Peer-to-peer (P2P) is a decentralized network model where participants, known as peers, share resources directly with each other without relying on a central server. This means that each peer can act as both a client and a server, allowing for efficient data sharing and communication. P2P networks are commonly used for file sharing, online gaming, and cryptocurrency transactions. In a P2P system, users can connect and interact directly, which can enhance privacy and reduce costs. Popular examples of P2P technology include BitTorrent for file sharing and Bitcoin for digital currency transactions. This model promotes collaboration and resource sharing among users.
