What is simple data multiplexing in data transmission?

Simple data multiplexing in data transmission refers to the technique of combining multiple data streams into a single channel or medium to optimize the use of resources and improve efficiency. This process allows multiple signals to share the same transmission medium without interference, typically achieved through methods like time-division multiplexing (TDM) or frequency-division multiplexing (FDM). By doing so, it increases the overall capacity of the communication system and reduces the need for additional hardware.
