In client server model we have one or multiple clients that request for the service.

And the server is used to provide the response for the clients.

Client server model is like a request response relationship between the client and the server that is used to get data from the server.

Two remote application processes can communicate mainly in two different fashions:

• Peer-to-peer:  For this kind of communication we need same type of configuration on both the side.

• Client-Server: One remote process acts as a Client and requests some resource from another application process acting as Server.

In client-server model, any process can act as Server or Client. It is not the type of machine, size of the machine, or its computing power which makes it server; it is the ability of serving request that makes a machine a server.
