Real life examples of URLs: Where do they take you?

📚 Quick Study Guide

• 🌐 URLs (Uniform Resource Locators) are addresses for resources on the internet.
• 🧩 A URL consists of several parts: protocol (e.g., `https://`), domain name (e.g., `www.example.com`), path (e.g., `/page1.html`), and sometimes query parameters (e.g., `?id=123`).
• 🔒 `https://` indicates a secure connection using SSL/TLS encryption.
• 📄 The domain name is the human-readable version of an IP address.
• 📂 The path specifies the location of a specific resource on the server.
• 🔑 Query parameters are used to pass information to the server, often for filtering or personalization.
• 🔗 Relative URLs are used for linking within the same website; absolute URLs are used for linking to external websites.
