Q. The synchronous modems are more costly than the asynchronous modems because ?
Explanation by: Mr. Dubey
Synchronous modems are more costly than asynchronous modems because they contain clock recovery circuits. Synchronous modems use a clock signal to synchronize the transmission of data between two devices. This allows them to transmit data at higher speeds and with greater efficiency than asynchronous modems, which rely on start and stop bits to signal the beginning and end of each data byte.
