Eli5 What’s mux switch in computers
In: 0
A multiplexer is really very simple at its basic level. The most basic mux has three inputs and one output. One input acts as a switch to control which of the other two inputs is sent to the output. So say if the switch is 0 then the output=input 0, and if the switch is 1 output=input 1. This is a 2:1 mux. You can then scale this up to an nxm sized mux and even add other signal processing to make it more advanced.
