Fax modems are devices that allow computers to send and receive fax messages over telephone lines. These modems work by converting digital data from the computer into analog signals that can be transmitted over a phone line. They are commonly used in offices and homes that still rely on fax machines for communication, and they can also be used to send and receive faxes via email. Some fax modems also offer additional features such as voice messaging and caller ID. With the rise of digital communication, fax modems may not be as popular as they once were, but they still provide a reliable way to send and receive important documents.
