Full form of MODEM

Answer 1

modulation and demodulation

Answer 2

Modulation Demodulation - A modem(modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from light emitting diodes to radio.

The most familiar example is a voice band modem that turns the digital data of a personal computer into modulated electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone lines and demodulated by another modem at the receiver side to recover the digital data.

Modems are generally classified by the amount of data they can send in a given time unit, normally measured in bits per second (bit/s, or bps). They can also be classified by the symbol rate measured in baud, the number of times the modem changes its signal state per second. For example, the ITU V.21 standard used audio frequency-shift keying, aka tones, to carry 300 bit/s using 300 baud, whereas the original ITU V.22 standard allowed 1,200 bit/s with 600 baud using phase shift keying.

Answer 3

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.
