Peer – To – Peer Networks

This support unstructured access to Network attached resources. Each device in a Peer-to-Peer Network can be a client or a Server. All devices in the Network are capable of accessing data, Software and Network resources directly
Benefit or Advantages of Peer-To-Peer Network
  • They are easy to implement and operate – they are literal more than a collection of client Computers that have a network Operating System that permits Peer-To-Peer resources sharing, therefore establishing a Peer-to-Peer Network requires only the procurement and installation of Network cards hub, Computer, wiring and an Operating System that permits this resources Access methodology
  • Inexpensive to Operate – they lack expensive sophisticated Server that requires administrative and climate conditioning
  • No staff training – each machine is under user primary care
  • Can be establish with familiar Operating System such windows 95, 98, NT, 2000, Vista and work group
  • No hierarchical independence
  • More fault tolerant
Disadvantages and Limitation of Peer-to-Peer
  • Security weakness – users maintain multiple password for each machine
  • Lack of central repository for sharing resources imposes a burden of filing information squarely on each user
  • Uncoordinated and inconsistence backup of data and Software
  • Decentralize responsibility for enforcing file naming convention and storage location. No centralized depository for shared information and therefore difficult to keep current with what information is stored where
  • Performance of any Computer suffers whenever remote users go out and share its resources
  • Availability of files and other resources that a given Peer – may host are only available as that cost
For small organization with limited information sharing
