What is the difference between a 'multiplexer' (MUX) and a 'demultiplexer' (DEMUX)?
What is the difference between a 'multiplexer' (MUX) and a 'demultiplexer' (DEMUX)?
a)
A MUX stores data, while a DEMUX retrieves data.b)
A MUX combines multiple input signals into a single output, while a DEMUX takes a single input and distributes it to one of many outputs.c)
A MUX is an analog component, while a DEMUX is digital.d)
There is no functional difference; the terms are interchangeable.Explanation
Think of a MUX as a rotary switch that selects one of its several inputs to connect to its single output, based on a control signal. A DEMUX does the reverse, acting like a data distributor that connects its single input to one of its several outputs, also determined by a control signal.Related questions
