An accessible, comic book-like, illustrated introduction to how the internet works under the hood, designed to give people a basic understanding of the technical aspects of the Internet that they need in order to advocate for digital rights. The internet has profoundly changed interpersonal communication, but most of us don't really understand how it works. What enables information to travel across the internet? Can we really be anonymous and private online? Who controls the internet, and why is that important? And... what's with all the cats? How the Internet Really Works answers these questions and more. Using clear language and whimsical illustrations, the authors translate highly technical topics into accessible, engaging prose that demystifies the world's most intricately linked computer network. Alongside a feline guide named Catnip, you'll learn about: • The "How-What-Why" of nodes, packets, and internet protocols • Cryptographic techniques to ensure the secrecy and integrity of your data • Censorship, ways to monitor it, and means for circumventing it • Cybernetics, algorithms, and how computers make decisions • Centralization of internet power, its impact on democracy, and how it hurts human rights • Internet governance, and ways to get involved This book is also a call to action, laying out a roadmap for using your newfound knowledge to influence the evolution of digitally inclusive, rights-respecting internet laws and policies. Whether you're a citizen concerned about staying safe online, a civil servant seeking to address censorship, an advocate addressing worldwide freedom of expression issues, or simply someone with a cat-like curiosity about network infrastructure, you will be delighted -- and enlightened -- by Catnip's felicitously fun guide to understanding how the internet really works!

Whether we realize it or not, we think of our brains as computers. In neuroscience, the metaphor of the brain as a computer has defined the field for much of the modern era. But as neuroscientists increasingly reevaluate their assumptions about how brains work, we need a new metaphor to help us ask better questions. The computational neuroscientist Daniel Graham offers an innovative paradigm for understanding the brain. He argues that the brain is not like a single computer—it is a communication system, like the internet. Both are networks whose power comes from their flexibility and reliability. The brain and the internet both must route signals throughout their systems, requiring protocols to direct messages from just about any point to any other. But we do not yet understand how the brain manages the dynamic flow of information across its entire network. The internet metaphor can help neuroscience unravel the brain’s routing mechanisms by focusing attention on shared design principles and communication strategies that emerge from parallel challenges. Highlighting similarities between brain connectivity and the architecture of the internet can open new avenues of research and help unlock the brain’s deepest secrets. An Internet in Your Head presents a clear-eyed and engaging tour of brain science as it stands today and where the new paradigm might take it next. It offers anyone with an interest in brains a transformative new way to conceptualize what goes on inside our heads.

Is the Internet erasing national borders? Will the future of the Net be set by Internet engineers, rogue programmers, the United Nations, or powerful countries? Who's really in control of what's happening on the Net? In this provocative new book, Jack Goldsmith and Tim Wu tell the fascinating story of the Internet's challenge to governmental rule in the 1990s, and the ensuing battles with governments around the world. It's a book about the fate of one idea--that the Internet might liberate us forever from government, borders, and even our physical selves. We learn of Google's struggles with the French government and Yahoo's capitulation to the Chinese regime; of how the European Union sets privacy standards on the Net for the entire world; and of eBay's struggles with fraud and how it slowly learned to trust the FBI. In a decade of events the original vision is uprooted, as governments time and time again assert their power to direct the future of the Internet. The destiny of the Internet over the next decades, argue Goldsmith and Wu, will reflect the interests of powerful nations and the conflicts within and between them. While acknowledging the many attractions of the earliest visions of the Internet, the authors describe the new order, and speaking to both its surprising virtues and unavoidable vices. Far from destroying the Internet, the experience of the last decade has lead to a quiet rediscovery of some of the oldest functions and justifications for territorial government. While territorial governments have unavoidable problems, it has proven hard to replace what legitimacy governments have, and harder yet to replace the system of rule of law that controls the unchecked evils of anarchy. While the Net will change some of the ways that territorial states govern, it will not diminish the oldest and most fundamental roles of government and challenges of governance. Well written and filled with fascinating examples, including colorful portraits of many key players in Internet history, this is a work that is bound to stir heated debate in the cyberspace community.
