Abstract: In Peer – to – Peer (P2P) computing technology, several individual systems are grouped together and are characterized by direct access between peer systems for exchanging services without any centralized server. Unlike traditional client-server model, in Peer – to – Peer each peer can act as client as well as server based on its requirements and each peer has its own capacity & responsibility (as client it can raise requests for services and as server it can serve requests coming from other peers). With the availability of internet, distinct systems at distinct locations are being connected easily which enhanced the usage of P2P applications. In this paper, we present the overview of various P2P architectures, characteristics of P2P in addition to its applications and challenges.
