IT practitioners are people engaged in IT-related careers, such as teachers and students of computer colleges, bosses and employees of computer enterprises and network enterprises, various personnel of communications companies, and so on. As IT technology has penetrated into various industries and fields, not only IT undertakers, but also all normal people should understand the accurate role and significance of computer systems in the universe and life. Especially with the advent of the fourth Industrial Revolution, the popularization of computer systems is becoming more and more comprehensive and extensive, and it is even more necessary to realize what is the original intention of people to invent and use computer systems. Only after doing so, I will not be confused and ignorant in the study and work of IT career. For example, modern computer systems include supercomputers in scientific research institutes, national defense supercomputing departments, various mobile and smart phone mainframes, minicomputers, rack servers, workstations, personal computers, embedded devices, and so on. Whatever needs to use the function of fast and accurate calculation first will be a modern computer system. Keeping in mind the original ideal and ambition, the first function of the computer system is: first, to calculate the operation problems designed by humans quickly, accurately and automatically according to the patterns designed by human beings, so as to save the time of manual operation and improve the efficiency of people in processing information. At first, the computer was invented by scientists in the military department to calculate the trajectory. If the computer cannot calculate quickly and accurately, is slower than people, and is inefficient, then there is no need for invention. And scientists knew that the computer would calculate very fast, so they invented it. Sure enough, the computer has gradually developed from the slow computing speed at the beginning, and the computing speed is getting faster and faster and the efficiency is higher. It should also be noted that digital computing and mathematical operations belong to 100% of people's information processing, because there are actually no numbers in nature, and numbers are information invented by human beings. Digital computing is the processing of information) second, modern computer systems have already gone beyond the first function. Several more important core functions are added: 1. According to the human design model, it can realize the long-distance communication or the rapid and accurate transmission of data and information between the two people in real time or offline. The transmission of information includes the transmission and output of pictures, sound, music, and so on. for example, a song is a piece of information, which can be copied and transmitted to the computers of many people in the distance. Pictures and videos can be accurately and completely displayed through the monitor, and so on, a large number of all kinds of information can be transmitted and output quickly and accurately. Communication needless to say, phone calls, QQ, Wechat, can achieve more than a thousand people real-time and offline group chat) 2, to help people organize information. For example, photoshop software, office series tool software, etc., can allow people to organize information on the computer. Organize documents, modify pictures, etc. 3. Long-term, accurate and safe storage of information data. It can be done by storing data on hard disk. It is also carried out according to the human design pattern. Because the whole computer system is a model designed by human beings. 4. Capture information quickly and accurately. Mouse and keyboard input enables the computer to quickly and accurately capture information such as thoughts and words that people want to convey, camera photography can quickly capture image information, microphone recording can quickly capture sound information, and so on. The computer has the functions of cameras, tape recorders and other machines. Other machines can be connected to the computer. Nowadays, the Internet of things is that the probe of the computer system quickly and accurately captures the position and movement of various objects and other information, and then immediately transmits it to the cloud for storage, calculation, sorting and other information processing. 5. Accurately control the machinery according to the human design pattern. All kinds of embedded machines, industrial mechanical arms and so on. The computer itself is a machine, the operating system is to control this cold machine to move, how to move, how to run, are all designed by people. The computer focuses on the processing of information (such as mathematical logic program operations, controlling how the screen displays image text, and controlling how data is transmitted over the Internet), while industrial robot arms and embedded machines, computer systems, will also control the real movement of physical equipment. Third, the computer is a machine, of course, will not be tired, can run for a long time, as long as there is electricity. But there will be a glitch. However, under the condition of modern refined equipment, the fault occurrence rate has been able to be very low. This is much better than people. People can't work 24 hours a day. Therefore, the computer system can obviously improve the efficiency of work. On the other hand, the operation and maintenance personnel should ensure that the computer system can operate stably without downtime 24 hours a day. Here's another explanation, according to the pattern of human design. How to run the computer's CPU, memory, motherboard, network, hard disk, monitor, keyboard, programs, etc., are all designed by people. Computers used to run in the same way that people designed in the past, and now they run in the same way that people design now. Do not forget the original ideals and aspirations, and then return to human existence, life, activities. Computers that efficiently transmit and process data can develop rapidly, extensively and deeply, because people's various activities of survival and life can be carried out. It is necessary to obtain and process a large amount of information (for example, the simplest eyes get information, and then the brain processes the information and then makes decisions about action. If he is blind, he cannot process the information if he does not have access to it. You can't do a lot of things. And computers can help people finish this process efficiently.
