Ok, I am assuming that you are a student of some sort, and I will try to understand the question (the translation is p bad)
Ok, to start off, I am going to put the question here
using DNS, the end-to-end TCP/IP protocol communication to communication basic content to each packet packaging format and Internet communication subnet, such as communications equipment characteristics of the theory of knowledge, describe the Internet any two machines in the network communication process. What are the problems that need to be addressed in each step? (write a short essay of more than 800)
From what I can tell, though I am not sure at all considering the question is a mess. It wants you to describe the Internet as a whole, in scaled-down terms of 2 computers, and it wants you to address the way they communicate with each other and show this "theory of knowledge". And give it in terms of steps.
To be honest, I agree with @littlecholla
The question is almost unreadable in the current state. The answer I gave you is my best guess at what it can be asking.
