Peer-to-Peer Paradigm - Coggle Diagram
Peer-to-Peer Paradigm
BitTorrent is a P2P protocol, designed by Bram Cohen, for
sharing a large file among a set of peers.
Instead of one peer allowing another peer to download the whole file, a group of peers takes part in the process to give all peers in the group a copy of the file.

P2P Networks

a) Centralized Networks
-
- The directory system: listing of the peers and what they offer: uses the clientserver paradigm, but the storing and downloading of the files are done using the peer-to-peer paradigm.
- In this type of network, a peer first registers itself with a central server. The peer then provides its IP address and a list of files it has to share.

The central servers are vulnerable to attack, and if all of them fail, the whole system goes down.
