Basic books for a back end developer?

Question

Books

In general, in the future, there is a desire to study back end development. In particular, working with Node.js.
And so, I decided to open a couple of books on Node, read the introduction. And it was written there that before you start studying this area, you must have knowledge of network protocols.
So, recommend books on those "things" that any back-end developer should know, regardless of the language.

Answer 1

If we talk about networks, then you should:
- know HTTP: at least basic frameworks (authorization, caching, etc.) + basics, methods, headers, message structure, status codes.
- to disassemble the OSI and TCP / IP model at least to the transport layer, well, it might be nice to get a basic understanding of the underlying layers. Well, understand what TLS is.
in principle, everything is in wikipedia, and for details there is the HTTP specification.

Answer 2

Backend - what is needed and what is not?
