Peer-to-peer (P2P) refers to a decentralized model of network architecture where each participant, or "peer," has equal status and can act as both a client and a server. This contrasts with the traditional client-server model, where servers provide resources and clients request them. P2P networks are commonly used for file sharing, communication, and distributed computing.

In P2P networks, peers communicate directly with each other, often without the need for a central server. This decentralization can enhance resilience and scalability, as the network can continue to function even if some peers go offline. However, it also introduces challenges such as ensuring data integrity and managing network traffic.

P2P technology has been widely adopted in various applications, including file-sharing platforms like BitTorrent, which allows users to download and upload files simultaneously, reducing the load on individual servers. It is also used in communication tools like Skype, which enables direct peer-to-peer voice and video calls, bypassing traditional telephony infrastructure.

Additionally, P2P networks are utilized in distributed computing projects, such as SETI@home and Folding@home, where idle computing resources from multiple peers are harnessed to process complex data sets. This collaborative approach can significantly increase computational power and efficiency.

Despite its advantages, P2P technology faces challenges related to security, privacy, and legal issues. For instance, P2P networks can be exploited for illegal file sharing, and the decentralized nature of these networks can make it difficult to enforce regulations and monitor activities. As a result, ongoing research and development are focused on improving the security and efficiency of P2P systems while addressing these challenges.
