Client-Server Model

The client-server architecture is a common design pattern used in computer networking, including the internet. In this architecture, there are two types of software components: clients and servers. A server is a computer program or device that provides a service to one or more client programs. A client is a computer program or device that requests services or resources from a server. In the context of the internet, a client is typically a web browser or a mobile app, while a server is a web server or an application server.


When a client wants to access a resource or service on the internet, it sends a request to the server. The server processes the request and sends back a response to the client, typically in the form of HTML, JSON, or some other format that the client can understand. This client-server model is what enables the internet to function as a distributed system. By breaking up tasks into smaller components and having specialized servers handle each component, the internet can provide a wide range of services and resources to millions of users around the world. Overall, the client-server architecture is an essential part of how the internet works and is what enables users to access and interact with the vast array of resources available on the web.
