Pr Cticas De Redes De Rea Local E Interconexi N De Redes

La obra parte de la necesidad de una combinación equilibrada entre lo teórico y lo práctico. El texto se dividide en dos partes: la inicial dedicada a los referentes a redes de datos, y la segunda dedicada a las redes industriales. Algunas de las prácticas planteadas tienen como propósito que el estudiante evidencie que hay una convergencia e interconectividad entre ambos tipos de redes. Cada una de las prácticas va acompañada de una serie de preguntas, las cuales son una invitación a que el estudiante profundice en los conceptos que, por otra parte, le permitirá efectuar un desarrollo mucho más enriquecedor.

How an electronically connected world will shape cities and urban relationships of the future. The global digital network is not just a delivery system for email, Web pages, and digital television. It is a whole new urban infrastructure—one that will change the forms of our cities as dramatically as railroads, highways, electric power supply, and telephone networks did in the past. In this lucid, invigorating book, William J. Mitchell examines this new infrastructure and its implications for our future daily lives. Picking up where his best-selling City of Bits left off, Mitchell argues that we must extend the definitions of architecture and urban design to encompass virtual places as well as physical ones, and interconnection by means of telecommunication links as well as by pedestrian circulation and mechanized transportation systems. He proposes strategies for the creation of cities that not only will be sustainable but will make economic, social, and cultural sense in an electronically interconnected and global world. The new settlement patterns of the twenty-first century will be characterized by live/work dwellings, 24-hour pedestrian-scale neighborhoods rich in social relationships, and vigorous local community life, complemented by far-flung configurations of electronic meeting places and decentralized production, marketing, and distribution systems. Neither digiphile nor digiphobe, Mitchell advocates the creation of e-topias—cities that work smarter, not harder.

This is the first in-depth guide to global community psychology research and practice, history and development, theories and innovations, presented in one field-defining volume. This book will serve to promote international collaboration, enhance theory utilization and development, identify biases and barriers in the field, accrue critical mass for a discipline that is often marginalized, and to minimize the pervasive US-centric view of the field.

This work opens with an accessible introduction to computer networks, providing general definitions of commonly used terms in networking. This is followed by a detailed description of the OSI model, including the concepts of connection-oriented and connectionless communications. The text carefully elaborates the specific functions of each layer, along with what is expected of protocols operating at each layer. Next, the journey of a single packet, from source to destination, is described in detail. The final chapter is devoted to the TCP/IP model, beginning with a discussion of IP protocols and the supporting ARP, RARP and In ARP protocols. The work also discusses the TCP and UDP protocols operating at the transport layer and the application layer protocols HTTP, DNS, FTP, TFTP, SMTP, POP3 and Telnet. Important facts and definitions are highlighted in gray boxes found throughout the text.

Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.
