the Linux understanding of the system:

Linux system is a support multi-user, multi-threaded excellent operating system, the function is very powerful and perfect, these features are provided by the Linux kernel. After years of development, the Linux kernel has been streamlined and optimized to form a complete system. It provides users with the following aspects of functional assurance: memory management, process scheduling, file system, device management, network management. In this course, the teacher focused on a little, mainly on the process and process scheduling this aspect of knowledge, let us know what is the process, the relationship between the process and the executable program, how the executable program starts, how the system calls, process scheduling process and so on.

First thoughtful Eighth Week blog Job Directory:

I. Analyze the assembly code to understand how a computer works

Second, understand how the operating system is working

Third, follow-up analysis of the Linux kernel boot process

Iv. using the same system call using the Library function API and the embed assembly code in C code two ways

Learning experience:

After studying this course, I have deepened my understanding of the operating system theory, know how the Linux system works, understand some simple kernel code, and remember some of the operation instructions of the Linux command line interface. In this course, taught me more is the learning method, that is, from where to start learning the Linux kernel, the course gives us a lot of this hint, such as: How to debug the kernel, how to understand the kernel of the assembly code, how to analyze system calls and so on. After a few weeks of study, personally feel benefited, hope that in the future can also learn more about Linux.
