Well, this question, hehe, really can't be as accurate as answering technical questions. However, since you asked, let me give you some advice. To make a statement, I just offer some suggestions for reference, as follows: If you want to learn proficiency well, you must have a specialization in the industry, because the industry is good at it and there are many branches of computers, so it is impossible to learn proficiency in everything (because programming is not an easy task). In addition, there are some hardware and other software. , and software is the floorboard of many aspects, and its connotation is also very wide. I suggest you look at whether you are learning computer because of work needs or interest. If it is for work, you must be interested in the company's appetite and see what is popular. If you are interested, you should also choose specially. If you think about something, you must be incompetent. These are many seniors.
