چکیده
This paper provides a brief introduction to peer-to-peer (P2P) systems. Basic definitions and characteristics of P2P systems are described in Section 1. A comparison of a two related paradigms: P2P and Grid computing is also given. Section 2 classifies P2P substrates into two categories: structured and unstructured. Description of each category along with some examples is provided. A wide range of distributed applications can leverage the P2P paradigm, some of them have actually been deployed. Section 3 samples some of these applications.
