Social networks are online platforms or services that allow individuals to connect and interact with others who share similar interests, backgrounds, or activities. Users can create profiles, share content, send messages, and engage in various forms of communication with other users. Social networks have become increasingly popular and influential in recent years, shaping how people connect, share information, and participate in online communities. Researchers in this area study various aspects of social networks, including user behavior, network structure, information diffusion, and the impact of social media on society and culture. They use techniques from fields such as sociology, computer science, and communication studies to understand how social networks function and evolve over time.
