Explanation-

A modem is a network device that both modulates and demodulates analog carrier signals (called sine waves) for encoding and decoding digital information for processing. Modems accomplish both of these tasks simultaneously and, for this reason, the term modem is a combination of "modulate" and "demodulate."
OR
A modem modulates outgoing digital signals from a computer or other digital device to analog signals for a conventional copper twisted pair telephone line and demodulates the incoming analog signal and converts it to a digital signal for the digital device.

Modem.

Answer : a device that modulates an analog carrier signal to encode digital information.

A modem (modulator-demodulator) is a device that modulates signals to encode digital information and demodulates signals to decode the transmitted information. Modems are generally classified by the amount of data they can send in a given unit of time, usually expressed in bits per second (bit/s,sometimes abbreviated "bps"), or bytes per second (symbol B/s).
