ISBN: 9798188691066 - how the internet reaches your screen: the hidden journey of every click, from packet to pixels (1 Ergebnisse)

Taschenbuch. Zustand: Neu. Neuware - You click a link, and in the blink of an eye a page from the other side of the planet appears on your screen. It feels like magic, but it is not. It is one of the most astonishing feats of engineering humanity has ever built-a hidden system of packets, routers, cables, and clever agreements that quietly moves your data across the world and back in a fraction of a second.In this vivid, accessible book, Edward Callenford follows a single click on its journey. You will see how a message is broken into tiny packets, how routers and the internet backbone pass those packets from hand to hand, how fiber-optic cables on the ocean floor link the continents, how DNS turns a human-friendly name into a machine address, and how the last mile finally carries the data into your home and onto your display. Along the way, from Paul Baran's Cold War vision of a network that could survive a nuclear strike to the modern undersea cables that carry almost all intercontinental traffic, every idea is grounded in real history and real infrastructure.Featuring twenty-four original diagrams that make the invisible flow of data easy to grasp, this is a book for the curious-students, travelers, and anyone who has ever wondered what really happens between the click and the page.
