MUX

A MUX, or multiplexer, is a device that selects one input signal from multiple inputs and forwards it to a single output line. Think of it as a switch that chooses which data source to send forward, based on control signals. This allows efficient management of multiple data streams using fewer wires or channels, which is essential in digital systems like computers and communication networks. Essentially, a MUX consolidates many inputs into one output, making data routing more streamlined and organized.
