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:

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.
Electronic encoding transforms a signal into a code optimized for transmission or storage, generally done with a codec.
Neural encoding is the way in which information is represented in neurons.
Memory encoding is the process of converting sensations into memories.
Encryption transforms information for secrecy.

 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]].)
