Answer: What is communication, why do we communicate, how do we communicate, and to what end, are all questions we ask in the study of communication. At its most basic, communication is the exchange of information and meaning. We are constantly communicating, in a wide range of different contexts, such as with each other (interpersonal communication), with different cultural groups or subgroups (intercultural communication), or to large audiences (mass communication), just to name a few. However, to understand communication, we need to understand the place of communication in culture.
Culture as a term is widely used in academic as well as in daily speech and discourse, referring to different concepts and understandings. While the term originally stems from ancient Greek and Roman cultures it has various dimensions today built from the different needs and uses of each field, be it anthropology, sociology or communication studies. For communication studies, we might start by defining culture as a set of learned behaviours shared by a group of people through interaction.
Cultures are not fixed, monolithic entities, but are fluid, always changing and responding to pressures and influences, such as the changing experiences of its members, or interaction with other cultures. However, to its members, the artefacts and even the existence of cultural behaviours and schemas may seem invisible or unremarkable. A culture may even have within it certain subcultures which exist within the main cultural framework of a society, but share within it specific peculiarities or modalities that also set it apart from the mainstream. These subcultures may continue to exist for many years or only a short period of time. They may die out, or may become incorporated into the mainstream as part of this ongoing evolution of culture.
