A P2P network, or peer-to-peer network, is a type of computer network 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 decentralized and efficient. In a P2P network, each peer acts as both a client and a server, meaning they can send and receive data. This structure is commonly used in applications like file sharing and blockchain technology, where users can collaborate and exchange information seamlessly.
