Is FDM is an example of parallel transmission?

Frequency Division Multiplexing (FDM) is not an example of parallel transmission; rather, it is a method of multiplexing that allows multiple signals to be transmitted simultaneously over a single communication channel by assigning each signal a different frequency. In FDM, each signal occupies a unique frequency band within the overall bandwidth, enabling concurrent transmission without interference. Parallel transmission, on the other hand, involves sending multiple bits simultaneously over multiple channels or wires.
