Chapter 1: Introduction to Social Networks

 


1.1 Introduction to Social Networks

Online social networks are digital platforms that enable individuals to establish connections based on shared interests, values, or group memberships, such as friends, professional colleagues, or communities. These platforms provide a convenient medium for users to find, interact with, and communicate with others, using the web as the primary interface.

The development of a social network typically depends on users gradually expanding their personal connections. Through this process, individuals are introduced to new contacts and, on many platforms, can also be discovered by others. Many social networking platforms include features such as contact recommendations and suggestions for potential connections, which support the continuous growth of a user’s network.

Figure 1.1 illustrates the connections between contacts, showing how a user can discover friends of friends and receive friend recommendations based on mutual contacts. Such features facilitate network expansion, the establishment of new relationships, and reconnection with individuals who may have been previously lost from the user’s network.

Social networks generally serve two primary functions:

  • Connecting users and building personal or professional networks.

  • Providing a collaborative environment where users can contribute and share information.

Later in this chapter, the features of existing social networks are examined to identify essential elements for inclusion in the development of a custom network, as well as additional features that could enhance user experience.
