Introduction to Internet & Websites

Imagine being able to talk to someone on the other side of the world in seconds, stream a movie instantly, or launch your own online business from your room. That’s the power of the Internet.

✅ What is the Internet?

The Internet is a massive network of networks — it connects computers and devices globally, allowing them to share information, communicate, and access services 24/7.

Think of it like: a huge system of roads connecting cities (computers) across the globe. Your browser is the car, and websites are the destinations.

📡 How Does the Internet Work?

Let’s break it down simply — the Internet is like a well-organized delivery system, getting information from one place to another in milliseconds. Here`s how it works behind the scenes:

1. Servers Store the Content

Think of servers as powerful computers that store websites, videos, images, and files. Every time you access a website, you`re actually reaching out to a server somewhere in the world asking, “Hey, can you show me this page?”

🧠 Fun Fact: Google alone has over 1 million servers globally!

2. Clients Make the Requests

Your phone, laptop, or tablet is a client. When you type in a website address or click a link, your device sends a request over the internet asking for that content.

💡 It’s like ordering food: Your device places the order, and the server prepares and delivers it.

3. IP Addresses Route the Traffic

Every device on the internet has an IP address (like 192.168.1.1) — it works just like your home address. It ensures the data you requested (like a website or video) gets delivered to the right device.

📦 Imagine if your order had no address — it’d never reach you!

4. DNS Translates Domain Names

You type www.google.com, not an IP number — thanks to the Domain Name System (DNS). It acts like a phonebook, converting human-friendly domain names into IP addresses behind the scenes.

🔎 Try This: Go to your browser and type https://216.58.223.142 — it opens Google too!

5. Browsers Display the Content

Web browsers like Chrome, Safari, Firefox, and Edge take all the code (HTML, CSS, JavaScript) received from the server and render it into a beautiful, clickable website that you can scroll, read, or interact with.

🖥️ Without browsers, you`d just see raw code — not the clean design you`re used to.

6. It All Happens in Seconds

From the moment you click a link to when a webpage loads, millions of data packets travel across fiber optic cables, satellites, and wireless towers to bring information to your screen — in the blink of an eye.
