Google searches have only yielded 5th grade level examples (“the modem talks between your ISP and your home network!”) or articles I would need a degree to understand. Can anyone provide an explanation that’s somewhere in between the two? I understand the fundamentals of how the Internet works, and how LAN works regarding a router and individual devices, but I’m curious to know more about the link between those.
Let’s use a non-techy example. I speak English (your home network for this analogy), and I’m trying to converse with a person who speaks Chinese (the wider internet). Neither of us understands the other’s language, leading me to find someone who speaks both to interpret (the modem). The interpreter listens to what I have to say and then repeats it to the other party in Chinese. The Chinese person gives a response, which the interpreter repeats back to me in English.
