What is a Modem

A Modem (also called Modulator-Demodulator) is an electronic device which is used to link a user’s home network to the Internet. This link is established with the help of Internet Service Provider (ISP). It actually acts as a bridge between Computer and telephone lines. It converts signals and is also known as a device that allows communication. Modems convert analog data into digital data and also perform the reverse so it can be transmitted. Analog Data is transmitted over phone lines and Digital data is read by the computers. This means that the modem translates computer data into the language used by telephones and then reverses the process to translate the responding data back into computer language. View More...
