Computer Networks: A Systems Approach, Fifth Edition, explores the key principles of computer networking, with examples drawn from the real world of network and protocol design. Using the Internet as the primary example, this best-selling and classic textbook explains various protocols and networking technologies. The systems-oriented approach encourages students to think about how individual network components fit into a larger, complex system of interactions. This book has a completely updated content with expanded coverage of the topics of utmost importance to networking professionals and students, including P2P, wireless, network security, and network applications such as e-mail and the Web, IP telephony and video streaming, and peer-to-peer file sharing. There is now increased focus on application layer issues where innovative and exciting research and design is currently the center of attention. Other topics include network design and architecture; the ways users can connect to a network; the concepts of switching, routing, and internetworking; end-to-end protocols; congestion control and resource allocation; and end-to-end data. Each chapter includes a problem statement, which introduces issues to be examined; shaded sidebars that elaborate on a topic or introduce a related advanced topic; What's Next? discussions that deal with emerging issues in research, the commercial world, or society; and exercises. This book is written for graduate or upper-division undergraduate classes in computer networking. It will also be useful for industry professionals retraining for network-related assignments, as well as for network practitioners seeking to understand the workings of network protocols and the big picture of networking. - Completely updated content with expanded coverage of the topics of utmost importance to networking professionals and students, including P2P, wireless, security, and applications - Increased focus on application layer issues where innovative and exciting research and design is currently the center of attention - Free downloadable network simulation software and lab experiments manual available

The turbulence of the current times has dramatically transformed the world’s economic geographies. The scale and scope of such changes require urgent attention. With intellectual roots dating to the nineteenth century, economic geography has traditionally sought to examine the spatial distributions of economic activity and the principles that account for them. More recently, the field has turned its attention to a range of questions relating to: globalization and its impact on different peoples and places; economic inequalities at different geographic scales; the development of the knowledge-based economy; and the relationship between economy and environment. Now, more than ever, the changing fortunes of peoples and places demands our attention. Economic Geography provides a stimulating and innovative introduction to economic geography by establishing the substantive concerns of economic geographers, the methods deployed to study them, the key concepts and theories that animate the field, and the major issues generating debate. This book is the first to address the diverse approaches to economic geography as well as the constantly shifting economic geographies on the ground. It encompasses traditional approaches, albeit from a critical perspective, while providing a thorough, accessible and engaging examination of the concerns, methods and approaches of the ‘new economic geography’. This unique introductory text covers the breadth of economic geography while engaging with a range of contemporary debates at the cutting-edge of the field. Written in an accessible and lucid style, this book offers a thorough and systematic introductory survey. It is enhanced by pedagogical features throughout including case studies dealing with topics ranging from the head office locations of the Fortune 500, Mexico’s maquiladoras to China’s investments in Southern Africa. This book also contains exercises based on the key concepts and annotated further reading and websites.

This book focuses on neighborhoods and the people living in them. It describes differences among neighborhoods in terms of their social and institutional structure, attitudes of the residents, quality of life, and the characteristics of the residents. The book is based on the results of a survey of almost 6,000 residents living throughout the city of Pittsburgh. As such it provides the basis for examining groups of people as well as whole neighborhoods. The communal aspects of urban living are discussed in Chapters 1 and 2; attachment toward the neighborhood in Chapter 3; importance of reli gion, life cycle, and race in Chapter 4; various aspects of individual social support systems and neighborhood social fabric in Chapters 5, 6, and 7; the contextual aspects of the neighborhood environment in Chapters 8 and 9; and the implications for urban policy in Chapter 10. The results of the analysis described in the book pro vide a detailed understanding of differences in the struc ture and composition of urban neighborhoods, and they show why some groups of people are drawn into their neighborhoods whereas others rely more upon the wider community to meet a variety of needs. The analysis pro vides the framework in which to address the implications for urban policy, particularly with respect to mental health prevention and neighborhood and community renewal.

An analysis of the influence of urban life on society compares and contrasts personal relationships in large cities with those in small towns.

The Connected City explores how thinking about networks helps make sense of modern cities: what they are, how they work, and where they are headed. Cities and urban life can be examined as networks, and these urban networks can be examined at many different levels. The book focuses on three levels of urban networks: micro, meso, and macro. These levels build upon one another, and require distinctive analytical approaches that make it possible to consider different types of questions. At one extreme, micro-urban networks focus on the networks that exist within cities, like the social relationships among neighbors that generate a sense of community and belonging. At the opposite extreme, macro-urban networks focus on networks between cities, like the web of nonstop airline flights that make face-to-face business meetings possible. This book contains three major sections organized by the level of analysis and scale of network. Throughout these sections, when a new methodological concept is introduced, a separate ‘method note’ provides a brief and accessible introduction to the practical issues of using networks in research. What makes this book unique is that it synthesizes the insights and tools of the multiple scales of urban networks, and integrates the theory and method of network analysis.

Shows how digital media connects people to their lived environments Every day, millions of people turn to small handheld screens to search for their destinations and to seek recommendations for places to visit. They may share texts or images of themselves and these places en route or after their journey is complete. We don’t consciously reflect on these activities and probably don’t associate these practices with constructing a sense of place. Critics have argued that digital media alienates users from space and place, but this book argues that the exact opposite is true: that we habitually use digital technologies to re-embed ourselves within urban environments. The Digital City advocates for the need to rethink our everyday interactions with digital infrastructures, navigation technologies, and social media as we move through the world. Drawing on five case studies from global and mid-sized cities to illustrate the concept of “re-placeing,” Germaine R. Halegoua shows how different populations employ urban broadband networks, social and locative media platforms, digital navigation, smart cities, and creative placemaking initiatives to turn urban spaces into places with deep meanings and emotional attachments. Through timely narratives of everyday urban life, Halegoua argues that people use digital media to create a unique sense of place within rapidly changing urban environments and that a sense of place is integral to understanding contemporary relationships with digital media.
