- Modulator-demodulator(Modem)
- It is an Electronic device that allows computers to communicate over telephones wires or cable-TV cable.
- One computer's modem converts its digital signals into analog signals.
- Other computer's modem reconverts the analog signals into digital signals.
- Conversion of one type of signals to another is called modulation, there re-conversion to the original type is called demodulation.
- Modern modems work at 56 thousand bits per second(kbps) or higher data transfer speeds, and allow voice and fax communications.
