Key Components of the World Wide Web

• Hypertext: A system of linked documents, allowing users to navigate between them by clicking on links.
• Hyperlinks: Links that connect different web pages, enabling users to jump between them.
• Web Servers: Computers that store web pages and other files and make them available to users.
• Web Browsers: Software applications that allow users to access and view web pages.
• Uniform Resource Locator (URL): A unique address that identifies a specific resource on the web.
• Domain Name System (DNS): A hierarchical system that translates domain names into IP addresses.
• Internet Protocol (IP): A set of rules that govern how data is transmitted over the internet.

How the World Wide Web Works

1. Request: When a user enters a URL in their web browser, the browser sends a request to the web server hosting the website.
2. DNS Lookup: The browser uses the DNS to translate the domain name into an IP address.
3. Connection: The browser establishes a connection with the web server using the IP address.
4. Response: The web server sends the requested web page to the browser.
5. Display: The browser interprets the HTML code of the web page and displays it on the user’s screen.

Types of Web Pages

• Static Web Pages: Pages that are stored as fixed files on a web server and do not change dynamically.
• Dynamic Web Pages: Pages that are generated on the fly by a web server based on user input or other factors.
• Interactive Web Pages: Pages that allow users to interact with the content, such as filling out forms or playing games.

Web Technologies

• HTML (HyperText Markup Language): The language used to create the structure and content of web pages.
• CSS (Cascading Style Sheets): A language used to style the appearance of web pages, including fonts, colors, and layout.
• JavaScript: A scripting language used to add interactivity and dynamic behavior to web pages.
• PHP (Hypertext Preprocessor): A server-side scripting language used to create dynamic web pages.
• Python: A general-purpose programming language often used for web development.

Impact of the World Wide Web

• Information Access: The web has made information readily available to anyone with an internet connection.
