P2P Networking, or Peer-to-Peer Networking, is a decentralized communication model where each participant, or "peer," can act as both a client and a server. This means that users can share resources, such as files or bandwidth, directly with one another without needing a central server. This approach enhances efficiency and reduces costs, as it allows for direct connections between users. In P2P Networking, data is often distributed across multiple peers, making it more resilient to failures. Popular applications of this technology include file-sharing services like BitTorrent and communication platforms like Skype. These systems leverage the collective power of users to improve performance and accessibility.
