How Information Travels Across the Internet
Now that we have some idea on How the Internet Works, let's take a look on how information travels across the internet.
In order to access a web page, you have to connect to the web server containing the information that you are looking for. When you open your web browser and connect to a site, your computer sends an electronic request over your internet connection to your Internet Service provider (ISP). The ISP routes the request to a server further up the line in the internet, and will eventually get to the Domain Name Server (DNS). The DNS will look for the domain name you’ve searched for (like www.google.com). If it finds the domain, it will send the request to the correct servers IP address. If it fails to find a match, it will send the request up the line to a server that has more information.
The request will eventually wind up at its intended target server. That server will then respond by sending the requested file in a series of Packets. Packets are parts of a file that range between 1,000-1,500 bytes (unit of digital information that is eight binary digits long). These packets have headers and footers that tell the computers what’s in the packet and how the information fits with other packets to create an entire file. Each packet travels back up the network and back down to your computer, generally traveling the path of least resistance. This is important because packets can take multiple paths to get to their destination and is possible for the information route around congested or heavily traffic areas on the Internet. When the packets get to you, your device arranges them in compliance with the rule. of the protocol. The finished product is the page you were searching for. This applies to other types of files also like when sending an email. It gets broken down into different packets before flying through the internet. VoIP, or Voice Over Internet Protocol, is making phone calls over internet.
Fun Fact: If some of the connections remained, entire sections of the internet could go down and information could still travel from one place to another. It would just take longer to get there.
We hope this has been useful information for you!
