Message in its most general meaning is an object of communication. It is something which provides information; it can also be this information itself. Therefore, its meaning is dependent upon the context in which it is used; the term may apply to both the information and its form.
More precisely, in the communications science, a message is information which is sent from a source to a receiver. Some common definitions include:
- Any thought or idea expressed briefly in a plain or secret language, prepared in a form suitable for transmission by any means of communication.
- An arbitrary amount of information whose beginning and end are defined or implied.
- Record information, a stream of data expressed in plain or encrypted language (notation) and prepared in a format specified for intended transmission by a telecommunications system.
