Carries multiple signal on a signal medium.
With advanced systems and more electronic features being added to modern cars, the need arises for a more reliable way to interconnect them. Instead of adding more wiring and more connections that may pose a reliability issue and add cost to the vehicle,manufactures can take advantage of multiplexing technology and send multiple sensor signals over fewer wires. Instead of adding more wiring, multiple sensors will send data to the vehicles computer over the same wire. Modern vehicles also incorperate networking technology where the vehicles computers may share information from a single sensor and use that information to perform a different task. For example a vehicles power train control module may use the input from a vehicle speed sensor to display the vehicles speed on the instrument panel. The powertrain control module may then share the vehicle speed information with the body controller to activate the door locks when the vehicle reaches a certain speed.
Multiplexing is used to condense information.
For instance, if you had four different telephone lines with their own numbers in a building but only had one pair of telephone wires to the building, you could connect all four telephones to a multiplexer and connect the multiplexer to the single line coming into the building.
On the other end of the single telephone line (at the phone switching station, for instance) you would connect a demultiplexer which would decode the information and send it to four individual phone lines.
Furthermore, any or all four lines could be used at the same time without bothering the other lines.

application of multiplexing in data communication
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
Downward multiplexing refers to distributing a single signal across multiple channels.
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
multiplexing refeers to the transmission of different signals in the same channel simultaneously. There are many forms of multiplexing that can be used, including frequency division multiplexing(FDM) where individual signals are transmitted over adjacent , non overlapping frequency bands. they are transmitted in parallel and simultaneously in time. In time division multiplexing(TDM) each signal is allowd to use the whole bandwidth for a certain period of time. Multiplexing is needed so that the available channel can be used efficiently and also to save costs. There is too much to know about multiplexing, here is just a short overview. One thing that one has to know is multiple access.
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including: TDM - examples: TDMA, T-carrier FDM - examples: DWDM Spatial - example: MIMO Code division - examples: CDMA Phase or polarization division - cable/satellite TV Statistcal - examples: packet mode (STS), FHSS etc etc. This is far from a complete list. I think the question needs to be more specific.
