Editing Multiplexing (section)

==Other meanings==
In [[spectroscopy]] the term is used to indicate that the experiment is performed with a mixture of frequencies at once and their respective response unraveled afterward using the [[Fourier transform]] principle.

In [[computer programming]], it may refer to using a single in-memory resource (such as a file handle) to handle multiple external resources (such as on-disk files).<ref>{{cite web

Some electrical multiplexing techniques do not require a physical "[[multiplexer]]" device, they refer to a "[[keyboard matrix]]" or "[[Charlieplexing]]" design style:
* Multiplexing may refer to the design of a [[multiplexed display]] (non-multiplexed displays are immune to [[multiplexed display#"Break up"|break up]]).
* Multiplexing may refer to the design of a "switch matrix" (non-multiplexed buttons are immune to "phantom keys" and also immune to  [[Keyboard (computing)#Control processor|"phantom key blocking"]]).

In high-throughput [[DNA sequencing]], the term is used to indicate that some artificial sequences (often called ''barcodes'' or ''indexes'') have been added to link given sequence reads to a given sample, and thus allow for the sequencing of multiple samples in the same reaction.

In [[sociolinguistics]], multiplexity is used to describe the number of distinct connections between individuals who are part of a [[social network (sociolinguistics)|social network]]. A multiplex network is one in which members share a number of ties stemming from more than one social context, such as workmates, neighbors, or relatives.
