Answer 1

Tanenbaum - Computer networks

Answer 2

I once bought the "Linux Administrator's Guide" by Evie Nemeth, Garth Snyder and others.
Great book! Now there seem to be slightly more recent editions, I have a red cover.
There, not only on Linux, scripts, and so on, but also on computer networks, network services and about the Internet device in general. And everything is related. It will give the correct sequence (although you can read individual chapters, and not all in a row, I did it) and sort out the existing knowledge in my head and supplement them.
The only thing that is not there to understand the Internet and global networks (although .... maybe there is, but I missed it), is BGP, but you can learn it quite well on your own in a week, there are courses on the Internet.
Well, on networks, "Fundamentals of CISCO Network Technologies", and other courses to prepare for CCNA, CCNP, etc.

Answer 4

It is best to draw the correct picture in your head first, and then learn the information yourself.
Actually google, you don't even have to buy anything:
1) History - the creation of Arpanet.
2) Network physics - coaxial, twisted pair, packet size / what it is limited to, star / bus topology. Duplex, iso/osi model levels. Packet routing.
3) Network protocols - IPX, TCP/IP (IPv4). etc. How DHCP, DNS, ping work, how the network coordinator is elected in LAN. Then the protocols FTP, HTTP, pro hypertext with historical information, SMTP / POP3 / IMAP, newsgroups, instant messengers, a separate theme of China and Wechat instead of WWW.
4) Channels in WiFi networks.
5) Peer-to-peer networks, client-server and serverless.
6) Popular types of WWW servers.
7) Principles of operation of cloud services.
8) Setting up routers, the concept of NAT, port forwarding, and how everything is different with IPv6, VPN and IPSec tunnels.
9) Encryption with ordinary and paired keys. How does the Trusted Party Principle work?
