Multiplexing / Muxing
Multiplexing, also known as muxing, is a technique used in telecommunications and computer networks to combine multiple data streams into a single transmission medium. It allows for efficient utilization of the available bandwidth, enabling the transmission of multiple signals simultaneously.
There are several types of multiplexing techniques, including time-division multiplexing (TDM), frequency-division multiplexing (FDM), and wavelength-division multiplexing (WDM). TDM divides the transmission medium into time slots, where each signal is allocated a specific time interval. FDM, on the other hand, divides the bandwidth into different frequency ranges for each signal. WDM combines multiple optical signals of different wavelengths onto a single fiber optic cable.
Multiplexing plays a crucial role in various technologies, such as digital television, internet protocols, and telecommunications networks. It enables efficient data transmission, reduces costs, and optimizes network performance.
