It depends on what you want to do. If you want to engage in scientific research or college education in the future, then it is necessary to take the postgraduate entrance examination, and you will have to study for a Ph.D. in the future. If you want to get a job, then take a look at the job you most hope to get. What are the requirements? For example, some state-owned enterprises, public institutions, and civil servants require a master's degree if they want to stay in the provincial capital city, so go for it. If you want a job that you are satisfied with, you don't need a master's degree, then I suggest you just work directly, because What is important in the computer field is programming experience. This work experience and the experience of working on projects with teachers at the master's level are much stronger.

The postgraduate stage mainly depends on what your teacher does. Basically, you help the teacher with projects, and you learn experience and things from the project. As for the specific work, it depends on your direction, software, hardware, embedded, artificial intelligence, data mining, many directions, I hope it can help you
