Community structures

Community structures refer to groups within a larger network where members are more closely connected to each other than to those outside the group. In social terms, it's like friend groups within a school or neighborhood. In networks such as social media, biological systems, or transportation, these communities help organize the overall structure, making it easier to analyze how information, influence, or resources flow. Recognizing these groups helps us understand the network's organization and function by highlighting natural subdivisions where interactions are more frequent or meaningful.
