hi everyone,
i want to ask a very basic question? who performs modulation and demodulation? NIC(network interface card) or modem(provided by ISP)? Modulation and demodulation is necessary because the information which we want to send primarily consists of 1's and 0's which cant be traveled as it is on transmission medium such as cat5 cable. so it is nic which connects to home router by a cable. so if it is, then nic should have performed some kind of conversion so that information can be traveled.
please make my concept clear, i'm very much confused.
Thanks in advance
