1, Computer Hardware: Learn computer hardware including computer components, such as central processing unit (CPU), memory, hard disk, monitor, etc. , its function and working principle. Understanding computer hardware is very important for understanding the working principle of computer system and for hardware maintenance and troubleshooting.

2. Operating system: learn the functions and concepts of operating system, such as process management, file system, memory management, device management, etc. Mastering the knowledge of operating system is helpful to understand the operating mechanism of computer system and improve the performance of the system.

3. Network communication: Learning network communication includes the basic concepts of computer networks, network protocols, network topology, network security, etc. Understanding network communication is helpful to understand the working principle of the Internet and the development and management of network applications.

4. Data structures and algorithms: Learning data structures and algorithms includes the principles and implementation of various data structures (such as arrays, linked lists, stacks, queues, trees, graphs, etc.). ), and the design and analysis of common algorithms (such as sorting, searching, graph algorithm, etc.). ). Mastering data structures and algorithms can improve the efficiency and quality of programs.

5. Programming language: Learning programming language includes the grammar and semantics of programming language, and how to use programming language to write programs. Common programming languages are C, C++, Java, Python and so on. Mastering programming language can realize your own ideas and solve practical problems.

The method of learning computer

1. Self-study: You can learn computer knowledge by reading related books, tutorials and online resources. The advantage of self-study is that you can learn according to your own progress and interest, but you need enough self-discipline and perseverance.

2. Study in class: You can choose to apply for computer-related training courses, courses or computer majors in universities. In the classroom, you can get systematic learning guidance and opportunities for interactive communication, but it takes some time and economic investment.

3. Practical projects: Learn by participating in computer practical projects. You can choose to participate in open source projects and do some small projects yourself, so that you can exercise your practical operation ability and problem-solving ability.
