How the Internet Works (Infrastructure) #16

In this episode of Computer Lessons, we destroy the myth of the "Cloud" and reveal the massive physical machine that powers the Internet. We dive deep into the subsea infrastructure, explaining how hair-thin strands of glass transport 99% of global data across the bottom of the ocean. You will learn about the strict hierarchy of the Internet: Tier 1 backbone providers, the massive Internet Exchange Points (IXPs) where networks shake hands, and the fortress-like security of modern Data Centers. We distinguish the "Internet" from the "World Wide Web," explore the physics of signal repeaters on the ocean floor, and follow the journey of a single click from your home router to a server on the other side of the planet. We also cover the "Last Mile" problem and why your connection speed depends heavily on physical distance.
