Book Description
Este libro sobre redes se dirige tanto a principiantes que quieran conocer las redes informáticas, como a informáticos más experimentados que deseen reforzar y actualizar sus conocimientos. Se presentan los principios básicos (normas, arquitecturas comunes, cableado, cifrado de datos, topología, redes inalámbricas, interconexión de redes...) y los diferentes protocolos existentes en las redes informáticas (Ethernet, Wi-Fi, Bluetooth, ADSL, WiMax...) desde un punto de vista operativo, sin confundir al lector en un discurso demasiado teórico. Se examina la configuración de red para Windows, Linux, Mac OSX y Android. La parte dedicada al almacenamiento se presenta de manera detallada explicando claramente los términos NAS, SAN, zoning, Fiber Channel, FCoE e iSCSI; igualmente se describen los protocolos de replicaciones entre bahías. Se explica en detalle el funcionamiento de ladeduplicación para las copias de seguridad así como los WAAS. Así mismo, se muestra un resumen sobre la virtualización que permite al lector comprender los problemas, ventajas e inconvenientes aportados por las diferentes soluciones del mercado.También se abordan las tecnologías ATM y otras conexiones de tramas. Desde un punto de vista del hardware de red, se explica el algoritmo de Spanning tree, así como el funcionamiento de VSS. Respecto al enrutamiento, se revisan los protocolos RIP, OSPF y BGP, así como HSRP. Se presentan en detalle los protocolos TCP/IP: en particular la descomposición en sub-redes en IPv4, así como un nuevo enfoque completo del direccionamiento IP v6 (incluyendo VoIP). Se examinan igualmente los servicios de red como DHCP, DNS, NTP o SNMP. Un capítulo trata de los principios básicos deseguridad frente a las amenazas que pueden afectar a una red. El anexo proporciona una lista de los acrónimos más significativos en el mundo de las redes informáticas. Los capítulos del libro: Prólogo – Presentación de los conceptos de red – Estandarización de protocolos – Transmisión de datos en la capa física – Software de comunicación – Arquitectura de red e interconexión – Capas bajas de las redes personales y locales – Protocolos de redes MAN y WAN – Protocolos de capas medias y altas – Principios de protección de una red – Reparación de una red – Anexos

Book Description
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.
