What OSI layer is a modem?

The modem is works at the Physical Layer of the OSI model. Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The modem is working at the Physical Layer of the OSI model.
