Communication is a process of transferring information from one entity to another. Communication processes are sign-mediated interactions between at least two agents which share a repertoire of signs and semiotic rules. Communication is commonly defined as "the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs". Although there is such a thing as one-way communication, communication can be perceived better as a two-way process in which there is an exchange and progression of thoughts, feelings or ideas (energy) towards a mutually accepted goal or direction (information).
Communication is a process whereby information is enclosed in a package and is channeled and imparted by a sender to a receiver via some medium. The receiver then decodes the message and gives the sender a feedback. All forms of communication require a sender, a message, and a receiver. Communication requires that all parties have an area of communicative commonality. There are auditory means, such as speech, song, and tone of voice, and there are nonverbal means, such as body language, sign language, paralanguage, touch, eye contact, and writing.
 Information communication revolutions
Over time, technology has progressed and has created new forms of and ideas about communication. These technological advances revolutionized the processes of communication. Researchers have divided how communication was transformed into three revolutionary stages:
In the 1st Information Communication Revolution, the first written communication began, with pictographs. These writings were made on stone, which were too heavy to transfer. During this era, written communication was not mobile, but nonetheless existed.
In the 2nd Information Communication Revolution, writing began to appear on paper, papyrus, clay, wax, etc. Common alphabets were introduced, allowing the uniformity of language across large distances. Much later the Gutenberg printing-press was invented. Gutenberg created the first printed book using his press, and that book was the Bible. The writings were able to be transferred for others across the world to view. Written communication is now storable, and portable.
In the 3rd Information Communication Revolution, information can now be transferred via controlled waves and electronic signals.
Communication is thus a process by which meaning is assigned and conveyed in an attempt to create shared understanding. This process requires a vast repertoire of skills in intrapersonal and interpersonal processing, listening, observing, speaking, questioning, analyzing, and evaluating. It is through communication that collaboration and cooperation occur.
There are also many common barriers to successful communication, two of which are message overload (when a person receives too many messages at the same time), and message complexity. Communication is a continuous process.
 Types of communication
Prof. Albert Mehrabian (UCLA, 1967) identified three major parts that convey meaning in human face to face communication: body language, voice tonality, and words. He conducted research to determine how people make meaning when a speaker says one thing but means another. If the speaker is sending a mixed message the listener will rely on the following cues to determine true meaning:
- 55% of impact is determined by body language—postures, gestures, and eye contact,
- 38% by the tone of voice, and
- 7% by the content or the words spoken.
Mehrabian says this only applies in situations where the speaker is talking about feelings or attitudes.
Although the exact percentage of influence may differ due to variables such as the perceptions or biases of the listener and the speaker, communication as a whole is meant to convey meaning and thus, in some cases, can be universal. A system of signals, such as voice sounds, intonations or pitch, gestures or written symbols can communicate thoughts or feelings. If a language employs communicating with signals, voice, sounds, gestures, or written symbols, can animal communications be considered to be a language? Animals do not have a written form of a language, but use a language to communicate with each another. In that sense, animal communication can be considered as a separate language.
Human spoken and written languages can be described as a system of symbols (sometimes known as lexemes) and the grammars (rules) by which the symbols are manipulated. The word "language" is also used to refer to common properties of languages. Language learning is normal in human childhood. Most human languages use patterns of sound or gesture for symbols which enable communication with others around them. There are thousands of human languages, and these seem to share certain properties, even though many shared properties have exceptions.
There is no defined line between a language and a dialect, but the linguist Max Weinreich is credited as saying that "a language is a dialect with an army and a navy". Constructed languages such as Esperanto, programming languages, and various mathematical formalisms are not necessarily restricted to the properties shared by human languages.
 Nonverbal communication
Nonverbal communication is the process of communicating through sending and receiving wordless messages. Such messages can be communicated through gesture, body language or posture; facial expression and eye contact, object communication such as clothing, hairstyles or even architecture, or symbols and infographics, as well as through an aggregate of the above, such as behavioral communication. Nonverbal communication plays a key role in every person's day to day life, from employment to romantic engagements.
Speech may also contain nonverbal elements known as paralanguage, including voice quality, emotion and speaking style, as well as prosodic features such as rhythm, intonation and stress. Likewise, written texts have nonverbal elements such as handwriting style, spatial arrangement of words, or the use of emoticons. A portmanteau of the English words emotion (or emote) and icon, an emoticon is a symbol or combination of symbols used to convey emotional content in written or message form.
Other communication channels such as telegraphy fit into this category, whereby signals travel from person to person by an alternative means. These signals can in themselves be representative of words, objects or merely be state projections. Trials have shown that humans can communicate directly in this way without body language, voice tonality or words.
Categories and Features G. W. Porter divides non-verbal communication into four broad categories:
Physical. This is the personal type of communication. It includes facial expressions, tone of voice, sense of touch, sense of smell, and body motions.
Aesthetic. This is the type of communication that takes place through creative expressions: playing instrumental music, dancing, painting and sculpturing.
Signs. This is the mechanical type of communication, which includes the use of signal flags, the 21-gun salute, horns, and sirens.
Symbolic. This is the type of communication that makes use of religious, status, or ego-building symbols.
Distance. The distance one stands from another frequently conveys a non-verbal message. In some cultures it is a sign of attraction, while in others it may reflect status or the intensity of the exchange.
Orientation. People may present themselves in various ways: face-to-face, side-to-side, or even back-to-back. For example, cooperating people are likely to sit side-by-side while competitors frequently face one another.
Posture. Obviously one can be lying down, seated, or standing. These are not the elements of posture that convey messages. Are we slouched or erect ? Are our legs crossed or our arms folded ? Such postures convey a degree of formality and the degree of relaxation in the communication exchange.
Physical Contact. Shaking hands, touching, holding, embracing, pushing, or patting on the back all convey messages. They reflect an element of intimacy or a feeling of (or lack of) attraction.
Facial Expressions. A smile, frown, raised eyebrow, yawn, and sneer all convey information. Facial expressions continually change during interaction and are monitored constantly by the recipient. There is evidence that the meaning of these expressions may be similar across cultures.
Gestures. One of the most frequently observed, but least understood, cues is a hand movement. Most people use hand movements regularly when talking. While some gestures (e.g., a clenched fist) have universal meanings, most of the others are individually learned and idiosyncratic.
Looking. A major feature of social communication is eye contact. It can convey emotion, signal when to talk or finish, or aversion. The frequency of contact may suggest either interest or boredom.
 Visual communication
Visual communication as the name suggests is communication through visual aid. It is the conveyance of ideas and information in forms that can be read or looked upon. Primarily associated with two dimensional images, it includes: signs, typography, drawing, graphic design, illustration, colour and electronic resources. It solely relies on vision. It is form of communication with visual effect. It explores the idea that a visual message with text has a greater power to inform, educate or persuade a person. It is communication by presenting information through visual form.
The evaluation of a good visual design is based on measuring comprehension by the audience, not on aesthetic or artistic preference. There are no universally agreed-upon principles of beauty and ugliness. There exists a variety of ways to present information visually, like gestures, body languages, video and TV. Here, focus is on the presentation of text, pictures, diagrams, photos, et cetera, integrated on a computer display. The term visual presentation is used to refer to the actual presentation of information. Recent research in the field has focused on web design and graphically oriented usability. Graphic designers use methods of visual communication in their professional practice.
 Understanding the Field of Communication
The field of communication is typically broken into three distinct camps: human communication, mass communications, and communication disorders 
- Interpersonal Communication
- Organizational Communication
- Oral Communication
- Small Group Communication
- Intercultural Communication
- Nonviolent Communication
- Public Speaking
Examples of Mass Communications include:
- Mass communication
- Graphic communication
- Science communication
- Strategic Communication
- Superluminal communication
- Technical communication
- Public relations
- Broadcast Media
Examples of Communication Disorders include:
 Oral Communication
Oral communication is a process whereby information is transferred from a sender to receiver usually by a verbal means but visual aid can support the process.. The receiver could be an individual person, a group of persons or even an audience. There are a few of oral communication types: discussion, speeches, presentations, etc. However, often when you communicate face to face the body language and your voice tonality has a bigger impact than the actual words that you are saying. According to research:
- 55% of the impact is determined by the body language. For example: posture, gesture, eye contact, etc.
- 38% by the tone of your voice
- 7% by the content of your words in a communication process.
You can notice that the content or the word that you are using is not the determining part of a good communication. The “how you say it” has a major impact on the receiver. You have to capture the attention of the audience and connect with them. For example, two persons saying the same joke, one of them could make the audience die laughing related to his good body language and tone of voice. However, the second person that has the exact same words could make the audience stare at one another.
In an oral communication, it is possible to have visual aid helping you to provide more precise information. Often enough, we use a presentation program in presentations related to our speech to facilitate or enhance the communication process. Although, we cannot communicate by providing only visual content because we would not be talking about oral communication anymore.
 Communication Modeling
The first major model for communication came in 1949 by Claude Shannon and Warren Weaver for Bell Laboratories  The original model was designed to mirror the functioning of radio and telephone technologies. Their initial model consisted of three primary parts: sender, channel, and receiver. The sender was the part of a telephone a person spoke into, the channel was the telephone itself, and the receiver was the part of the phone where one could hear the other person. Shannon and Weaver also recognized that often there is static that interferes with one listening to a telephone conversation, which they deemed noise.
In a simple model, often referred to as the transmission model or standard view of communication, information or content (e.g. a message in natural language) is sent in some form (as spoken language) from an emisor/ sender/ encoder to a destination/ receiver/ decoder. This common conception of communication simply views communication as a means of sending and receiving information. The strengths of this model are simplicity, generality, and quantifiability. Social scientists Claude Shannon and Warren Weaver structured this model based on the following elements:
- An information source, which produces a message.
- A transmitter, which encodes the message into signals
- A channel, to which signals are adapted for transmission
- A receiver, which 'decodes' (reconstructs) the message from the signal.
- A destination, where the message arrives.
Shannon and Weaver argued that there were three levels of problems for communication within this theory.
- The technical problem: how accurately can the message be transmitted?
- The semantic problem: how precisely is the meaning 'conveyed'?
- The effectiveness problem: how effectively does the received meaning affect behavior?
Daniel Chandler critiques the transmission model by stating
- It assumes communicators are isolated individuals.
- No allowance for differing purposes.
- No allowance for differing interpretations.
- No allowance for unequal power relations.
- No allowance for situational contexts.
In 1960, David Berlo expanded on Shannon and Weaver’s (1949) linear model of communication and created the SMCR Model of Communication . The Sender-Message-Channel-Receiver Model of communication separated the model into clear parts and has been expanded upon by other scholars.
Communication is usually described along a few major dimensions: Message (what type of things are communicated), source / emisor / sender / encoder (by whom), form (in which form), channel (through which medium), destination / receiver / target / decoder (to whom), and Receiver. Wilbur Schram (1954) also indicated that we should also examine the impact that a message has (both desired and undesired) on the target of the message . Between parties, communication includes acts that confer knowledge and experiences, give advice and commands, and ask questions. These acts may take many forms, in one of the various manners of communication. The form depends on the abilities of the group communicating. Together, communication content and form make messages that are sent towards a destination. The target can be oneself, another person or being, another entity (such as a corporation or group of beings).
- Syntactic (formal properties of signs and symbols),
- Pragmatic (concerned with the relations between signs/expressions and their users) and
- Semantic (study of relationships between signs and symbols and what they represent).
Therefore, communication is social interaction where at least two interacting agents share a common set of signs and a common set of semiotic rules. This commonly held rules in some sense ignores autocommunication, including intrapersonal communication via diaries or self-talk, both secondary phenomena that followed the primary acquisition of communicative competences within social interactions.
In light of these weaknesses, Barnlund (2008) proposed a transactional model of communication . The basic premise of the transactional model of communication is that individuals are simultaneously engaging in the sending and receiving of messages.
In a slightly more complex form a sender and a receiver are linked reciprocally. This second attitude of communication, referred to as the constitutive model or constructionist view, focuses on how an individual communicates as the determining factor of the way the message will be interpreted. Communication is viewed as a conduit; a passage in which information travels from one individual to another and this information becomes separate from the communication itself. A particular instance of communication is called a speech act. The sender's personal filters and the receiver's personal filters may vary depending upon different regional traditions, cultures, or gender; which may alter the intended meaning of message contents. In the presence of "communication noise" on the transmission channel (air, in this case), reception and decoding of content may be faulty, and thus the speech act may not achieve the desired effect. One problem with this encode-transmit-receive-decode model is that the processes of encoding and decoding imply that the sender and receiver each possess something that functions as a code book, and that these two code books are, at the very least, similar if not identical. Although something like code books is implied by the model, they are nowhere represented in the model, which creates many conceptual difficulties.
Theories of coregulation describe communication as a creative and dynamic continuous process, rather than a discrete exchange of information. Canadian media scholar Harold Innis had the theory that people use different types of media to communicate and which one they choose to use will offer different possibilities for the shape and durability of society (Wark, McKenzie 1997). His famous example of this is using ancient Egypt and looking at the ways they built themselves out of media with very different properties stone and papyrus. Papyrus is what he called 'Space Binding'. it made possible the transmission of written orders across space, empires and enables the waging of distant military campaigns and colonial administration. The other is stone and 'Time Binding', through the construction of temples and the pyramids can sustain their authority generation to generation, through this media they can change and shape communication in their society (Wark, McKenzie 1997).

 Nonhuman communication
Communication in many of its facets is not limited to humans, or even to primates. Every information exchange between living organisms — i.e. transmission of signals involving a living sender and receiver — can be considered a form of communication. Thus, there is the broad field of animal communication, which encompasses most of the issues in ethology. Also very primitive animals such as corals are competent to communicate. On a more basic level, there is cell signaling, cellular communication, and chemical communication between primitive organisms like bacteria, and within the plant and fungal kingdoms. All of these communication processes are sign-mediated interactions with a great variety of distinct coordinations.
Animal communication is any behaviour on the part of one animal that has an effect on the current or future behavior of another animal. Of course, human communication can be subsumed as a highly developed form of animal communication. The study of animal communication, called zoosemiotics' (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. This is quite evident as humans are able to communicate with animals, especially dolphins and other animals used in circuses. However, these animals have to learn a special means of communication. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, many prior understandings related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, have been revolutionized.
 Plants and fungi
Among plants, communication is observed within the plant organism, i.e. within plant cells and between plant cells, between plants of the same or related species, and between plants and non-plant organisms, especially in the rootzone. Plant roots communicate in parallel with rhizobia bacteria, with fungi and with insects in the soil. This parallel sign-mediated interactions which are governed by syntactic, pragmatic and semantic rules are possible because of the decentralized "nervous system" of plants. The original meaning of the word "neuron" in Greek is "vegetable fiber" and as recent research shows, most of the intraorganismic plant communication processes are neuronal-like. Plants also communicate via volatiles in the case of herbivory attack behavior to warn neighboring plants. In parallel they produce other volatiles which attract parasites which attack these herbivores. In Stress situations plants can overwrite the genetic code they inherited from their parents and revert to that of their grand- or great-grandparents.
Fungi communicate to coordinate and organize their own growth and development such as the formation of mycelia and fruiting bodies. Additionally fungi communicate with same and related species as well as with nonfungal organisms in a great variety of symbiotic interactions, especially with bacteria, unicellular eukaryotes, plants and insects. The used semiochemicals are of biotic origin and they trigger the fungal organism to react in a specific manner, in difference while to even the same chemical molecules are not being a part of biotic messages doesn’t trigger to react the fungal organism. It means, fungal organisms are competent to identify the difference of the same molecules being part of biotic messages or lack of these features. So far five different primary signalling molecules are known that serve to coordinate very different behavioral patterns such as filamentation, mating, growth, pathogenicity. Behavioral coordination and the production of such substances can only be achieved through interpretation processes: self or non-self, abiotic indicator, biotic message from similar, related, or non-related species, or even “noise”, i.e., similar molecules without biotic content-
 Communication as academic discipline
Communication as an academic discipline, sometimes called "communicology," relates to all the ways we communicate, so it embraces a large body of study and knowledge. The communication discipline includes both verbal and nonverbal messages. A body of scholarship all about communication is presented and explained in textbooks, electronic publications, and academic journals. In the journals, researchers report the results of studies that are the basis for an ever-expanding understanding of how we all communicate.
Communication happens at many levels (even for one single action), in many different ways, and for most beings, as well as certain machines. Several, if not all, fields of study dedicate a portion of attention to communication, so when speaking about communication it is very important to be sure about what aspects of communication one is speaking about. Definitions of communication range widely, some recognizing that animals can communicate with each other as well as human beings, and some are more narrow, only including human beings within the different parameters of human symbolic interaction.
