A modem is a device that lets computers connect to each other over telephone lines by converting digital data into audio signals that can travel through phone networks. In early systems, users would dial a number on their phone and place the handset into the modem, which then transmitted data at relatively slow speeds of 300 bits per second.

A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from LEDs to radio.
