What is a computer? How does a computer work?

A computer is an electronic device used to store data, and it gives fast and accurate results according to the instructions given.
The computer is widely used and very important in daily life. Due to the current era of information and technology dependence, the demand for it is increasing daily. What is a computer for most people? Even if you know about it, how does the computer work? Many people are unaware of its types and usage. In today’s post, we will discuss them in detail. Let’s find out. A computer is a device that can perform mathematical calculations very quickly by following specific instructions. The word computer comes from the Greek word “compute.” The word compute means to calculate. And the word computer means calculating device. But computers are no longer just calculators. A computer is a device that receives information and analyzes and presents it through various processes. At the heart of the development of civilization and its rapid progress at present is the strong influence of mathematics and computers. The first computer came to Bangladesh in 1974. Scientist Charles Babbage gave the first idea of ​​making a computer. In 1833, he planned to build the first mechanical computer called Analytical Engine and designed the engine. Today’s modern computers are based on their designs and computers. Charles Babbage is called the father of computers because he had ​​a modern computer in his design of this analytical engine.
On the other hand, John von Neumann is called the father of modern computers. He is an American mathematician of Hungarian descent. Newman is a pioneer in the use of operator theory in quantum mechanics. He has contributed to many fields, including set theory, geometry, flowing dynamics, economics, interactive programming, computer science, statistics, and many more. The first computer in the world is called ENIAC (Electronic Numerical Integrator and Computer). This is the first digital computer to work with the program. From then on, the computer generation started. During World War II, when the U.S. military planned to build a fully electronic computer, computer giants such as Von Newman, the father of modern computers, Presper Eckertie Jr., and Herman Goldstein joined the Moore School of the Electrical Engineering University of Pennsylvania. Forty scientists operated this three-walled computer in an underground room of fifty feet by thirty feet.
Computers usually perform a combination of two mediums. Discussed with examples below. First, hardware: All the devices, parts, and devices with the external shape are called hardware. Computer hardware can again be divided into three parts.
A) Input equipment: keyboard, mouse, disk, scanner, card reader, digital camera, etc.
B) System unit: hard disk, motherboard, AGP card, RAM, etc.
D) Output equipment: monitor, printer, disk, speaker, projector, headphone, etc. Second, Software: A program is a series of instructions arranged in a computer language to solve problems or perform tasks. Software is the program or set of programs that make the hardware work by creating a relationship between the computer’s hardware and the user. Computer software can be divided into two main parts. A) System software: System software is the ability of a computer to execute practical programs by maintaining the coordination of work between different units of the computer) Application software: A program used to solve practical problems or process data is called application software. A variety of programs designed to solve practical problems are available as commercial products, also commonly referred to as package programs. So a computer is a combination of hardware and software.
How to keep engaged. Man uses a computer to improve his work. So the use of computers is increasing day by day. The following are the different types of computer use: — Office Management, Education, Industry, Medicine, Agriculture, Research, Military, Statistics, Design, Programming, Printing, Communication, Banking, Culture and Entertainment, Courts, Finance, Weather Forecast. In a word, computers have a lot of uses. Its immense use in various fields is starting from housework to business, scientific, etc. Above all, it has brought a unique revolution in the field of communication. It is also a unique companion in medical and human welfare. In a word, a computer is a device that is capable of doing almost everything.
