Multiplexing allows several signals to share a single transmission medium by dividing it into multiple channels (in time, frequency, or code). Because multiple data streams can be carried over the same link, you can achieve simultaneous transmission and reception of data on that channel when paired with a suitable bidirectional path.

Simplex is one-way communication, so it cannot support two-way data flow. Broadcast is one-to-many and not about bidirectional capacity. Duplex refers to two-way communication, but without multiplexing it doesn’t inherently describe carrying multiple signals over the same medium. Multiplexing, by its nature, enables multiple streams to be transmitted together, which is why it’s the best fit for simultaneous data transmission and reception on a single link.
