An accessible illustrated introducton to the networks we use every day, from Facebook and Google to WiFi and the Internet What makes WiFi faster at home than at a coffee shop? How does Google order search results? Is it really true that everyone on Facebook is connected by six steps or less? The Power of Networks answers questions like these for the first time in a way that all of us can understand. Using simple language, analogies, stories, hundreds of illustrations, and no more math than simple addition and multiplication, Christopher Brinton and Mung Chiang provide a smart and accessible introduction to the handful of big ideas that drive the computer networks we use every day. The Power of Networks unifies these ideas through six fundamental principles of networking. These principles explain the difficulties in sharing network resources efficiently, how crowds can be wise or not so wise depending on the nature of their connections, why there are many layers in a network, and more. Along the way, the authors also talk with and share the special insights of renowned experts such as Google’s Eric Schmidt, former Verizon Wireless CEO Dennis Strigl, and “fathers of the Internet” Vint Cerf and Bob Kahn.
Social Networks at Work provides the latest thinking, from top-notch experts, on social networks as they apply to industrial and organizational (I/O) psychology. Each chapter provides an in-depth review along with discussions of future research and managerial implications of the social network perspective. Altogether, the volume illustrates the importance of adding a social capital perspective to the traditional human capital focus of I/O psychology. The volume is organized into two groups of chapters: the first seven chapters focus on specific network concepts (such as centrality, affect, negative ties, multiplexity, cognition, and structural holes) applied across a variety of topics. The remaining eight chapters focus on common I/O topics (such as personality, creativity, turnover, careers, person–environment fit, employment, teams, and leadership) and examine each from a network perspective, applying a variety of network concepts to the topic. This volume is suited for students and academics interested in applying a social network perspective to their work, as well as for practicing managers. Each topic area provides a useful review and guide for future research, as well as implications for managerial action.
The goal of this textbook is to provide enough background into the inner workings of the Internet to allow a novice to understand how the various protocols on the Internet work together to accomplish simple tasks, such as a search. By building an Internet with all the various services a person uses every day, one will gain an appreciation not only of the work that goes on unseen, but also of the choices made by designers to make life easier for the user. Each chapter consists of background information on a specific topic or Internet service, and where appropriate a final section on how to configure a Raspberry Pi to provide that service. While mainly meant as an undergraduate textbook for a course on networking or Internet protocols and services, it can also be used by anyone interested in the Internet as a step–by–step guide to building one's own Intranet, or as a reference guide as to how things work on the global Internet
Hands-on networking experience, without the lab! The best way to learn about network protocols is to see them in action. But that doesn't mean that you need a lab full of networking equipment. This revolutionary text and its accompanying CD give readers realistic hands-on experience working with network protocols, without requiring all the routers, switches, hubs, and PCs of an actual network. Computer Networking: Internet Protocols in Action provides packet traces of real network activity on CD. Readers open the trace files using Ethereal, an open source network protocol analyzer, and follow the text to perform the exercises, gaining a thorough understanding of the material by seeing it in action. Features * Practicality: Readers are able to learn by doing, without having to use actual networks. Instructors can add an active learning component to their course without the overhead of collecting the materials. * Flexibility: This approach has been used successfully with students at the graduate and undergraduate levels. Appropriate for courses regardless of whether the instructor uses a bottom-up or a top-down approach. * Completeness: The exercises take the reader from the basics of examining quiet and busy networks through application, transport, network, and link layers to the crucial issues of network security.

This practical guide shows how to facilitate collaboration among diverse individuals and organizations to navigate complexity and create change in our interconnected world. The social and environmental challenges we face today are not only complex, they are also systemic and structural and have no obvious solutions. They require diverse combinations of people, organizations, and sectors to coordinate actions and work together even when the way forward is unclear. Even so, collaborative efforts often fail because they attempt to navigate complexity with traditional strategic plans, created by hierarchies that ignore the way people naturally connect. By embracing a living-systems approach to organizing, impact networks bring people together to build relationships across boundaries; leverage the existing work, skills, and motivations of the group; and make progress amid unpredictable and ever-changing conditions. As a powerful and flexible organizing system that can span regions, organizations, and silos of all kinds, impact networks underlie some of the most impressive and large-scale efforts to create change across the globe. David Ehrlichman draws on his experience as a network builder; interviews with dozens of network leaders; and insights from the fields of network science, community building, and systems thinking to provide a clear process for creating and developing impact networks. Given the increasing complexity of our society and the issues we face, our ability to form, grow, and work through networks has never been more essential.
