A peer-to-peer network (P2P) is a decentralized communication model where each computer, or node, can act as both a client and a server. This allows users to share resources directly without relying on a central server. Each participant can contribute or request files and data, resulting in efficient resource utilization. P2P networks enhance resilience, as there’s no single failure point, making them less susceptible to outages. Common applications include file-sharing networks, cryptocurrency platforms, and collaborative projects, where distributed resources foster an inclusive and participatory environment.
