What is the name of the program that intercepts the data?

Question

Programming

Need a program that prints all uploaded and downloaded server data to a special console like cmd or root?
For example, I have an online game, when I play it, the computer sends data to the server, and the server gives a response, I need to intercept this data and see what happens)
Maybe there are some special commands for cmd or root, I'll be glad too.
