No, the modem and codec are not exactly the functional inverse of each other. teh modem converts the digital data to analog signal by teh modulating part of it. teh demodulating part of the modem can be used to covert teh ANALOG SIGNAL to digital data....but this analog signal will be modulated analog signal. the coding part of teh codec convert teh analog signals to teh digital signal .these analog signals are pure analog signals. Hence teh codec and modem may seem as functional inverses but do not work as so due to teh fact dat the demodulating part of the modem used only the modulated analog signal and cannot process the pure analog signals .
To send digital across an analog wire the signal is first laid on top of an analog signal. The process is called "modulation". It's the same thing that's done with television and radio, it's just a different type of signal.The modulated signal is sent across the wire and the MODEM at the other end receives the signal and decodes it.The process is called, "MOdulate, DEModulate, or more simply, MODEM.
The Full Form of Modem is : Modulator-demodulator. It is used to convert analog signals to digital signal and viceversa
Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...
A coder can accept any kind of analog signal while demodulator can only accept a modulated sine wave. Then they generate the digital signal.

modem means modulator demodulator. it converts digital signal to analog signal. it is use to transmit computer signal (digital signal) over the telephone line to communicate to other computers. modem converts the computer digital signal into frequency (analog signal) so that it can transmit over the telephone line and at the receiving end the modem converts the analog signal back to digital for the receiving computer to understand it.
A modem converts a digital signal into an analog signal. Allowing us to use a phone line as a transmission medium.
Modem is a what not a who. A computer modem is a device that uses an analog carrier signal to encode digital information. The modem is how you connect to dial up Internet.
The -dem part does. The mo- part goes the other way. "Modem" is an abbreviation for "modulator-demodulator".

Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
Modem in fact acts as an interpreter. When computer exchanges datas with other computers in internet,it has to take the assistance of telephone. But computer understands digital signal whereas telephone analog signal. For making reconciliation between the two requires one interpreter who can convert analog to digital and digital to analog. Modem's activity is to convert analog signal from telephone to digital understood by computer and vice verse.
modem Measuring usually the voltage of the analog signal many times a second in binary number code generates a digital signal, and using a binary number code to control the voltage of an output results in a reproduced analog signal. That is what is done for stuff like digital television. A Modem (prior answer) is for when the analog signals are used to connect digital computers (like yours) together, usually over a long distance.

a modem is a tool which can change analog sinal to digital signal and vice-versa. when the communication has to take place between the two computers then there is involvement of wires or some wireless technology. if communication exists between then it is through analog signals and computer can accept only digital signal. so,basically modem changes the analog signal to digital when the data is to be received at computer's end and hence it works and facilitates the commmunication between two or more computers.
Modem is attached in the broadband connection,acting as interpreter .It converts analog signal from telephone to digital,and computers' digital signal to telephone's analog. However,now a days, simply by inserting a pen drive into the computer, we get internet connection,without modem.
