The Architecture of WWW
The architecture of the World Wide Web is a complex system that enables the seamless exchange of information across the internet. At its core, the web is based on a client-server model, where clients (web browsers) request resources from servers (web hosts) using the Hypertext Transfer Protocol (HTTP). This architecture allows users to access web pages, multimedia content, and web applications from anywhere in the world.
The fundamental building blocks of the web include Uniform Resource Locators (URLs), Hypertext Markup Language (HTML), and Cascading Style Sheets (CSS). URLs serve as unique identifiers for web resources, while HTML provides the structure and content of web pages. CSS is used to define the visual presentation of web pages, allowing designers to create visually appealing and responsive layouts.
Client-Server Model
The client-server model is the backbone of the World Wide Web, facilitating communication between clients and servers. When a user enters a URL into a web browser, the browser sends an HTTP request to the server hosting the requested resource. The server then processes the request and sends an HTTP response containing the requested content back to the browser.
This interaction is made possible by protocols such as HTTP and HTTPS (Hypertext Transfer Protocol Secure), which ensure secure and reliable data transmission between clients and servers. HTTPS, in particular, uses encryption to protect sensitive information, making it essential for e-commerce and online transactions.
