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.

Computer key: A modern computer is an instrument that can capture and retrieve numerous data and follow the specific instructions, to analyze the data in mathematical analysis and logical process; With the program fixing itself, it can decide on its own and publish results. 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 nineteenth century, which can only be mechanically calculated mathematically without human help. Badge has given the name of this device to the difference engine. While 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 and its method of operation: The computer manages its work process, mainly through three parts. These are input, central processing unit or CPU and output. The input portion is the data and the instructions are taken. The secondary processing unit (CPU) is the computer's brain. Because all the information in this section is preserved. Basically the CPU completes various processes on data taken and stores data and results. Above all, the output results reveal. The controlling structure of these three parts together is called hardware. Originally all of the external machines, such as monitor, key board, mouse, hard disk, motherboard, scanner, disk, printer, speaker etc. are included in hardware. On the other hand, software programs that are operating and operating on aggregate hardware are called software. In order to solve problems or perform tasks, consistently arranged guidelines are called programs together. Software software is the only program that runs hardware. The computer's amazing functionality is at the core of the combined support of these machines and equipment.

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.

Use of computer in Bangladesh: First time in 1964
