World Wide Web (WWW)

I. Introduction to the World Wide Web (WWW)

The World Wide Web (WWW), commonly known as the Web, is a vast information space on the Internet that allows users to access and share multimedia content over a network of interconnected computers. Developed by Tim Berners-Lee in the late 20th century, the Web has transformed the way we access and interact with information. It's important to note that the Internet and the World Wide Web are not the same; rather, the Web is a subset of the broader Internet.

II. Key Components of the World Wide Web

Web Browsers:

Web browsers are software applications that allow users to access and view websites.

Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.

Web Servers:

Web servers are computers that store and deliver web content to users.

They respond to user requests by providing web pages, images, videos, and other resources.

Uniform Resource Locator (URL):

A URL is a web address used to locate resources on the Web.

It consists of a protocol (e.g., http, https), domain name, and path.

Hyperlinks:

Hyperlinks, or simply links, are clickable elements that connect different web pages.

They enable users to navigate between related web pages and resources.

Web Pages:

Web pages are documents created using HTML (Hypertext Markup Language) to display content.

They may contain text, images, videos, forms, and other multimedia elements.

HTML (Hypertext Markup Language):

HTML is the standard markup language used to create and structure web content.

It uses tags to define elements and their formatting.

III. How the World Wide Web Works

Client-Server Architecture:

The WWW operates on a client-server architecture.

Clients (browsers) request resources, and servers provide those resources in response.

Request-Response Cycle:

When a user enters a URL in a browser, the browser sends a request to the appropriate web server.

The server processes the request and sends back the requested content, forming a request-response cycle.

IV. Diagram: Components and Working of the World Wide Web

The diagram illustrates the components of the World Wide Web and their interactions.

It shows a user using a web browser to send a request (GET request) to a web server using a URL.

The web server receives the request, processes it, and sends a response containing the requested web page.

The web page is displayed in the user's browser, and it may contain hyperlinks to other resources hosted on different servers.]

V. Conclusion

The World Wide Web has revolutionized how we access, share, and interact with information. Understanding its key components and functioning is crucial for anyone navigating the digital landscape. As we continue to evolve in the digital age, the Web remains a cornerstone of our online experiences.
