The word 'Modem' is a contraction of the words Modulator-Demodulator. It is typically used to send digital data over a phone line.

The sending modem modulates the digital data from the computer into a signal that is compatible with the phone line and the receiving one demodulates the signal back into digital data. It allows computer terminals all over the world to communicate with each other over phone lines and TV cable.
