A Peer-to-Peer Network (P2P) is a type of computer network 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 bandwidth, directly with one another without needing a central server. P2P networks are commonly used for file sharing, online gaming, and communication applications. In a P2P network, each peer connects to multiple other peers, creating a decentralized structure. This setup enhances reliability and efficiency, as the network can continue to function even if some peers go offline. Popular examples of P2P applications include BitTorrent for file sharing and Skype for voice communication.
