Multiplexer (or mux) : is a device that selects one of several analog or digital input signals and forwards the selected input into a single line.

Multiplexing (muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.

Statistical multiplexing is a type of communication link sharing, very similar to dynamic bandwidth allocation (DBA).

In statistical multiplexing, a communication channel is divided into an arbitrary number of variable bitrate digital channels or data streams.
