How the f*ck does a modem work? (alien.top)

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.

Nice concise explanation. Would like to add that a modem originally were useful to be able to modulate and demodulate analog signals to and from digital signals due to limitations on most phone lines to allow for higher speeds than was practical if trying to transmit pure digital signals on them due to bad noise suppression.
