Peer to Peer sharing:

Peer to peer is a type of architecture in which nodes are interconnected with each other and share resources with each other without the central controlling server.

P2p system allows us to construct such a distributed system or application in which all resources and data contributed by hosts over the network.

p2p system allows us to sharing of data at very large scale without the use of any server whose job is to manage the scaling it means that scaling o data can be done without server

P2p are used in file sharing, web caching and providing information to user.

Difference between P2P and client -server

Advantages of Peer-to-peer networking:

It is easy to install and so is the configuration of computers on this network,

All the resources and contents are shared by all the peers, unlike server-client architecture .

P2P is more reliable as central dependency is eliminated. Failure of one peer doesn’t affect the functioning of other peers. In case of Client –Server network, if server goes down whole network gets affected.

The over-all cost of building and maintaining this type of network is comparatively very less

:Disadvantages(drawbacks) of Peer to peer architecture

In this network, the whole system is decentralized thus it is difficult to administer. That is one person cannot determine the whole accessibility setting of whole network.

Security in this system is very less- viruses, spywares, trojans, etc malwares can easily transmitted over this P2P architecture.

Data recovery or backup is very difficult. Each computer should have its own back-up system.

Thank you
