What is Social Network?

A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures.

The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics. Social networks and the analysis of them is an inherently interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory.

In the 1970s, the idea of computer networking was initially envisioned in the heyday of The Beatles as a military-centric command and control scheme. But as it expanded beyond than just a privileged few hubs, the idea that connected computers make a great forum for discussing mutual topics of interest, and perhaps even meeting or renewing acquaintances with other humans
