Computer Hardware Terms, Glossary and Dictionary
Fax modem is a computer device that allows for the transmission and receiving of documents as faxes. A fax modem may be installed inside the computer or present as an external modem. Some fax modems also function as regular modems. A fax modem is like a regular modem except that it is designed to transmit documents to a fax machine or to another fax modem. Some, but not all, fax modems do double duty as regular modems. As with regular modems, fax modems can be either internal or external. Internal fax modems are often called fax boards.
