any human being.

Because of its inconceivable advantages as above noted, the compute is now being used to serve manifold purposes throughout the world, In the Western Countries and in Russia and Japan, its use started a pretty long time ago. India, however, has only just stepped into the computer age. In the advanced countries it is being used in government offices, firms, banks, railways and airlines, educational institutions, scientific laboratories and libraries, etc. Through its very quick and precise calculations the computer has been also playing an important role in the epoch-making ventures of sending cosmonauts to the upper space, and to the Moon.

In our country, too the government and various non-government concerns, institutions, and banks etc. are now using the computer. After the technique of its operations is mastered and its price is lowered down, in India, too as in the West, Russia and Japan, private parties will begin to use it at home. It will then save much domestic labour and much time of the family. Scientists are at work to make the computing machine more and more improved to make it capable of even more difficult and complex operations. It is envisaged that then it will be able to serve an individual by doing various things for him in his daily life from morning, till late at night. It will help in paying electric and telephone bills. it will receive telephone messages and information brought by messengers, record them properly and will deliver the same to persons concerned in time. The robot, or ‘artificial man’, is a recent miracle of science. A robot, already made in USA. And Japan etc. can do the work of many men. Now robot technology is closely allied to the technology of the computer. It appears that in near future, just like the typewriter, the computer will be an indispensable thing in every office and every institution and also in the houses of many advanced families.

In view of the fast growing importance of the computer, both the central and the state governments should do the needful to introduce in Universities and Colleges, courses in computer technology. Students should be taught there everything regarding the computer, its various functions and its future possibilities. As days will pass on, well- equipped persons in computer technology will be required in an ever increasing number by offices, firms, banks and different institutions. The government should also take concrete measures so that computers can be manufactured in our country and at a moderate cost.
