Definition of "Modem" |
A hardware device that converts digital computer data into analog tones that can be transmitted over dial-up telephone circuits. / A circuit or device that performs both modulation and Demodulation. See also Modem Specifications. A device used for converting digital, signals into, and recovering them from, quasi-analog signals suitable for transmission over analog communications channels. / MODulator - DEModulator, / A hardware device that converts digital computer data into analog tones that can be transmitted over dial up telephone circuits. / The expanded form of Modem would read as Modulator Demodulator. Modem is a device which regulates analog carrier signal to process digital information. The modem encodes digital information and decodes transmitted information. RS-232 is a standard interface that connects computers to external modems. Any external modem that is compatible to this interface can be attached to the computer. These modems could come on an expansion board which is known as internal modem. / abbreviation for modulator-demodulator. A device containing a modulator and a demodulator. The modulator converts a binary stream into a form suitable for transmission over an analog medium such as telephone wires or (in the case of a wireless modem) air. The demodulator performs the reverse operation, so two modems connected via an analog channel can be used to transfer binary data over the (analog) channel. |
