'''Encoding''' is the process of transforming information from one format into another. The opposite operation is called '''[[decoding]]'''.
There are a number of more specific meanings that apply in certain contexts:
*Encoding (in [[cognition]]) is a basic perceptual process of interpreting incoming stimuli; technically speaking, it is a complex, multi-stage process of converting relatively objective sensory input (e.g., light, sound) into subjectively meaningful experience.
*[[Character encoding]] is a code that pairs a set of natural language characters (such as an [[alphabet]] or [[syllabary]]) with a set of something else, such as numbers or electrical pulses.
*Text encoding uses a [[markup language]] to tag the structure and other features of a text to facilitate processing by computers. (See also [[Text Encoding Initiative]].)
*[[Semantics encoding]] of formal language A in formal language B is a method of representing all terms (e.g. programs or descriptions) of language A using language B.
*[[Encoder|Electronic encoding]] transforms a signal into a [[code]] optimized for [[Transmission (telecommunications)|transmission]] or [[data storage|storage]], generally done with a [[codec]].
*[[Neural encoding]] is the way in which information is represented in [[neurons]].
*[[Encoding (memory)|Memory encoding]] is the process of converting sensations into memories.
*[[Encryption]] transforms information for [[secrecy]].
