In Computer Science
There are two main senses of the word "message" in computer science: messages passed within software, which may or may not be human-readable, and human-readable messages delivered via computer software for person-to-person communication.
- Message passing is a form of communication used in concurrent and parallel computing, object-oriented programming, and interprocess communication, where communication is made by sending messages to recipients. In a related use of this sense of a message, in object-oriented programming languages such as Smalltalk or Java, a message is sent to an object, specifying a request for action.
- Instant messaging and e-mail are examples of computer software designed for delivering human-readable messages in formatted or unformatted text, from one person to another.

Famous quotes containing the words computer and/or science:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“If science ever gets to the bottom of Voodoo in Haiti and Africa, it will be found that some important medical secrets, still unknown to medical science, give it its power, rather than the gestures of ceremony.”
—Zora Neale Hurston (1891–1960)
