HomeSystem TutorialLINUXAnalyze the design principles of separation of resource management and strategy in operating system courses

1. Why should you study this course?

We are in the era of concurrent processing, and programming of processes, threads, interpreters, etc.Linux operating system principles and applications has gradually become a basic skill, which involves resource competition and sharing, deadlock and other issues, all of which This is what the OS course is about; OS's resource management of software and hardware is its main function. By learning resource management, you can reuse this model in many other situations; when there are performance problems in the system or program, Or when a conflict occurs in the system, you have to go deep into the system to see how it is handled. In this way, the grasp of the operating system principles becomes extremely rare.

Designing any engineering system, including software systems, is a process of trade-offs. Is it to focus on reliability? performance? Consumption or maintainability? Because the operating system is a very large, performance-critical program that usually needs to be maintained for several years or six years, the operating system is a good place for you to learn these trade-offs. Middle school students with a pair of sharp eyes who can find suitable design points are very necessary in industry. Those people are more like artists than scientists. You need to read a lot of code, understand these problems, and learn to think about these problems independently. 2.What are the topics of this course?

linux操作系统原理及应用_操作系统及linux应用_linux操作系统原理及应用This course is based on the resource management of the operating system, involving five subsystems: process management, video memory management, file management, device management, and operating system sockets. It implements the design concept of separation of mechanisms and strategies. This concept is based on computer science. The basic design concept, so what are the mechanisms and what are the strategies of linux qq, the mechanism is what kind of functions it provides, and the strategy is how to use or realize this function. For example, the high school entrance examination is a mechanism, and you go to the exam according to the rules of the high school entrance examination. It is a strategy. For example, the read() provided by the file system is a mechanism, and when you call the read() function to read data from the c drive, it is a strategy, and so on. So, does the operating system course teach mechanisms or strategies? Focusing on the mechanism, if you can apply this mechanism, you will get greater gains. If you can design a mechanism, it will be a major innovation.

3. What can you get from studying this course? Especially what help and application it has for myself.

1) Helps in compiling concurrent programs

linux操作系统原理及应用_linux操作系统原理及应用_操作系统及linux应用Whether you are learning Java, Python, or C, especially the Go language, thread concurrency control is a difficult point, and the explanation of concurrency in the language itself is limited to the introduction of specific functions, and cannot go into depth into the principles and some of its fundamentals. Concepts such as critical sections, critical resources, synchronization and mutual exclusion are actually something that must be learned thoroughly in the operating system. Just focus on the basics and not worry about the end.

2) Helps cultivate systematic thinking

The operating system manages the computer's software and hardware resources from the perspective of resource management. Software and hardware collaboration and management are the main battlefield in the design of the operating system. Therefore, there must be systematic thinking and a deep understanding of both software and hardware. Understanding, such as CPU management (that is, process management), and video memory management, all need to be designed based on an in-depth understanding of the relevant hardware and the application of holistic thinking in the system software, so that the software and hardware can truly collaborate. This is a very complex problem. systems engineering.

3) Helps develop the ability to analyze system performance

Currently, computers are used in a wide range of applications, including artificial intelligence, blockchain, cloud estimation and big data. The bottom layer is supported by the operating system, especially the open source operating system Linux. In practical applications, you will find that there are many performance problems that need to be solved, but the solution to these problems will eventually be traced to the operating system level. For this reason, mastering the knowledge and skills of the operating system is the cornerstone of system performance optimization.

4. What are the features and highlights of this course?

linux操作系统原理及应用_linux操作系统原理及应用_操作系统及linux应用

1) Break the rote memorization situation of exam-oriented teaching of operating systems and stimulate the initiative and enthusiasm of middle school students in learning operating systems.

This course has pointed out from the beginning that it is necessary to break the exam-oriented education, and starts from the innovative design of each assignment. The completion of assignments is a series of links, and there are no ready-made answers. Through the training of large assignments, the concepts can be put into practice. Sound.

2) Improve the ability of middle school students to comprehensively apply knowledge to analyze and solve problems by using the Linux version from point to point.

linux操作系统原理及应用_linux操作系统原理及应用_操作系统及linux应用

The knowledge points of the operating system are relatively scattered. How to apply this knowledge point? The course has been carefully designed in each experimental link. For specific experiments, please refer to the operating system experiment in the laboratory building. Subsequent experiments are all iterations of the previous one. As they continue to grow, the above knowledge is comprehensively applied, so that middle school students gradually acquire the ability to solve complex problems.

3) Improve middle school students’ ability to proactively solve problems and increase their awareness of innovation.

In the design of assignments and experiments, a certain amount of space is left for middle school students. For example, each assignment must ask 2 questions by themselves. The challenging experiments are steep and require a large amount of information to be completed. . The innovative consciousness of middle school students has been strengthened.

4) Improved teamwork and communication skills.

Many assignments and experiments are completed in groups and each group reviews their assignments. Each group has its own name and slogan, and the group name and slogan will accompany the group for one semester. Everyone has a clear role and responsibility in the group, which encourages middle school students to experience corporate culture and responsibility during the learning process.

Learning Linux is not difficult. 1.Linux is an open source operating system based on Unix and is widely used in servers, embedded systems and personal computers. 2. Understanding file system and permission management is the key. The file system is hierarchical, and permissions include reading, writing and execution. 3. Package management systems such as apt and dnf make software management convenient. 4. Process management is implemented through ps and top commands. 5. Start learning from basic commands such as mkdir, cd, touch and nano, and then try advanced usage such as shell scripts and text processing. 6. Common errors such as permission problems can be solved through sudo and chmod. 7. Performance optimization suggestions include using htop to monitor resources, cleaning unnecessary files, and using sy
