Social Media

  A Social network is useful to study relationships between individuals, groups, organizations, or even entire societies. The term is used to describe a social structure determined by such interactions. The ties, links, or connections in the structure are called "nodes".
  Many kinds of relationships may form the "network" between the individuals. Such an approach is useful for modeling and explaining many social phenomena.
Precisely because many different types of relations, singular or in combination, form into a network configuration, network analytics are useful to a broad range of research enterprises. In social science, these fields of study include, but are not limited to anthropology, biology, communication studies, economics, geography, information science, organizational studies, social psychology, sociology, and sociolinguistics.
  Scholars in these and other areas have used the idea of "social network" for almost a century to express the term of relationships between members, from the local to the global scale.
