Recently I have received many comments from readers about how to learnOperating system” and”Computer NetworkIn the message, the editor has been learning this piece of content for more than half a year. I have gnawed a lot of books and watched a lot of videos. There are good ones and bad ones. Today, I will present a detailed & clear computer network basic study guide, coveringTCP/UDP protocol, Http protocol, Socket Wait, I hope you will like it.

This time I will share two copies with youMy CollectionThe two notes of”Operating System Study Notes” provide a systematic and comprehensive introduction to the knowledge of the operating system, so they can help beginners get started quickly and improve. At the same time, it tries to interpret the mystery of the operating system from the perspective of philosophical principles, thereby unveiling the mystery of the operating system.

What is the use of learning operating system?

The operating system course is the second most important course for computer majors in addition to computer architecture.

First of all, with the help of os for all our related software, we can first manage the hardware, interaction, communication between programs, and management of memory. And so on, many designs of operating systems are natural good practices. If you can analyze in depth, you can deepen your understanding of software and hardware on the one hand, and on the other hand, you can gain a lot of high-performance software design.

Note:Since there are too many details, only some of the knowledge points are screenshots for a rough introduction. There are more detailed content in the small nodes, so they will not be shown one by one. Fans and friends who need the full version of the”Illustrated Computer Network, Operating System” study notes can forward this article to follow the editor, private message editor [666] Come to receive it! ! !

Compared with operating systems, computer networks are much easier to learn, because computer networks are not abstract. If you want to know the details of the network, you can use Capture packets to analyze, and no matter whether it is a mobile phone, a personal computer, or a server, the computing network protocol used by them is the same.
