Tests / collection of questions on networks?

Question

Computer networks

Interested in what tests / collection of questions can be used to consolidate theoretical knowledge on networks?
If we assume, I can configure something there in Cisco Packet Tracer and roughly understand what and where, but for a theoretical understanding, what can you advise? It is to consolidate THEORY, with practice, I can figure out similar network emulators ...

Answer 1

Understand the network emulator and say out loud what you have done using proper terminology.

Answer 2

This topic is so vast, it is naive to believe that any one questionnaire will cover the entire theory on networks. I've been working with data transfer for 11 years and I understand that I don't know anything)
Banal example - bandwidth, what is it? Depending on the OSI layer, this can be the frequency spectrum of the transmission, bit rate, packet rate, data flow, request transmission)
For self-testing, I recommend completely decomposing in your head how the interaction from your computer to the same toster.ru takes place, which network elements can participate in this, how the formation takes place (what headers and where they are used, what is in the fields of these headers) and packet routing. I advise you to start from the initial premise that your computer is transmitting a stream of bits (if you want, you can also from an electrical signal =). And for each affirmative sentence, ask the question "why is it so."
