"In P2P search (a.k.a. distributed search), each individual connected to the network serves its local index as a source of search. Instead of having a central company and a central server, each participant of the network is a search repository. Since we are talking about web indexing and web searching, a user's internet cache might be their contrib...
"A P2P application is different from the traditional client/server model because it acts both as a client and a server. That is to say, while they are able to request information from other servers, they also have the ability to respond to requests for information from other clients, at the same time. Figure 1 shows the architecture of a P2P networ...
"A typical peer-to-peer application has the following key features: • Peer discovery. The application must be able to find other applications that are willing to share information. Historically, the application finds these peers by registering to a central server that maintains a list of all applications currently willing to share, and giving that ...

Peers share their local indexes (or specific fragments of local indexes) by posting meta-information into the P2P network. This meta-information contains compact statistics and quality-of-service information, and effectively forms a global directory. However, this directory is implemented in a comple...

Description. 1. From the Wikiversity: "Deleuze coined the term 'dividual' to explain the mechanisms of a 'control society', which he opposes to Foucaults 'disciplinary society' (a stage he says we have left). The basic premise is that the term individual means indivisible, the smallest unit which society can be reduced to.
There are two important aspects to the emergence of P2P in the economic sphere. On the one hand, as a format for peer production processes (called ‘Commons-based peer production' or CBPP by Yochai Benkler) [1] it is emerging as a 'third mode of production' based on the cooperation of autonomous agents.
