Hello dear members !
this threated is about the intrenet which is conveyed by phone lines only. (i mean copper wires)
I have a general idea, that any modem is used to translate the degital signal to analog signal, and vice versa.
I also noticed that each modem needs to be connected, to the phone line
but i got some confuses how that operation occurs , and my main questions are the following :
5)which is better: analog signal, or degital ?

but i got some confuses how that operation occurs , and my main questions are the following :
- does the computer send a degital signal to the phone line firstly, or to the modem ?
- why does the modem understand two signal types: (analog, degital) ?
- why does the dial up modem generate a noisy sound?
5)which is better: analog signal, or degital ?
