Peer to Peer and Client Server Model

Client Server Model
Client Server model is a Networking Technique in which one of two roles are assigned  to the computers in a network: Client or server.server is a computer system that selectively shares its resources and provide services to its clients; client is a computer that make use of a resources with the help of server. Some features of this model are:
1)There will be atleast one Server and any no. of clients.
2)Server Provides services to clients.eg. if client 1 wants to access internet,then it will make request to server.server will check its rights and will provide access to internet as per rights assigned.Similarly if anybody wants to communicate with client 1 ,then it will authorized by server to gain access.
3)There is centralized controlling hub hence more security and rights assignment can be implemented.
4)Failure of Server will fail the entire network.
5)Clients and servers exchange messages in a request-response messaging pattern: The client sends a request, and the server returns a response.
