Communication

Communication is the process of exchanging information, usually via a common protocol. "Communication studies" is the academic discipline focused on communication forms, processes and meanings, including speech, interpersonal and organizational communication.

Humans communicate in order to share knowledge and experiences, give or receive orders, or cooperate. Common forms of human communication include sign language, speaking, writing, gestures, and broadcasting. Communication can be interactive, transactive, intentional, or unintentional; it can also be verbal or nonverbal. Communication varies considerably in form and style when considering scale. Internal communication, within oneself, is intrapersonal while communication between two individuals is interpersonal. At larger scales of communication both the system of communication and media of communication change. Small group communication takes place in settings of between three and 12 individuals creating a different set of interactions than large groups such as organizational communication in settings like companies or communities. At the largest scales mass communication describes communication to huge numbers of individuals through mass media. Communication also has a time component, being either synchronous or asynchronous.
