Question

Quizplus · Accepted Answer

A modem is a device that modulates digital signals into analog signals and demodulates analog signals into digital signals at the receiving end. A transceiver is a device that can both send and receive signals, but it does not necessarily perform modulation and demodulation. A demuxer and a multiplexer are devices used in digital signal processing to route signals.
