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.

A modem allows computer terminals all over the world to communicate with each other over phone lines and TV cable.
