What major should I choose to study computer maintenance?

Oh, to learn computer maintenance, we must first learn the basic knowledge of computers, understand the working principle of each component and judge its quality, and then enter the professional maintenance course step by step. For example, learning desktop mainboard maintenance, monitor maintenance, notebook maintenance, etc. To learn computer maintenance, you must be interested in this aspect first, so that you can learn it well. I am a junior high school graduate. Because I can't find a job when I come out, I prefer computer maintenance after thinking about it. Later, it is better to go to some places to learn about training schools. Finally, I chose Hangzhou Huali Computer Maintenance Training School. First of all, it has a high reputation in terms of geographical environment and local popularity. I also consulted many people and said that this school has it. So I decided to study here.
