At the time of modulation, the modem converts the digital signal of the computer into analog, which is transmitted over the phone line. The exact opposite happens during demodulation, when the modem receives the analog signal from the telephone line and converts it into the digital signal of the computer.

In general terms, modem is used to connect two computers with the help of a line. To use the Internet, it is very important to have a Modem with a computer and a phone line.
