In telecommunications and
computer networks, multiplexing (known as Muxing) is a term
used to refer to a process where multiple analog message
signals or digital data streams are combined into one signal
over a shared medium. The ais is to share an expensive
resource. For Example, in telecommunications, several phone
calls may be transferred using one wire.
A device that performs the
multiplexing is called multiplexer (MUX), and a device that
performs the reverse process is called demultiplexer (DEMUX).
Inverse multiplexing (IMUX) has the opposite aim as
multiplexing, namely to break one data stream into several
streams, transfer them simultaneously over several
communication channels, and recreate the original data
