The internet is just a giant network of computers that talk to each other. When you open a website, your computer (the client) asks another computer (the server) for information.

That's it. Everything else is just details on how that request travels.

• 1. You type: www.example.com
• 2. Your computer asks DNS: "What is the address of example.com?"
• 3. DNS replies: "It's at 93.184.216.34" (an IP address)
• 4. Your computer sends a request to that IP address
• 5. The server finds the webpage and sends it back
• 6. Your browser displays the page 🎉

Computers don't understand names like example.com. They understand numbers called IP addresses. DNS (Domain Name System) converts names into numbers.

      │ (Phonebook)     │ ─────────────────────────>
      └─────────────────┘

Think of it like your phone's contact list: you tap Mom instead of dialing her actual phone number.

Every device on the internet has a unique IP address, like a home address for mail delivery.

Your webpage isn't sent all at once — it's broken into small pieces called packets, sent separately, and reassembled at the destination.

 Original Data: "HELLO WORLD"
 
 Broken into packets:

The Internet connects millions of smaller networks around the world, allowing computers, smartphones, and other devices to communicate with each other. Whenever you open a website, send an email, or watch a video online, your device exchanges data with another device over the Internet.

When you type a website address (such as google.com) into your browser and press Enter, your computer sends a request through your local network to your Internet Service Provider (ISP). The ISP then forwards your request through multiple routers and networks until it reaches the server where the website is hosted.

The server receives your request, processes it, and prepares the required data, such as HTML, CSS, JavaScript, images, and videos. It then sends this data back through the Internet to your device.

Finally, your browser receives the data, puts all the pieces together, and displays the webpage on your screen. This entire process usually happens in just a few milliseconds, making websites appear to load almost instantly.

Behind the scenes, technologies such as DNS, TCP/IP, HTTP/HTTPS, routers, and servers work together to ensure that your data reaches the correct destination quickly, reliably, and securely.
