Peer-to-Peer Networking (P2P) is a decentralized communication model where each participant, or "peer," can act as both a client and a server. This means that users can share resources, such as files or internet connections, directly with one another without needing a central server. P2P networks are commonly used for file sharing, online gaming, and collaborative projects. In a P2P network, each peer maintains its own data and can connect with multiple peers simultaneously. This structure enhances efficiency and resilience, as the network can continue to function even if some peers go offline. Popular examples of P2P applications include BitTorrent and Skype.
