Recently, I have studied the book “Interesting Talk network Protocol” written by Professor Liu Chao in Geek Time. Of course, I have only studied the basic part, but I can’t do anything about cloud computing, data center, container and micro services due to my limited skills. As front-end development, learning the basic part is also a benefit, non-combatant first learn here. Below this is the study notes for your reference and review, more detailed content or go to see the course is better, the teacher spoke very good.
Let’s start with the big picture
Layer 2: Data link layer (MAC layer)
Layer 3 (IP Layer)
The transport layer
The application layer
ICMP
conclusion
After learning layers in this way, I will be more impressed by the role of each layer in the network request. If I am asked what I do from entering URL to rendering page, I can also talk about the network level in addition to the browser.
The next learning plan is to learn “The Road to Code Improvement”, to improve the soft power of writing code, after learning will also send their own study notes.
