A P2P Protocol, or Peer-to-Peer Protocol, is a method of communication that allows computers to connect directly with each other without needing a central server. This decentralized approach enables users to share files, resources, or information directly, making it efficient and often faster than traditional client-server models. Commonly used in applications like BitTorrent and Skype, P2P protocols facilitate the exchange of data among multiple users simultaneously. Each participant, or "peer," can act as both a client and a server, contributing to the network's overall functionality and resilience.
