A modem is an electronic device capable of implementing modulation and demodulation functions required for communication. Once a modem has one end connected to a home terminal or router and the other end connected to a telephone line, in which case its main function is to modulate digital signals sent from the terminal side into analog signals that can be transmitted over the telephone line, and at the same time to convert analog signals sent from the line side into corresponding digital signals that are sent to the terminal side.
