Client-Server Architecture:-
The term 'Client-Server' Architecture is a client requesting a server for service by sending request. The Server will process the result for that request then it will send back the response to that client.So there is two way appoach between client and server is called Requesting and Responding.This type of relationship is called as client/server architecture.
In a single computer can multiple servers such as web servers,file server,DHCP,DNS...etc Whether a computer is a client, a server, or both is determined by the nature of the application that requires the service functions. Client software can also communicate with server software within the same computer.Single server can support numerous client simultaneously.Number of servers can be interconnected together in a pool to increase the performance,load balance and increase number of clients. Communication between servers is called as server to server communications or inter-server communication.
In a school a class room is the best example for this network model. just assume a class room.in that class room students are gathering information from teachers,so clients means students, server means teachers,i hope it is funny example.
Internet is the best example for client-server architecture network.for example if want to open a Google.com in your computer or mobile or tablet what ever it is,what you will do? you will open web browser and then you will type Google.com in your web browser address bar.after that do you know what will your computer,mobile will do?
Your computer browsers is a client program it will send the query for Google webpage to Google server.Then Google server will respond and send back Google webpage to that client.
