The second edition of the Handbook of Data Communications and Networks covers many of the key areas in modern communication systems. It is split into several sections, including: Data Communications, Interfaces, Networks, Network Protocols, Networking Elements, Session Protocols, Network Operating Systems.

Computing is an area which continues to grow. This book covers the main areas of computing, including programming, computer hardware, operating systems, the Internet, data communications and networking. It uses practical examples to show basic concepts, is packed full of diagrams showing important principles, and contains multiple choice questions to test knowledge and understanding. The book uses a readable style, and is aimed at students studying for Advanced GNVQ, A level, HND and BSc courses.

The first book ever to give a complete picture of the workings of a PC! A comprehensive guide to the component systems of the PC, this book provides a foundation to the understanding of previous, current and future PC systems, and how the specification of each component of a PC affects the overall system performance. The book outlines each of the main PC processors and contrasts their performance. It also examines each of the main interface devices and shows how they integrate into the main systems. If you are an undergraduate or professional looking for a complete understanding of the internal architecture of the PC, and how it is changing, this book is for you. It explains how systems have evolved from the original PC, keeping its compatibility with previous systems, whilst increasing its power. It also provides an insight into how the PC will evolve in the future. Key chapters: * Motherboards - Analyses typical motherboards and shows how each of the components interfaces together, and how the architecture affects the system performance. * Memory - Shows how chache memory and DRAM memory interface to the system and the processor. * PCI bus - Discusses the fundamentals of the PCI bus and shows its importance in the architecture of modern PCs. * On-line multiple choice tests for students * On-line PowerPoint/HTML slides of all the graphics from the book.

This book provides the student with comprehensive coverage of both networks and system architecture. It aims to introduce the most widely used networking protocols and distributed systems, covering recent developments in distributed processing and the WWW, the use of Internet and Intranets, and the integration of networking into operating systems. The book will be supported by a website offering downloadable Java source code, on-line testing for students, and project-related WWW work.

The use of data communications and computer networks is constantly increasing, bringing benefits to most of the countries and peoples of the world, and serving as the lifeline of industry. Now there is a textbook that discusses data communications and networking in a readable form that can be easily understood by students who will become the IS professionals of the future. Advanced Data Communications and Networks provides a comprehensive and practical treatment of rapidly evolving areas. The text is divided into seven main sections and appendices: "General data compression"Video, images, and sound"Error coding and encryption"TCP/IP and the Internet"Network operating systems"LANs/WANs"Cables and connectors Other topics include error detection/correction, image/video compression, digital video, digital audio, TCP/IP, HTTP, electronic mail, HTML, Windows NT, NetWare, UNIX, Fast Ethernet, ATM, FDDI, and much more. Written by a respected academician who is also an accomplished engineer, this textbook uses the author's wide practical experience in applying techniques and theory toward solving real engineering problems. It also includes an accompanying Web site that contains software, source code, and other supplemental information.

Using good practical examples, this new book introduces the reader to the component parts of a PC, showing how high and low level languages communicate with them, and how computers communicate with peripherals.

The authors have taken the 3D FDTD approach to simulate the propagation of electrical signals within and around printed circuit boards (PCBs). This relates to the work currently being carried out into the propagation of very high speed digital pulses in PCBs for high bandwidth systems. The authors have further demonstrated the use of parallel processing to reduce simulation time. Visualisation of an applied gaussian pulse from multiple sources within and without a PCB are shown and the techniques used to determine the system characteristics are discussed in this paper.

The authors have applied the 3D FDTD technique to simulate the propagation of electrical signals on a microstrip antenna using a four-transputer array connected to a 386-based PC. This relates to work currently being carried out into the propagation of very high speed digital pulse in printed circuit boards in high bandwidth systems. Methods have been devised by the authors which reduce the amount of stored data and improve run-time. These methods include subgridding, shielded volume and concurrent processing of the problem. Results have been obtained and rre presented in this paper to show improved accuracy and decreased run-time. An analysis of run-time to the number of transputers in an array for optimum operation has been presented. A trade-off between intertransputer communication of segment boundary conditions and the size of each segment has also been discussed in the paper.

This paper discusses privacy enhancing technologies in the field of inter-agency data sharing, a key government objective for efficient public service delivery. We analyse the legal and conceptual framework that governs multi-agency cooperation in particular in the field of child protection work, and develop two approaches to represent relevant data protection ideas computationally in the infrastructure that agencies use to exchange sensitive personal data.

The 3D Finite-Difference Time-Domain (FDTD) method simulates structures in the time-domain using a direct form of Maxwell’s curl equations. This method has the advantage over other simulation methods in that it does not use empirical approximations. Unfortunately, it requires large amounts of memory and long simulation times. This thesis applies parallel processing to the method so that simulation times are greatly reduced. Parallel processing, though, has the disadvantage in that simulation programs require to be segmented so that each processor processes a separate part of the simulation. Another disadvantage of parallel processing is that each processor communicates with neighbouring processors to report their conditions. For large processor arrays this can result in a large overhead in simulation time.Two main methods of parallel processing discussed: Transputer arrays and clustered workstations over a local area network (LAN). These have been chosen because of their relatively cheapness to use, and their widespread availability.The results presented apply to the simulation of a microstrip antenna and to propagation of electrical signals in a printed circuit board (PCB). Microstrip antennas are relatively difficult to simulate in the time-domain because they have resonant pulses. Methods that reduce this problem are discussed in the thesis.The thesis contains a novel analysis of the parallel processing showing, using equations, tables and graphs, the optimum array size for a given inter-processor communication speed and for a given iteration time. This can be easily applied to any processing system.Background material on the 3D FDTD method and microstrip antennas is also provided. From the work on the parallel processing of the 3D FDTD a novel technique for the simulation of the Finite-element (FE) method is also discussed.
