If Shakespeare had created this word, what definition might he have invented? We shall never know as it was another great inventor who was around when muxing, or multiplexing, came into existence Alexander Graham Bell. Bell became interested in telecommunications when he began working on the possibility of transmitting multiple telegraph signals simultaneously over a single pair of wires using mechanical resonance to distinguish and separate the different signals. Today, muxing is commonplace in telecommunications and computer networks. It is the process of combining multiple analog message signals or digital data streams into one signal over a shared medium or communication channel. The purpose is to gain economies by sharing resources, such as transferring several phone calls over one wire or combining audio and video streaming. A reverse process, demultiplexing, can extract the original channels on the receiver side. And then there is inverse multiplexing (IMUX), which has the opposite purpose of multiplexing. IMUX breaks one data stream into several streams, transfers the streams simultaneously over several communication channels, and then recreates the original data stream. A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX).
