Answer 2

☆ Modem :-

Modems are used to transmit digital information via analog systems. The word “Modem” is derived from the term “modulator-demodulator.” The fundamental elements of a modem are to modulate an analog carrier signal to carry digital data and to demodulate a comparable signal in order to disentangle the digital data from the analog carrier signal. The modem stands for modulator and demodulator. Modulator means that converts digital signals into analog signals and sends them over telephone lines. This process is known as modulation.

▪︎External Modem

▪︎Fax modem

▪︎Dial-up modem
