Introduction
How a Modem Works
A modem is a computer peripheral that allows you to communicate with other computers via telephone lines. Because ordinary telephone lines cannot carry digital information, a modem changes the digital data from your computer into analog signals, which can be transmitted much like voice signals. In a similar manner, the modem receiving the call then changes the analog signals back into digital data that the receiving computer can understand. This shift of digital data into analog signals and back again allows two computers to “speak” with one another. Called modulation/demodulation, this transformation of data and signals is how the modem received its name.
