How the Internet Works: A Simple Guide

The internet is often thought of as something wireless or magical, but in reality, over ninety-five percent of internet traffic travels through physical submarine fiber optic cables. These cables are laid on the ocean floor and connect different countries, enabling fast, long-distance data transmission.

Once data travels through these underwater cables, it arrives at massive, secure data centers. These facilities handle routing and storing the information efficiently. From there, the internet is distributed to local internet service providers (ISPs), who bring it to homes and businesses using technologies like fiber, DSL, or wireless.

Several factors affect your internet speed and quality. These include the reliability of the submarine cables, the infrastructure of your ISP, and the condition of your neighborhood’s network. Even if you’re subscribed to a fast plan, network congestion or maintenance issues in data centers can cause slowdowns.

At home, routers also play a critical role. If many devices are connected at once or your router is outdated, your connection may suffer. Understanding how the internet flows—from global infrastructure to your device—can help you make better decisions about your equipment and providers.
