I just wondering how modems work.
I know the process of "modulation" and "demodulation".
So I wanto know is "demodulation" are simple revese of "modulation" in real world.
The PC can got an IP address when connect as type 1
What will happen when I connect them like type 2?
type 1 :
[PC] ================= [router]
type 2 :
[PC] === [m] ------- [m] === [router]
[m] : modem(exactly same)
=== : Ethernet cable
--- : DSL cable (phone line, maybe optical fiber, or something else?)
ISP has a large number of model, Is them same thing as the one in my home(but with diffrent size/speed/price...etc)? Or it's completely different thing?
