The modem (modulator-demodulator) is the device that modulates the analog carrier signal to encode digital information, and demodulates the same carrier signal to decode the transmitted information. The modem is one of the most important hardware that is used by the computer to specially to facilitate signal transmission so that it can be decoded to produce the digital information. The file hsf_dp.sys is called upon by an executable command that calls on the codecs that are necessary to support the functionality of the modem from Conexant Systems, which is a data fax modem. The driver for the fax modem enables the computer to receive and transmit documents as facsimile messages. The fax modem is like a data modem but is designed to transmit and receive documents to and from a fax machine or another fax modem.
