The basic language of modems and dial-up remote access systems is:
A.
Asynchronous Communication.
B.
Synchronous Communication.
C.
Asynchronous Interaction.
D.
Synchronous Interaction.
Explanation:
Asynchronous start-stop is the physical layer used to connect computers to modems for many dial-up Internet
access applications, using a data link framing protocol.
Incorrect Answers:
B: Dial-up modems use Asynchronous, not synchronous, communication.
C: Dial-up modems connect to a remote system using communication, not interaction.
D: Dial-up modems connect to a remote system using communication, not interaction.https://en.wikipedia.org/wiki/Asynchronous_serial_communication
