Ars Technica runs a nice overview article “How the Internet works: Submarine fiber, brains in jars, and coaxial cables“. Â It features plenty of cool images, statistics, and details of the Internet wiring from under the sea to the last mile to the last 100 meters. Â It’s mostly focused on UK, but it provides a good understanding of what’s involved in the modern day connectivity.
P.S.: On a less serious note, here’s The IT Crowd take on how the Internet works. Â Thanks to Maxym Balabaev for a reminder.
