A Peer-to-Peer (P2P) network is a decentralized system where computers (nodes) communicate directly with each other, rather than relying on a central server. Each participant in the network acts as both a client and a server, sharing resources such as files, computing power, or storage.

One common use case for P2P networks is file sharing and decentralized applications (dApps). Instead of downloading data from a single centralized server, users retrieve it from multiple nodes, making the system more resilient, scalable, and censorship-resistant. P2P technology powers blockchain networks, decentralized cloud storage, and even financial systems like cryptocurrencies.
