It comes from the term MOdulator DEModulator.
A modem converts a digital signal from a computer into an analog signal, so that can be transferred down a telephone line and then at the other end it is converted back into a digital signal so that it can be sent into the receiving computer. These two processes are known as modulation and demodulation.
A modem is a Modulator and Demodulator. It's like a bridge between computer and ordinary telephone lines. Telephone lines only accept analog signals but computers only accept digital (binary) signals so modems help link them.
The data is changed to represent 2 audio frequencies. These noises are superimposed onto a phone line audio. This is known as 'modulation'. The incoming signal of course has to be changed back again to binary data, this is known as 'demodulation'.
The word modem is shorted for "Modulator-demodulator" referring to it's original use.
Modem = MoDem = Modulator + Demodulator
Modem is the device that modulates digital signals from Internal Network into analog signals onto analog lines towards ISP & demodulates analog signals into digital signals for use in Internal Network.
Modulator - De-Modulator - Originally it referred to a device that converts digital signals from a computer into analog signals that could travel over ordinary phone lines. It is often used now to refer to any interface device that sits between the transmission and the computer network to encrypt or optimize data flow.

Modem is short for modulator-demodulator. To modulate means it converts data into sounds (or radio waves) that can be transmitted, and to demodulate means to get the data back from the sounds (or radio waves) after receiving. So this makes in an input/output device.
MOdulator-DEModulator, often used for connecting data signals from a computer to a telephone or other communication system.
(Mo)dulator (Dem)otulator
MODEM stands for 'Modulator-Demodulator'.
Modulator-Demodulator stands for modem
TAM stands for telephone answering machine.
"MODEM" stands for "modulate/demodulate" The modem changes digital signals into analog tones that can be sent across a telephone wire.
Did you mean "modem"- If it is modem it stands for MODULATOR/DEMODULATOR. In simple terms something that converts digital signal to analogue and back
Modem stands for MOdulate DEModulate it takes digital information from your computer and turns it into sound (the MOdulate portion) and turns sound into data (the DEMod part)
MODEM stands for modulator/demodulator. Outgoing it modulates a carrier wave with information and transmits this data on a wire or through the air. When it receives a modulated signal it demodulates the signal and separates out the information.
A modem is a serial port interface to a telephone line, allowing you to create dialup connections to other modem equipped computers. Often, a modem card includes a serial port interface, a COM port. The term modem has also become applicable to other interfaces, such as DSL modems and cable modems, though that usage is tenuous in some cases. Modem stands for Modulator/Demodulator.
A modem (which stands for Modulator-Demodulator) converts digital data from the computer to analog data compatible with the telephone system. The analog signal is converted back into digital data on the other end of the call.
You will need to buy a new modem that is designed for your DSL modem. This is due to the fact that the modem is designed to use the dsl signal opposed to the cable modem.
One who want to connect to the internet.
A modem (stands for modulator-demodulator) is a device that allows a computer to use a telephone line to communicate with other computers. The fastest modem is 56kbs (56,000 bytes per second). This is a limitation of the phone lines, not of hardware. Modems are rarely used because cable or DSL have replaced them because of speed.
