A P2P Network (Peer-to-Peer Network) is a decentralized communication model where each participant, or "peer," can connect directly with others without needing a central server. This allows users to share resources, such as files or bandwidth, directly with one another, making the network more efficient and resilient. In a P2P network, every peer acts as both a client and a server, enabling them to send and receive data. Popular applications of P2P networks include file-sharing services like BitTorrent and Napster, which allow users to download and upload files directly from each other’s devices.
