A hybrid computer uses a Modem to convert digital signals from a computer into analog signals.
Modem, an acronym for modulator/demodulator, is a device that allows one computer to "talk" with another over a standard telephone line. Modems act as a kind of interpreter between a computer and the telephone line. Computers transmit digital data, expressed as electrical impulses, whereas telephones transmit voice frequencies as analog signals.
The conversion from analog to digital technology is one of the most fundamental and dramatic changes in modern media. Digital technology is displacing analog at every stage of the production-distribution-exhibition (PDE) process.
