Disadvantages of Peer to Peer Network Architecture?

              Virus is the most challenge in the network side because in peer to peer architecture there are lot of viruses in the form of peer top peer programs.normally viruses are downloaded in the as a any application file like audio or video.Lot of copyrighted contents also shared by this technology along word wide.

            All the computers in this network will be act as server/client.So by one user cannot control whole network.Each computers are shared their own data.so it can be managed through that PC only.

            Data backup possible only in local computer side.so each computer should have its own storage for storing data.

            This network is only suitable for small network  may contain lass then 10 computers because its lack of security.However it low cost still it is not recommended for any commerical use where some sensitive data can be shared.

            In this decentralised architecture it is very difficult to find reliable computers.There is no assurance whether we are getting reliable data or not.Whether we are communicating with reliable computer or not.
