HOW EXACTLY DOES INTERNET ACTUALLY WORKS? (part 2)
continued......
Now the message that you're sending the ISP is, I want to see Google.com and the ISP will then relay that message to something called a DNS server a domain name system server and a DNS server is essentially just a souped up phone📞📕 book. And what happens when you make that request through your browser is the DNS server will look up in its database as to what is the exact IP address of that web site that you're trying to access and every single computer💻 that's connected to the internet has an IP address. This is like a postal address for your computer so that when people need to send and receive files on the Internet each computer can be located by a unique IP address. And once that DNS server finds the IP address it sends that back to your browser. So now you know the exact address where you can find the Google home page. So the next thing that happens is you will send a direct request to that address through your Internet service provider. And this message will be delivered via what's called the Internet backbone. Now the Internet backbone isn't some sort of analogy for some clever programming. It's literally the backbone of the Internet. And if you had a submarinecablemap.com you can view👀 all of the underwater cables that power the Internet and the Internet is made up of these huge sprawling masses of wires 〰connecting all of the world's Internet users as you can imagine. It's a pretty complex world out there. Now if I'm sitting in London and I want to see a web site that's hosted in the United States then my browser would have to make a request that goes through one of these cables under the Atlantic Ocean🌊 in order to reach the United States. And once that computers receive my request they'll send back all of the relevant data📁 again through these giant cables and to navigate all of this crazy underwater and above water wires. All I have is an IP address. It's like as if I'm sending a letter✉ halfway across the world🌐 and my only hope for my letter to reach my friend is that postal address on the front of the envelope. So once I've gotten the IP address of the website that I want to access then my browser sends another message through the Internet service provider via the Internet backbone to the server that is located at that address 216.58.210.46 and the computer that's located at that address is of course the Google server and on the server there's all of the files I would need in order to be able to view the Google home page. So the server then sends all of those files back to me through the Internet backbone and I get to see the Google home page in my browser and all of that happens in a matter of milliseconds and just to imagine the journey that my data 📁has gone on traveling through the world🌐 thousands of times ⌛per day. So why don't you give it a go.👉 Open up your browser and type in 216.58.210.46 and hit enter👇 to see the Google home page being served up to you being served up to you through the Internet.
