The web is not just a collection of pages; it’s a complex system that connects people and information globally. Let’s explore the intricacies of the web in a structured manner.
1. What is the Web?
The web, short for the World Wide Web, is a system of interlinked hypertext documents accessed via the Internet. It allows users to view and interact with a variety of content, including text, images, videos, and more. Here’s a simple breakdown:
- Internet vs. Web: The Internet is the infrastructure (servers, routers, cables), while the web is the content that travels over this infrastructure.
- Web Browsers: Tools like Chrome, Firefox, and Safari that allow users to access web pages.
- Web Pages: Documents displayed in a browser, written in HTML (HyperText Markup Language).
2. How Does the Web Function?
The functioning of the web can be broken down into several key components:
2.1. Domain Names and URLs
- Domain Names: A readable address (like www.example.com) that points to an IP address.
- URLs (Uniform Resource Locators): The complete address used to access a specific resource on the web.
2.2. Web Servers and Hosting
