Today, let's start with the first topic in the Web Development Roadmap:

✅ How the Web Works 🌐📥

📌 1. What happens when you type a URL in your browser? 
▶️ Example: You type www.google.com and hit Enter.

Here’s what happens:

1️⃣ Browser Sends a Request 
Your browser sends a request to the server where the website is stored. This is called an HTTP request.

2️⃣ DNS Resolves the Address 
DNS (Domain Name System) turns www.google.com into an IP address like 142.250.64.78, so it knows where to send the request.

3️⃣ Server Receives the Request 
The server is a computer that stores the website’s files. It processes the request and sends back the HTML, CSS, and JS files.

4️⃣ Browser Displays the Page 
Your browser reads those files and renders the website for you to see.

📌 2. Key Concepts You Should Know

🧠 Client 
Your browser (like Chrome) is the client – it requests the website.

🧠 Server 
The machine that holds the website and responds to your request.

🧠 HTTP 
A protocol – like a language – that browsers and servers use to talk. 
➡️ Example:
⦁ GET – asking for a webpage
⦁ POST – sending form data

🧠 HTML, CSS, JavaScript
⦁ HTML: Gives structure (e.g., headings, paragraphs)
⦁ CSS: Adds style (e.g., colors, layout)
⦁ JS: Adds interaction (e.g., clicks, animations)

📌 Example Flow:

You type: www.example.com 
↓ 
DNS converts it to IP: 93.184.216.34 
↓ 
Your browser sends an HTTP GET request 
↓ 
Server responds with HTML, CSS, JS 
↓ 
Browser renders the page for you!

💡 Every time you visit a website or build one, this process is happening behind the scenes. As a web developer, understanding it helps you debug issues and write better code!
