Social media includes web-based and mobile based intechnologies which are used to turn communication into interactive dialogue among organizations, communities, and individuals.
Andreas Kaplan and Michael Haenlein define social media as “a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, and that allow the creation and exchange of user-generated content.”
Social media is ubiquitously accessible, and enabled by scalable communication techniques.
A social network is a social structure made up of a set of actors (such as individuals or organizations) and the dyadic ties between these actors.
The social network perspective provides a clear way of analyzing the structure of whole social entities.
The study of these structures uses methods of social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics.
