Multiplexing is the technology that is able to combine multiple communication signals together in order for them to traverse an otherwise single signal communication medium simultaneously. Multiplexing can be applied to both analog and digital signals.

What do u mean by multiplexing?

In telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. ... Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications.

What is the purpose of multiplexing in data communication?

Multiplexing Basics

The purpose of multiplexing is to enable signals to be transmitted more efficiently over a given communication channel, thereby decreasing transmission costs. A device called a multiplexer (often shortened to "mux") combines the input signals into one signal.
