<P> A modem ( modulator -- demodulator ) is a network hardware device that 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 to reproduce the original digital data . Modems can be used with 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 modulated electrical signal for transmission over telephone lines and demodulated by another modem at the receiver side to recover the digital data . </P>
