What function does the computer have?

A small box one foot square, with some circuits and zinc plates inside. A century ago, people would definitely throw it into the garbage. But if someone tells them that this is a computer and it is very useful, they will be confused; And when further told that this small box can surf the Internet, get to know the outside world, get information from the outside world, and even it can replace human beings in some ways to solve problems for human beings, they will stare big eyes and look at you with strange eyes, thinking that you are talking about the Arabian Nights. Yes! The development of computers is so fast that our predecessors could not imagine that after their time, there would be an intelligent tool that could change human life and even human history. The original name of computer is computer. Obviously, when people invented it, they just wanted to ease people's computing difficulties through it. However, its inventor never imagined that the large and bulky machine with limited computing power would one day develop into a portable, fully functional and widely used computer in society. The difference between computer and computer is that it is no longer a simple computing tool. It has been endowed with some intelligence by human beings and can replace the human brain in some ways. And this substitution has brought great convenience to mankind. From computer to computer, from huge to exquisite, from single function to complete function, from single machine operation to continuous machine operation, in just a few decades, computers have become popular all over the world and gradually become an indispensable part of people's lives. Throughout modern society, the role of computers is so great that even humans can't catch up in some aspects. Computer is showing its strength and charm to human beings with its solid and tireless style. Nowadays, we can find computers in all walks of life. The role of computers has gradually penetrated into economic, cultural, scientific and technological fields from the initial military field. In car making, manual labor is slow and inaccurate, and the production efficiency is not high. To solve this problem, find a computer; Writing documents, writing again and again, writing again and again, wasting paper, wasting time and energy, and finding a computer after solving it; It is obviously impossible to crack the code of human inheritance and study the chromosome, the carrier of human inheritance. Chromosomes are calculated and analyzed by people. What should I do? Still looking for the computer! Today's computers are really endowed with magical power. It seems to be omniscient, omniscient and omnipotent. It is no exaggeration to say that the reason why human society has developed at an unprecedented speed and made great achievements is inseparable from the role of computers. Computers have done too much work for people, and people are increasingly inseparable from computers. Maybe one day in the future, people will say, "It doesn't matter without food and water, but you can't live without a computer." With a computer, you can enter commands, shop online, or let it cook for you and deliver meals to you. "Maybe now, this is a joke, but who can guarantee that this joke will not become a reality one day and be widely accepted by people? You know, our predecessors did not expect that one day people's production and life would be closely linked with a small box-shaped thing. Society is developing and human beings are making progress. Looking at the ever-changing development speed of computers, even people who manufacture and control computers don't know what it will be like to have computers in the future. This may be beyond human reach! The computer is really a good thing. Its development and progress have promoted the development of human society, and people are proud of the fruitful results achieved by using computers. But the computer is not perfect after all, and it also has defects, just like many things in the world. Computers are not human brains. It has no ability to distinguish right from wrong, and it has no belief in corrosion resistance. It is because it is too loyal that it is used by the bad guys. When we open the mailbox on the Internet, you will find many inexplicable files, which are called junk files. They are all made by network hackers with ulterior motives. Its purpose is both simple and complicated. When it is simple, they just want to disrupt the network order and add chaos to people, so as to show their ability; When it is complicated, they will spy on information and confuse people for political, military and economic purposes. These cyber hackers are really brain-numbing. Because the network is different from reality after all, it is impossible for people to go into the illusory world to track down hackers, let alone cut junk files, which makes people busy as a bee. At this point, the computer is very innocent, because it was originally convenient for people, but it brought trouble to people. Recently, I heard a classmate say a new term-"dizzy screen", saying that sitting in front of the computer for a long time will make me feel unwell. In other words, in the process of using computers, people are unconsciously accepting the harm of computers. From this, I thought of air conditioning disease. They are so similar. So I am very worried that one day there will be computer diseases or other more terrible and strange diseases caused by computers. People can often see that in the computer room, many children are playing computer games with their eyes narrowed. They look tired, but they can't bear to leave the computer. Why? Addicted. I don't know if they are addicted to myopia. A series of harms caused by computers to people all happen unconsciously, and it is impossible to prevent them. So I really want to advise those who develop computer software and computer technology, can you do more protective work to make people happy, secure and comfortable when using computers? What's more, since "Deep Blue" defeated the chess master, people have a panic, and people are worried that computers will one day surpass the human brain and become the master of the world. As a result, all kinds of fantasies emerge one after another, and even science fiction is based on this theme, but this kind of worry is superfluous. Computers are different from human brains. It can't analyze things independently. Without the wisdom of the human brain, it can only be an accessory of the human brain at any time. Everything a computer does must be directed by the human brain. Without people, computers will lose their vitality and vitality. So we can say that the computer is just a tool, and it can't be compared with the human brain at any time. People are always exploring the advantages and disadvantages of computers, just like people are facing other new things. However, no one will deny that the advantages of computers outweigh the disadvantages. The question is what better and more effective measures people will take in the future to make computers serve mankind better and shine more brilliantly. I think there is no end to the development of human history, and there should be no end to human research and thinking about computers. Time flies, time flies. In a blink of an eye, the twentieth century has passed and the twenty-first century is already in front of us. If someone asks me what is the most important thing for mankind in the new century, I will tell him-computer. It will be the darling of the new century, and to some extent, it will determine the future and destiny of mankind. Let's join hands, attach importance to it, cherish it and develop it!
