What is Modulation and Demodulation in Networking?


🔁 Modulation


  • It is the process of converting digital data into analog signals so it can be transmitted over analog media (like telephone lines or radio waves).


🔁 Demodulation


  • The reverse process — converting analog signals back into digital data at the receiving end.

These two processes are combined in a device called a Modem:

Modem = Modulator + Demodulator
