I don’t understand the question. As far as network they work like map.

End Users (PCs) -> Internal cabling (fiber, Cat5, Coax cabling) -> then
from here it get complicated. You need to factor in if it is for home use or business,
number of users, are you build intranet, VLANs. But cables go to a switch
(Cisco maybe) then a Node –> Server (proxy) –> Firewall (Jupiter) –>
to Provider (Verizon).

Also Servers and different types of communication media like microwave
dishes, radio antennas or routers, VoIP, network Video cams.

But really, YouTube, Network+ its a Comptia Cert, that will info you on everything.
