Communication is "an apparent answer to the painful divisions between self and other, private and public, and inner thought and outer world." As this definition indicates, communication is difficult to define in a consistent manner, because in common use it refers to a very wide range of different behaviors involved in the propagation of information. John Peters argues the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study.
SOAP is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks. It uses XML Information Set for its message format, and relies on application layer protocols, most often Hypertext Transfer Protocol (HTTP), although some legacy systems communicate over Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission.
A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used to convey an information signal, for example a digital bit stream, from one or several senders to one or several receivers. A channel has a certain capacity for transmitting information, often measured by its bandwidth in Hz or its data rate in bits per second.
Intrapersonal communication is the process by which an individual communicates within themselves, acting as both sender and receiver of messages, and encompasses the use of unspoken words to consciously engage in self-talk and inner speech.
Within the realm of communication studies, organizational communication is a field of study surrounding all areas of communication and information flow that contribute to the functioning of an organization. The flow of communication encompasses internal and external stakeholders and can be either formal or informal.
Two-way communication is a form of transmission in which both parties involved transmit information. Two-way communication has also been referred to as interpersonal communication. Common forms of two-way communication are:
Paul Watzlawick was an Austrian-American family therapist, psychologist, communication theorist, and philosopher. A theoretician in communication theory and radical constructivism, he commented in the fields of family therapy and general psychotherapy. Watzlawick believed that people create their own suffering in the very act of trying to fix their emotional problems. He was one of the most influential figures at the Mental Research Institute and lived and worked in Palo Alto, California.
In computer science, message passing is a technique for invoking behavior on a computer. The invoking program sends a message to a process and relies on that process and its supporting infrastructure to then select and run some appropriate code. Message passing differs from conventional programming where a process, subroutine, or function is directly invoked by name. Message passing is key to some models of concurrency and object-oriented programming.
Decoding, in semiotics, is the process of interpreting a message sent by an addresser (sender) to an addressee (receiver). The complementary process – creating a message for transmission to an addressee – is called encoding.
Friedemann Schulz von Thun is a German psychologist and expert in interpersonal communication and intrapersonal communication. Schulz von Thun worked as a professor of psychology at the University of Hamburg until his retirement on 30 Sep. 2009. Among his various publications is a three-part book series titled "Miteinander Reden" which has become a standard textbook series in Germany and is widely taught in schools, universities, and vocational skills training. Schulz von Thun developed a number of comprehensive theoretical models to help people understand the determinants and processes of inter-personal exchange and their embeddedness in the individual inner states and the outward situation. He invented the four sides model and developed a widely used visualization of the virtue square.
Interpersonal deception theory (IDT) is one of a number of theories that attempts to explain how individuals handle actual deception at the conscious or subconscious level while engaged in face-to-face communication. The theory was put forth by David Buller and Judee Burgoon in 1996 to explore this idea that deception is an engaging process between receiver and deceiver. IDT assumes that communication is not static; it is influenced by personal goals and the meaning of the interaction as it unfolds. The sender's overt communications are affected by the overt and covert communications of the receiver, and vice versa. IDT explores the interrelation between the sender's communicative meaning and the receiver's thoughts and behavior in deceptive exchanges.
The Encoding/decoding model of communication was first developed by cultural studies scholar Stuart Hall in 1973. Titled 'Encoding and Decoding in the Television Discourse', Hall's essay offers a theoretical approach of how media messages are produced, disseminated, and interpreted. Hall proposed that audience members can play an active role in decoding messages as they rely on their own social contexts, and might be capable of changing messages themselves through collective action.
Social information processing theory, also known as SIP, is an interpersonal communication theory and media studies theory developed in 1992 by Joseph Walther. Social information processing theory explains online interpersonal communication without nonverbal cues and how people develop and manage relationships in a computer-mediated environment. Walther argued that online interpersonal relationships may demonstrate the same or even greater relational dimensions and qualities (intimacy) as traditional FtF relationships. However, due to the limited channel and information, it may take longer to achieve than FtF relationships. These online relationships may help facilitate interactions that would not have occurred face-to-face due to factors such as geography and intergroup anxiety.
The hyperpersonal model is a model of interpersonal communication that suggests computer-mediated communication (CMC) can become hyperpersonal because it "exceeds [face-to-face] interaction", thus affording message senders a host of communicative advantages over traditional face-to-face (FtF) interaction. The hyperpersonal model demonstrates how individuals communicate uniquely, while representing themselves to others, how others interpret them, and how the interactions create a reciprocal spiral of FtF communication. Compared to ordinary FtF situations, a hyperpersonal message sender has a greater ability to strategically develop and edit self-presentation, enabling a selective and optimized presentation of one's self to others.
In interpersonal communication, an I-message or I-statement is an assertion about the feelings, beliefs, values, etc. of the person speaking, generally expressed as a sentence beginning with the word "I", and is contrasted with a "you-message" or "you-statement", which often begins with the word "you" and focuses on the person spoken to. Thomas Gordon coined the term "I message" in the 1960s while doing play therapy with children. He added the concept to his book for parents, P.E.T.: Parent Effectiveness Training (1970). Not every message that begins with the word "I" is an I-message.
Active Audience Theory argues that media audiences do not just receive information passively but are actively involved, often unconsciously, in making sense of the message within their personal and social contexts. Decoding of a media message may therefore be influenced by such things as family background, beliefs, values, culture, interests, education and experiences. Decoding of a message means how well a person is able to effectively receive and understand a message. Active Audience Theory is particularly associated with mass-media usage and is a branch of Stuart Hall's Encoding and Decoding Model.
Roman Jakobson defined six functions of language, according to which an effective act of verbal communication can be described. Each of the functions has an associated factor. For this work, Jakobson was influenced by Karl Bühler's organon model, to which he added the poetic, phatic and metalingual functions.
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.
Models of communication are conceptual models used to explain the human communication process. The first major model for communication was developed in 1948 by Claude Shannon and published with an introduction by Warren Weaver for Bell Laboratories. It is also important to note Lasswell's model of communication, which was also developed in 1948 by Harold Lasswell. Following the basic concept, communication is the process of sending and receiving messages or transferring information from one part (sender) to another (receiver).
The sender-message-channel-receiver (SMCR) model of communication is an expansion of the Shannon-Weaver model of communication. David Berlo created this model, which separated Shannon and Weaver's linear model into clear parts, in 1960. It has been expanded upon by other scholars. Berlo described factors affecting the individual components in the communication making the communication more efficient.
