STORING AND INDEXING SPATIAL DATA IN P2P SYSTEMS ABSTRACT: The peer-to-peer (P2P) paradigm has become very popular for storing and sharing information in a totally decentralized manner. At first‚ research focused on P2P systems that host 1D data. Nowadays‚ the need for P2P applications with multidimensional data has emerged‚ motivating research on P2P systems that manage such data. The majority of the proposed techniques are based either on the distribution of centralized indexes or on

weaknesses‚ opportunities and threats. Napster’s strengths are its wide selection of music‚ its brand name‚ and its convenience. Napster’s weaknesses are its pricing and its inability to differentiate. Napster’s opportunities are the decline of illegal peer to peer file sharing and the market growth. Napster’s threats are its competition with ITunes and its inability to offer a faster download bandwidth. An S.W.O.T analysis will help Napster figure out how to first overcome its competition‚ guarantee its

Honeypot (Infected Honeypot). In this paper we propose a method to remove the infected Honeypot by constructing a peer-to-peer structured botnet which would detect the uninfected Honeypot and use it to detect botnets originally used by the attacker. Our simulation results show that our method is very effective and can detect the botnets that are intended to malign the network. Keywords: Peer-to-peer network‚ Botnet‚ Honeypot‚ Hijacking. 1.

The Pirate Bay Case Study 24 06 2009 Introduction The Internet has served as a medium for peers to share any kind of files‚ like pictures‚ videos‚ music‚ books‚ etc. However‚ in order for peers to be able to exchange files‚ a platform is needed. There are many platforms available that serve as a bridge technology so that peers can share files with other peers around the world. These platforms only serve as a connection devise and not as a piracy store. As a result of the existence of these

Will the network be peer to peer or server based? Server Based How many computers will be attached to the network? There will be 50 computers connected to each server which will make 5 groups at a total of 250. What kind of networking device is easiest to reconfigure? What kind offers the best access to the network medium’s bandwidth between pairs of devices? A Switch. A NIC (Network interface Card) Case Project 3-3 Will the network be peer to peer or server based?

Events are almost signaled by the occurrence of an interrupt or a trap‚ which caused either by an error or by a specific request from a user program that an OS service be performed .Dual-mode Operation allows OS to protect itself and other system components whereas Multimode Operation increasingly CPUs support multi-mode operations.
