Where to read about network technologies, as they say, in a nutshell (to keep it short and simple)?

Question

Computer networks

Maybe I want a lot, but there are resources or something where it is written about all this in a nutshell and in simple language. I'm not too lazy to read big books, I saw good ones advised here, but first I would like to understand briefly how it all works. DNS, DHCP, how the network is built in the enterprise, about routers, switches, etc. Or I will be grateful if someone simply writes in their own words about important concepts in this area.
