Explain what modems are and how they work
What will be an ideal response?
Modems are devices that modulate a digital signal into an analog signal on the sending end, and then, at the receiving end, demodulate the signal from analog back to digital. A digital device is at each end of the communication. The term modem stands for modulator/demodulator. As you read earlier, analog signals can be modulated using amplitude, frequency, or phase modulation. Modems also use simplex, half-duplex, or full-duplex connections, depending on the type of modem.
