The half-duplex method of transmission allows signals to travel in both directions over a medium but in only one direction at a time. This is because the transmission medium can carry signals in both directions, but the devices on each end of the medium can only transmit or receive at a time, not both simultaneously. Full duplex allows for simultaneous transmission and reception by both devices, while simplex only allows communication in one direction. Multiplexing combines multiple signals onto a single medium.
