Let’s be real—the internet is something most of us use every single day without thinking twice. We use it to scroll social media, check email, watch Netflix, join Zoom calls, or ask Google random questions. But… What is the internet? And how does it actually work?
If you’ve ever wondered what happens when you type a website into your browser, you’re in the right place. Let’s break it down—no tech jargon required (unless you want it).
The internet is basically a massive network of connected computers all over the world. Imagine a giant spider web, where each thread connects one device to another. Those devices could be phones, laptops, servers (which store websites and apps), or even smart fridges.
When you use the internet, your device becomes a part of that web. It can send and receive data—like loading a webpage, streaming a video, or sending a message.
Pretty cool, right?
(Here’s the fun part, but still beginner-friendly!)
Let’s walk through what happens behind the scenes when you click a link or enter a web address.
Say you type www.google.com into your browser and hit enter. Your device is sending a request to a special kind of computer called a server, which is basically where the website lives.
Your request travels across a digital highway made up of devices called routers and switches. Routers decide which path your data should take, and switches help direct that data through networks quickly and efficiently.
Every website lives at a specific IP address (kind of like a digital phone number). But you don’t want to memorize something like 142.250.190.78 every time you visit Google. That’s where DNS (Domain Name System) steps in. It translates easy-to-remember names (like google.com) into those numerical addresses your device needs.
When a website sends data back to you, it doesn’t arrive all at once. It’s split into smaller chunks called packets. Think of them like puzzle pieces—your browser puts them back together to show you the full page.
Simple Breakdown
Here’s a real-world-style step-by-step of how it all goes down:
1. You type a web address (like www.example.com) into your browser.
2. Your device asks DNS to find the matching IP address.
3. The request zips through various routers and switches across the internet.
4. The server for that website gets your request, then sends back the content in packets.
5. Your browser reassembles everything and displays the full website.
All of this usually happens in just a second or two. Wild, right?
