Modem A modem (Modulator-Demodulator) is a device that
modulates signal to encode digital information & demodulates signal to decode the transmitted information.
Modem’s task is to produce a signal that can be transmitted easily & decoded to produce original digital data.
Modem can be used with any means of transmitting analog signals, from LED to radio.
For computer, modem converts the digital data into modulated electrical signal for transmission over telephones lines & demodulated by another modem at the receiver side to recover the digital data.
