Distinctive features of a P2P network include decentralized structure, where each participant (or node) can act as both a client and a server. This architecture enables direct sharing of resources, such as files or bandwidth, without relying on a central server. P2P networks facilitate efficient data distribution, enhancing resilience and scalability. They are commonly used in applications like file sharing and blockchain technologies, providing users with greater control and privacy but also raising concerns about security and copyright issues.
