Network science is the study of complex networks formed by interconnected elements. These networks can represent various systems, such as social relationships, biological systems, or computer networks. Researchers analyze the structure and behavior of these networks to understand how they function and how information or influence spreads within them. By using mathematical and computational tools, network science helps identify patterns and key components within networks. This field has applications in diverse areas, including epidemiology, social media, and transportation systems. Understanding networks can lead to improved strategies for managing resources, enhancing communication, and predicting outcomes in various domains.
