The other answers are correct in terms of the function of a mux or demux. Analog versions of these are made by companies such as Analog Devices and Maxim. Muxes for analog are commonly 2:1 (2 inputs, 1 output) with four of these commonly in one chip. There are also 4:1, 8:1, and 16:1 muxes available. See the links below.
Demultiplexers in analog terms will result in routing a single incoming analog signal to various outputs. This function can be addressed by the crosspoint switches or by arranging several analog switches in parallel and selecting the one you wish the output to appear at.

A multiplexer is a digital switch. For example a 4:1 mux has inputs A0, A1, A2, A3 and a SELECT. Based on the SELECT the output will equal one of the inputs.
An analog multiplexer would still be a switch.

A multiplexer is a box having many inputs but one output.
Which of its inputs is routed to the output can be selected by the user by selecting the switches.
In general, the inputs are 2^n and there are n selection switches.
A demux is the exact opposite with one input and many outputs and the input can be routed to the selected output by switch selection.
An analog mux/demux is the same. Just that it manages analog signals instead of square waves.

• A multiplexer, selects one at an instance from a number of input signals. A multiplexer has multiple signal inputs, one control input, and one output. It’s a many input single output device. • A demultiplexer, is just reverse of multiplexer which splits up multiplexed signal into several streams. It’s a many output single input device. • Encoders encode signal in one form into another. Decoders do just the opposite. • These two maybe single input single output(for serial signal stream) , many input many output(depending on code). Associated also are parallel to serial and serial to parallel converters, with many input-single output and single input-many output respectively. • All these six devices are used in digital processing, telecommunications, instrumentation and computer architechture etc. And in a perticular complete system they appear in pairs , like complex conjugates in maths. •
