What Is Computer-Based Learning?

The content of computer technology is very extensive and can be roughly divided into computer system technology, computer device technology, computer component technology and computer assembly technology. Computer technology includes: the basic principles of computing methods and the design of computing units, instruction systems, central processing unit (CPU) designs, pipeline principles and their applications in CPU design, storage systems, buses, and input and output.

The computer is a modern intelligent electronic device with functions of data storage and modification and calculation of related logic and data. Electronic equipment as an integrated network, computing, media and other technologies ^[1]

Technology used by computers as a complete system. There are mainly system structure technology, system management technology, system maintenance technology and system application technology.

System Structure Technology

Its role is to make computer systems obtain good problem-solving efficiency and reasonable

Electronic devices are the physical basis of computer systems. The most basic lines of computer complex logic are AND gates, OR gates, and inverters. The higher-level circuits formed by this are "combination logic" and "

A computer system is made up of a large number and variety of components. The technical content of various components is very rich, mainly including computing and

The assembly technology is closely related to the reliability of the computer system, the convenience of maintenance and debugging, the production technology and the delay of information transmission. The reliability of computer electronic devices decreases with the increase of ambient temperature and humidity. The accumulation of dust may cause short-circuits or disconnections of the plug-in board or the bottom plate. Therefore, refrigeration and air conditioning are important issues to be solved in assembly technology. Commonly used methods are: direct refrigeration method that introduces liquid Freon into the insert cooling fins; water cooling method that uses Freon to cool water and then introduce cold water into the insert cooling fins; use Freon to cool the air and then send cold air into the machine Forced air cooling method of the warehouse. The first two process structures are more complicated, so air cooling is mostly used. Another problem that assembly technology needs to address is increasing assembly density. After the computer device enters the sub-nanosecond level, the signal delay caused by a few centimeters of wire is enough to affect the normal operation of the machine, making the problem of assembly density more prominent. The change of computer electronic devices has a great impact on assembly technology. The advancement of assembly technology has always been in harmony with the replacement of computers, and has continued to develop toward miniaturization and miniaturization. in

On February 14, 1946, the first electronic computer in history, named Kenyan, was born at the University of Pennsylvania in the United States. This computer was designed for missile ballistic calculations. In the 1950s, due to the high cost of computers, the main service target of computers was the military sector, including missile computing and military-related space computing. With the gradual reduction of computer costs, after the 1960s and 1980s, in addition to the use of computers in military units, many government departments and large scientific research institutions, and even some more capable enterprise departments, began to use computers for management. The birth of Intel's four-bit CPU microprocessor promoted the further development and promotion of computers. In 1982, the first personal computer was born. The development of personal computers has caused the cost of the entire computer to drop rapidly. Computers have also shifted from being used only in the military sector and powerful scientific research or enterprise sectors to ordinary small companies and homes. Beginning in the 1990s, many businesses and homes also used computers. At the same time, computers have become polarized: on the one hand, they have become smaller, smaller, and cheaper and have entered the family; on the other hand, they have become higher, harder, and larger, and they are still used in military, science, and technology. ^[3]

Before you learn about computers, you need to eliminate the tension on computers. In fact, learning computers is very easy. Computers are not mysterious. They are just a tool. The internal workings of computers are complicated, but you do nt need to understand those esoteric principles. How to use it, the use of the computer is relatively simple, and using a TV,

1. Basic computer knowledge: proficient in using keyboards and typing Chinese and English characters;

2. Windows; knowledge of operating systems;

3.

Software knowledge development and updates are fast. For example, the operating system software has been updated from DOS2.0 to Windows10 in 1988. In fact, the update of computer knowledge is not a complete makeover. It is just an extension and improvement of the original functions to allow the computer to develop intelligently and closer to people. After mastering the software and mastering the updated software, it uses the newly expanded functions I will know more about computers. I already knew a few things about computers before I learned about computers. It's time to get rid of the nervousness about computers and talk about computer learning methods in a relaxed mood.

Traditional method, step by step

According to the classification of computer knowledge just now, learn from the basics of computer step by step, learn the intermediate level of elementary school, and then learn other branches of computer. This kind of learning may not be effective at the beginning, but later you will feel that you have a more comprehensive understanding of computers, and it is easier to learn other software of computers. In other words, through the accumulation of knowledge, the understanding of computer knowledge has been strengthened. To a certain extent, when you have an understanding of all aspects of computer knowledge, you will feel that computers are just like this.

Learn what you need

If you need some computer knowledge in your work, you can start to learn computer knowledge in this area. You don't need to worry about not knowing other aspects of the computer. By carefully studying the required computer knowledge, you can also learn the computer well and apply it directly to your work. Work and make better grades. This is how computer knowledge can be learned separately. When you are familiar with this knowledge, you can learn computer knowledge on the other hand, which means that you can master the computer completely and thoroughly. A computer is a tool that assists work and life. Learn what you need. This is enough.

Get more on the machine and do more hands-on

The key to learning a computer well is to "use the computer". You must use more computers and do more hands, so that you can apply the computer knowledge you have learned to understand the various spleen nature of the computer. Generally speaking, the ratio of class time to computer learning is 3: 1. If you learn one hour and three hours, the effect is completely different from learning one hour without using the machine. Many problems will be found during the machine operation, and you can improve it yourself. The importance of using the machine is also reflected in the computer, even when you do nt know anything about the computer, you need to use it. As long as you turn on the computer and operate it directly according to the instructions in the book, you can master it in minutes Already.

In short, choose a learning method according to your needs. If you often operate the computer, you will learn the computer quickly, and the computer will become a good helper.
