A Peer-to-Peer Network (P2P) is a type of computer network where each device, or "peer," can communicate directly with others without needing a central server. This means that every participant can share resources, such as files or internet connections, making it a decentralized system. P2P networks are commonly used for file sharing, allowing users to download and upload content directly from one another. One popular example of a P2P network is BitTorrent, which enables users to share large files efficiently. In this system, when you download a file, you also upload parts of it to other users, creating a collaborative environment. This approach can lead to faster downloads and reduced strain on any single server.
