What is P2P ?
Peer is a entity that has attributes similar to other entities in system P2P is a technology and not a protocol Process whereby computers trade information between each other without having to pass the information through a centrally controlled server Sharing of computer resources (information, processing) and services by direct exchange between systems

Definition
The term peer-to-peer computing refers to use a class of systems and applications that employ distributed resources to perform a function in a decentralized manner to compute
Models
Multiple Peer Relationship PCs are connected/networked to each other through servers, and files can be shared and collected from anyone else on that same network.
Models
Distributed Peer Relationship A group of computers connected together to combine their computing and processing abilities to search the Internet or solve very complex problems requiring massive process crunching
Models
Collaborative Peer Relationship A small group of people agree to collaborate through a common interface, such as on-line gaming, chat rooms, instant messaging, or e-learning environment
The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together (i.e., it supports multiple platforms). The .NET Framework (pronounced dot net) is a software framework that runs primarily on Microsoft Windows. It includes a large library and provides language interoperability (each language can use code written in other languages) across several programming languages.
