At a high level, routers are the traffic directors of the digital world. They are networking devices that connect computer networks, forwarding data packets between them. This seemingly simple function is what makes the internet, and indeed most modern communication, possible. Whether you're sending an email, streaming a video, or browsing a website, a router is working behind the scenes to ensure your data reaches its intended destination and that data from elsewhere can find its way to you. Understanding routers is fundamental to understanding how information flows across the globe.
