The correct answer is Modem.A Modem is used to transfer the digital signals between the computer and the communications channel.A modem is a short form of modulator-demodulator.It is a hardware device that converts data from a digital format, intended for communication directly between devices with specialized wiring, into one suitable for a transmission medium such as telephone lines or radio.A modem modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information.The goal is to produce a signal that can be transmitted easily and decoded reliably to reproduce the original digital data.Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio.A common type of modem is one that turns the digital data of a computer into a modulated electrical signal for transmission over telephone lines, to be demodulated by another modem at the receiver side to recover the digital data.
