FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A modem (abbreviated from MOdulation/DEModulation) is a translating device that can convert signals from digital to analog and back. A modem is a device that translates digital signals from a computer into analog form so that they can be transmitted over analog telephone lines.

Detailed explanation-2: -A modem also receives modulated signals and demodulates them, recovering the digital signal for use by the data equipment.

Detailed explanation-3: -Modem stands for Modulator-demodulator. It converts the analog signals from the transmission wires into digital signals which can be read by the computer devices (modulation). Then conversion of digital signal into analog and extracting out the useful information (demodulation) takes place.

Detailed explanation-4: -A modem (from modulator–demodulator) can perform both operations.

Detailed explanation-5: -The modem consists of two parts which are the modulator and the demodulator. The primary function of the modulator part of any modem is to convert all the digital signals received into analogue signals. The demodulator works just opposite the modulator as it converts all the analogue signals to digital signals.
