# Communication

Communication is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
The scientific study of communication can be divided into:
* Information theory - which studies the quantification, storage, and communication of information in general;
* Communication studies - which concerns human communication;
* Biosemiotics - which examines communication in and between living organisms in general.

## Types of communication

Communication can be categorized into various types based on different criteria. Here are some common types of communication:
* Verbal Communication: This involves the use of spoken or written words to convey messages. Verbal communication includes face-to-face conversations, phone calls, speeches, presentations, interviews, letters, emails, and other written documents.
* Nonverbal Communication: Nonverbal communication refers to the exchange of information without the use of words. It includes body language, facial expressions, gestures, posture, eye contact, tone of voice, touch, and the use of physical space.
* Visual Communication: Visual communication involves the use of visual elements to convey information, such as graphs, charts, diagrams, maps, photographs, videos, symbols, and illustrations. Visual communication is particularly effective for presenting complex data in a clear and concise manner.
* Written Communication: This type of communication involves the exchange of information through written words. Written communication includes emails, letters, memos, reports, manuals, newsletters, articles, and any other text-based documents.
* Interpersonal Communication: Interpersonal communication occurs between two or more people and involves the exchange of thoughts, feelings, and information. It encompasses face-to-face conversations, phone calls, video calls, and any other form of direct interaction between individuals.
* Group Communication: Group communication involves communication among members of a group or team. It can take place in various settings, such as meetings, brainstorming sessions, workshops, conferences, and group discussions.
* Mass Communication: Mass communication involves the transmission of messages to a large and diverse audience through mass media channels, such as television, radio, newspapers, magazines, websites, social media, and advertising.
* Digital Communication: Digital communication refers to the exchange of information using electronic devices and digital technologies. It includes emails, text messages, instant messaging, social media platforms, video conferencing, and other online communication tools.
* Formal Communication: Formal communication follows established rules, procedures, and protocols within organizations. It includes official announcements, reports, policies, procedures, and other communications that adhere to organizational hierarchies and structures.
* Informal Communication: Informal communication occurs spontaneously and without following formal channels. It includes casual conversations, gossip, rumors, social interactions, and other informal exchanges of information within organizations or social groups.
These types of communication can overlap and intersect in various ways, and effective communication often involves a combination of different methods depending on the context and purpose of the communication.
