Modem Card
A modem typically serves as a device that modulates and demodulates signals for internet connectivity, while a sound card is designed to process audio signals for output and input. While some multifunction devices might combine capabilities, a standard modem does not have the hardware or functionality to serve as a sound card. Therefore, while you might find integrated devices with both functions in some cases, a modem itself cannot inherently perform the role of a sound card.

A modem is a serial port interface to a telephone line, allowing you to create dialup connections to other modem equipped computers. Often, a modem card includes a serial port interface, a COM port. The term modem has also become applicable to other interfaces, such as DSL modems and cable modems, though that usage is tenuous in some cases. Modem stands for Modulator/Demodulator.
