Introduction to operating systems, operating system concepts

A computer system can receive and store information according to human requirements. It can process and provide the required results. The results (output information) depend on the received information (input information) and corresponding processing methods.

1. Learning Process:

I used to learn some related operating system knowledge at the beginning of Computer Level 4. This is a simple review. In the course of this study, I learned the details I have not previously read. Next I will perform a general review, and then I will learn and summarize the distribution of each unit.

In the first unit of study, we will give a brief introduction to the operating system knowledge, which is a relatively simple prerequisite. Next we will follow the step-by-step learning method, sort out and summarize the learned knowledge:

In the second unit of learning, we mainly describe the processor. The general knowledge is presented in mind maps. in this unit, we will mainly learn the simple concepts of Processor Scheduling, interrupt and processing, control blocks and threads:

In Unit 3, I learned how to manage storage and how to use and store storage. This is the focus of operating systems, when calculation questions occur in the examination, you need to strengthen understanding and understanding:

In the fourth unit of study, we will learn about file management, including the organization, space allocation, directory, and security of files. I feel that this part of learning is relatively simple, however, we need to enhance the knowledge:

In Unit 5, we will talk about the management of learning devices, I personally think this part of knowledge is important, including device allocation, drive scheduling of disks, startup and I/O interrupt handling of devices, buffering technology, and virtual devices, it is not easy to master related device management. We need to make some effort:

The last unit will be used to learn concurrent processes. It will mainly master the functions and allocation methods of concurrent processes, the introduction of communication, and some knowledge about deadlocks, in the course of this chapter, I still feel a lot of pressure. The process knowledge is a bit difficult, but it is a good embodiment of our patience and we have enough ability to do it well:

2. Summary

Learning the operating system is still quite slow. It seems that when I first got into the advanced class, I learned some related hardware knowledge and combined hardware and software. Of course, in this study and summary, I also learned a lot of first-off knowledge that I have not carefully studied. It is very helpful for the future study of the operating system and the examination preparation. We also hope that your learning will reflect our patience and be able to do better!
