Computer

Introduction:

Throughout the ages, science has given mankind all the invention of invincible. These discoveries make human life easier by making it easier. The most surprising and efficient invention of these is the computer. This machine, discovered in the twentieth century, is very similar in terms of machine text. The versatile and sophisticated ergonomics, this fast-moving machine is also helpful in controlling waste of time as well as in improving human efficiency and efficiency. The powerful of this machine is relatively easy to use, so it quickly becomes an essential part of human life.

What is the computer:

A modern computer is an instrument that can capture and hold numerous data, and follow the specific instructions, to analyze the data in mathematical analysis and logical process; With the program fixing itself, the decision itself and the results can be revealed. The term computer comes from the Greek word compute. Literally, the word compute means the calculation or counting. In that case, computer money is a calculator. However, currently the computer can not be called counting machine only. Modern computers can do all kinds of work, including data-taking, calculation, analysis and simultaneous data-gathering.

History of Computer Discovery:

Many years of relentless hard work and research of innovative people who have been behind the invention of modern computers have been discovered. Although the ancient people used different techniques in calculating work, the mention of Abacus as the first computation was found in a machine. Later, the French scientist "Basic Pascal" first discovered the mechanical calculator in 1642. Through a series of evolution, Charles began to discover a calculation in the beginning of the 19th century, which can only be mechanically calculated mathematically without human help. Badge has given the name of this device to the difference engine. When researching this machine he got the idea of ​​a more advanced and universal device. However, due to the lack of necessary equipment, he could not make his research concept in reality. However, his planned computing system later gave the idea of ​​modern computer. Originally the modern computer started in 1833.

Computer usage:

Computer usage in everyday life is so great that it can be easily identified as a computer age. In every aspect of modern life, it is possible to see the presence of computers. There is actually no such thing which is not computer. The computer is solving complex calculations of billions of numbers in a few moments. With the help of computer, the bank, insurance, or large factories are responsible for the management plans, instructions, income-expenditure, profit-loss accounts. In the communication system, the computer has become essential in the research institute. Even in the field of education, from the support of textbooks to the results of the test, the results of the test are in full use of the computer. On the one hand, in the medical field, the computer is diagnosing and determining the physical condition of the patient. On the other hand, surgery is also helping. Drawing computer images, editing old pictures, drawing maps, printing and graphics designs, and designing houses, cars, aircraft, sculptures etc. In the case of entertainment, the pair of computer match. At home, cricket, football, racing, and other video games are played on the computer. The work that is impossible to man, the computers which are unable to reach people in the remote areas are also reaching there and the work is being accomplished efficiently. For example, the computer-operated 'scanner' was found to be part of the crashed plane from the Atlantic Ocean. The computer plays a unique role in printing industry. It is possible to know any information about the world by sitting on the computer with the help of internet. Besides, he is also working as a computer assistant for information sharing. Because of the many uses of computers, its integral relationship with modern life has developed. Even a day of modern life can not be imagined without a computer. The multi-tasked computer has given huge civilization to human civilization, tremendous speed and, above all, multiplicity.

Information Technology and Computer:

Computers are intensely related to IT. Over the last two decades, the wonderful world of information technology has been observed in the whole world. It has happened through the use of information technology that has brought the whole world to the hands of human beings. Basically the information related to the collection, storage, analysis and publication of information is known as information technology technology or ICT. And the only way to manage or control this information technology is the computer, especially the Internet. In the information technology and computers, the combination of two pairs has undergone radical changes in human civilization.

Computer problems:

There are two aspects of good and bad. Likewise, modern people, on the one hand, are blessed with computers, while on the other side are troubled by various problems. With the help of computer, some criminals try to create world chaos by creating weapon arms. In addition, computers are being used in condemnation of war-trespass, country occupation, cyber crime etc. Even though the internet has opened up to the young people in the uninterrupted wilderness of knowledge, the propaganda of many weird and obscene cultures is pushing the youth into the path of destruction. Different games, including video games, often make people addicted to drugs. Radioactive emissions from the computer are harmful to the human body. Long-term computer use is harmful for the eye.

Computer education requirements:

Computer education is essential to keep pace with modern civilization. Computer-related knowledge is essential to ensure proper and positive use of computers. As much as people will gain accurate knowledge about computers, computer misuse will be reduced as well. And if the computer can ensure proper use, the progress of the country and the nation will accelerate.

Conclusion:

In this era of modern science it is impossible to stop the computer. Computer use in developing countries has become inevitable. In that case, the application of computer applications should be selected considering the socio-economic conditions of the country. Developing countries like Bangladesh can use the planned design of computers to reach the edge of modern civilization and development.
