What is the World Wide Web (WWW)?

The World Wide Web (WWW) is a distributed information system based on hypertext. It is a collection of interconnected web pages accessible via the Internet using a browser.

Key components:

• URL (Uniform Resource Locator): Address of each web page.
• HTTP (Hypertext Transfer Protocol): Protocol for data transfer between browser and web server.
• HTML (Hypertext Markup Language): Markup language for creating web pages.
• Browser: Client application for viewing web pages.
• Web server: Software that stores and provides access to web pages.

WWW operates on a client-server model:

1. User enters URL in browser (client).
2. Browser sends an HTTP request to the web server.
3. Web server processes the request and sends back HTML code via HTTP.
4. Browser interprets HTML and displays the web page.

WWW is part of the Internet, providing a convenient way to navigate and access information through hyperlinks.
