Answer:
Modem is an hybrid device, which is responsible for modulating and demodulating information. It is a transmission medium and also it is a hardware tool used for connecting to internet.
Step-by-step explanation:
What is modulation?, let us understand. The process of converting analog to digital signal is called modulation and demodulation is vice-versa. The computer connects internet classically using telephone wire.
The telephone wire understands only analog signal and a computer understands only digital signal. So Modem’s role is to take care of this aspect while connecting to the internet.
