Not correct. Modem is a kind of computer hardware, which can translate computer digital signals into analog signals that can be transmitted along ordinary telephone lines. These analog signals can be received by another modem at the other end of the line and translated into a language that the computer can understand. The function of modem is to convert digital signal into analog signal and transmit it on telephone line. The function of modem is to shape and amplify the signal incorrectly. Using a modem, audio signals can be converted into higher frequency signals and higher frequency signals can be converted into audio signals. Another purpose of modulation is to promote line reuse to improve line utilization.
