Advantages and Disadvantages of P2P

18 Feb

In my previous blog I explained what peer to peer networking is, so now I’d like to discuss some of the advantages and disadvantages associated with it.


  • One advantage which is highly beneficial for its users is that it’s very reliable. For example, the failure of one peer will not affect the functioning of other peers…whereas in a client-server network if the central server fails it will affect the whole network.
  • Also there’s no need for specialist staff such as network technicians or system administrators as every user has the freedom to choose which files (e.g music, video, etc) they want to share with other users. Basically every user is their own administrator.
  • P2P networking is also very easy to install and is relatively cheap in comparison to a client-server network.



  • One of the main disadvantages associated with P2P networking is that viruses can easily be transmitted. Therefore it’s each users responsibility to ensure maximum security to prevent such viruses entering the system.
  • People should also take into consideration that it’s very difficult to back up files as P2P is a decentralised system. It’s highly recommended that each computer have it’s own back up system.
  • P2P networking is generally only useful for those in small groups (e.g <10), where a high level of security is not necessary. On the contrary it would not be suitable for those in larger groups ( e.g a business network) as there’s a high risk of catching a virus.p2p_sharing

    Wouldn’t there be a similar chance of catching a virus in smaller groups as well as in larger groups?

      Yes, what I should’ve said was that in larger groups more people are sharing files, etc so there’s a higher risk of people being exposed to viruses therefore more people will be affected.
