What is the name of the section (direction) with work in the console and packages?

Question

Programming

Good afternoon, tell me, I often see work in the console, where they track data, what is the name of this whole thing?
The bottom line, I would like to see and touch the packages, how it all looks, it is sent when I start the local server and try to upload a picture or download something to it, and in general, I just flip through the pages.
