This document discusses peer-to-peer networking and was prepared by four students under the supervision of Mr. Ababakr Ibarhim. It defines peer-to-peer networking as a network with no dedicated servers where all workstations are considered equal and can act as clients or servers. The key differences between peer-to-peer and client-server networks are described. Peer-to-peer networks have no centralized data storage and nodes can request and provide services. Examples of applications include file sharing, messaging, and collaboration. Advantages include low cost and efficient use of resources while disadvantages include lack of administration and security issues.

3. What is the Network ?
A network consists of two or more computers that are linked in order
to share resources (such as printers and CDs), exchange files, or allow
electronic communications. The computers on a network may be
linked through cables, telephone lines, radio waves, satellites.

4. Peer-to-Peer Networking
A Peer to Peer network has no dedicated Servers. Here in Peer to Peer network,
a number of workstations (or clients) are connected together for the purpose of
sharing devices, information or data. All the workstations are considered as
equal. Any one computer can act as client or server at any instance. This network
is ideal for small networks where there is no need for dedicated servers, like
home networks, small business networks, or retail shops. The Microsoft term for
Peer to Peer network is Workgroup.

6. Client-Server
The Client-Server network model is widely used network
model. Here, Server is a powerful system that stores the data
or information in it. On the other hands, the Client is the
machine which let the users access the data on the remote
server.

COMAPAISON
CLIENT-SERVER PEER-TO-PEER
Basic
Service
Data
Server
Expense
1.There is a specific server and specific clients
connected to the server.
1.Clients and server are not distinguished, each
node act as client and server.
2.The client request for service and
server respond with the service.
2.Each node can request for services and can also
provide the services.
3.The data is stored in a centralized
server.
3.Each peer has its own data.
4.When several clients request for the services
simultaneously, a server can get bottlenecked.
4.As the services are provided by several servers
distributed in the peer-to-peer system, a server
in not bottlenecked.
5.The client-server are expensive to
implement.
5.Peer-to-peer are less expensive to
implement.

10. P2P Networking - Architecture
• All nodes are both clients and servers
 Provide and consume data
 Any node can initiate a connection
• No centralized data source

11. P2P Network Characteristics
• Clients are also servers and routers
 P2P systems share resources, storage, files.
 Nodes are autonomous (no administrative authority)
• Its data is flowing one side.
• It does not need any central repository for managing their content
because all nodes in P2P network are autonomous in nature.
• Nodes have widely varying capabilities

12. P2P Networking – Applications
There are various areas where to use P2P network, such as –
• File sharing
• Instant messaging
• Voice Communication
• Collaboration
• High Performance Computing
• Others

13. P2PAdvantages
• Easy to set up
• Less Complexity
• Lower cost since network devices and dedicated servers may not be required
• Can be used for simple tasks such as transferring files and sharing printers
• Efficient use of resources
 Unused bandwidth, storage, processing power at the edge of the network
• Reliability
 Replicas
 Geographic distribution
 No single point of failure

14. P2P Disadvantages
 No centralized administration
 Not scalable
 Data recovery or backup is very difficult. Each computer should have its
own back-up system
 Security in this system is very less viruses, spywares, trojans, etc.
malwares can easily transmit over this P-2-P architecture.

15. What can we share on our network?
Profile is designed for users in a network environment as well as those on stand-
alone workstations. On a network you may choose any or all of these options:
• Share the same ProFile program loaded on a network drive,
• Share a single database to manage and query client files stored anywhere on the
network.
• Share a server folder for storing all client data files in one location,
• Share common option settings between all or some users,
