Client Server Model

Before stepping ahead, we should know about the Node, Client and Server.


Node is a component or terminal connected to a network. The components like laptops, PDAs, Internet enabled mobiles etc., can be considered as node in a computer network.


It is a node computer that establishes connection with the server, collects data from the user, sends it to the server, receives information from the server and presents it to the user.


In the context of client-server model, server is the counter part of client. It is a computer that serves queries from the client. The programs which respond to the request of clients are known as server applications. The computer designed to run server application is known as server machine. Web server, database server and mail server are some examples of servers.

The Client Server Model is an architecture of computer network where client and server interact by means of a network. Client gathers data from the user as input and sends request to the server. Server processes the request and sends the requested information to the client. Railway reservation system, online banking and online gaming are examples of client-server model.
