Compare centralized and pure peer-to-peer applications.What are the advantages and disadvantages of each approach?
What will be an ideal response?
A centralized P2P application uses a server that connects to each peer. Centralized
P2P applications exemplify the client/server relationship. It is easy to monitor and manage
user access with centralized P2P applications. One major weakness of the centralized
approach is the dependency on the server—if the server fails, the entire application also fails.
The server’s capabilities limit the application’s overall performance.A pure P2P application
does not have a server and therefore does not suffer from the same deficiencies as applications
that depend on servers. Pure peer-to-peer applications have disadvantages as well.Anyone
with the appropriate software can join the network of peers and often remain
anonymous—for this reason, determining who is on the network at any moment is difficult.
Also, the lack of a server hinders the protection of copyright and intellectual-property rights.
Real-time searches can be slow and increase network traffic, because every query must propagate
throughout the entire network.
