Hey guys, this is Programmer Cxuan, welcome to my latest article.

If you are familiar with me, you may know that I have learned six PDFS, including Java Basics, Java Advanced, HTTP, Computer basics, operating system and summary of questions.

Many friends have downloaded, read and corrected these six PDFS, and even printed them in color. But to be fair, these six PDFS are not enough for me to talk about over dinner, because I’m not always satisfied with the structure of the articles, some typos, and even some misunderstandings. I apologize here.

In the later time, I will constantly iterate and revise the problems and mistakes in the previous PDF, and try to hand over all the knowledge I know to you.

However, this article is not an apology post, but I want to announce something. It has been eight months since the public account cxuan, a programmer, published the first content related to computer network on October 19, 2020.

I serialized about 16 articles on computer networks. During the serialization process, many friends asked when the PDF version would be available.

I have been waiting, I want to reduce errata as much as possible, I want to reduce typos as much as possible, I want to give you a better PDF, so that you can more easily accept the course “Computer Network” system.

Most important: you won’t have to worry about page numbers anymore.

Yes, the computer Network PDF is a paginated PDF, isn’t it a bit impatient?

You read that right. The PDF has 226 pages, which I think is about the number of pages in a published book.

The whole PDF is divided into 11 chapters

Each chapter has a brain map that takes you through the entire chapter.

I will peer down from the top of the computer network, gradually explore the structure of each layer, the connections between layers, talk about the important protocols in the computer network, and finally through a Web request process to connect the entire knowledge structure of the computer network, take you to build the computer foundation.

The publication of this PDF is not possible without the help of a very good little sister, she helped me to go through the whole PDF, put forward a lot of structural system and unclear concepts and so on modification suggestions, I respect her very much!

And very humble.

Heartfelt thanks to all the friends who support programmer Cxuan. Now I will announce how to get this PDF:
