- Multiplexing and Demultiplexing are two fundamental operations in data communication.
- The Key Difference Between Multiplexing and Demultiplexing is that Multiplexing takes several inputs and gives a single output whereas Demultiplexing takes a single input and gives several outputs.

- Multiplexing and Demultiplexing both have different features and functionalities, here is a comparison of some key features between them.
| Multiplexing | Demultiplexing |
|---|---|
| Multiplexing is a method or technique in which more than one signal are combined into one signal | De-multiplexing is the reverse of multiplexing. In this method, a multiplexed signal is again decomposed into individual signals. |
| Known as Data Selector | Known as Data Distributor |
| Multiplexing has 2n input data lines | Demultiplexing has a single input line |
| Parallel to serial conversion is there | Serial to parallel conversion is there. |
| When we design multiplexer, we don’t need additional gates. | Additional gates are included when designing De-multiplexer |
| Works on many to one operational principle | Works on one to many operational principle |
