Client-Server Architecture

The client-server architecture is a fundamental model in networking, where multiple clients (users or devices) request and receive services from a centralized server.

This model underpins many of our everyday online interactions, from browsing the web to accessing email.

Below is an explanation.

1. Client:

   • The client is any device or application that makes requests to a server for resources or services. Examples include web browsers, email clients, and mobile apps.

2. Server:

   • The server is a computer or program that provides resources or services to multiple clients. Examples include web servers, database servers, and file servers.

3. Communication:

   • Clients and servers communicate over a network using specific protocols (e.g., HTTP for web traffic). The client sends a request to the server, which processes the request and sends back the appropriate response.

4. Examples:

   • Web browsing: Your web browser (client) requests web pages from a web server.
   • Email: Your email client (client) retrieves emails from an email server.

Understanding the client-server architecture helps in grasping how data and services are accessed over the internet. This model is scalable, efficient, and forms the backbone of modern networking.
