The relationship between modem and ADSL

First of all, ADSL is a networking technology, while a modem is a device...

ADSL is a technology that enables digital signals transmitted by computers to be transmitted over traditional analog networks (i.e., traditional landline networks), using a method that uses a higher frequency band than that of voice transmission, which is not used in traditional analog telephone networks, to transmit data information...

And the modem, as you say, is simply a device that provides analog signals and digital signals to each other, and it can also be said that if you use ADSL as a network technology, the modem is one of the devices to achieve this technology ...

Of course, the modem is not only used in ADSL, a long time ago, we do not have broadband when there is a modem, but because there was no ADSL technology, so the data signal in the computer is taking up the frequency band of the voice signal to transmit, so when we surf the Internet, you can not make a phone call .... But because of the current ADSL technology, the data and voice signals use different frequency bands, so they generally do not affect each other, so now we use the computer to access the Internet at the same time you can also call...

The above is my understanding, I hope the owner can understand ...
