Social Network Theory is a framework for understanding how individuals and organizations are connected to one another through various social networks. Social Network Theory comprises several components that provide a comprehensive understanding of how these networks work. In this article, we will discuss the components of Social Network Theory in detail.

Nodes: Nodes are the fundamental building blocks of any social network. A node represents an individual, group, or organization that is part of the network. Each node has its unique properties, such as age, gender, education level, and interests.

Edges: Edges represent the relationships between nodes. These relationships could be personal or professional and can be represented in different ways such as communication channels, collaboration on projects, or shared hobbies.

Ties: Ties are the connections between nodes that create a bond between them. Ties can be strong or weak depending on the level of interaction and trust between nodes.

Social Capital:

Social capital refers to the value derived from being connected to other individuals or groups within a network. Social capital can lead to better access to resources and opportunities through increased information sharing and collaboration.


Density refers to the number of ties within a social network. High-density networks have many connections between nodes while low-density networks have fewer connections. The density of a network affects its overall stability and resilience.


Cohesion refers to the degree to which nodes within a network are connected to each other directly or indirectly. High cohesion results in strong ties between nodes while low cohesion results in weaker ties.


Centrality measures the importance of a node within a social network based on its position and influence. Highly central nodes have more connections and exert more influence over others within the network.

Structural Holes:

Structural holes refer to gaps between nodes or groups within a social network. These gaps can lead to opportunities for new connections and information flow, or they can act as barriers if left unaddressed.

In conclusion, Social Network Theory provides a comprehensive framework for understanding how individuals and organizations are connected through various social networks. Understanding the components of Social Network Theory can help in analyzing and predicting the behavior of individuals and groups within these networks and help to identify opportunities for growth and development.
