Peer-to-peer systems improve connectivity in technology by allowing devices to communicate directly without requiring a centralized server. This decentralized model facilitates resource sharing, such as files or processing power, among users. Notable examples include BitTorrent for file sharing and various blockchain technologies. By distributing the workload across multiple nodes, peer-to-peer networks enhance performance and resilience, making it difficult for any single point of failure to disrupt the system. This approach also fosters greater collaboration and connection among users, promoting the sharing of information and resources.
