Computer Network Hardware

Cluster computers provide a low-cost alternative to multiprocessor systems for many applications. Building a cluster computer is within the reach of any computer user with solid C programming skills and a knowledge of operating systems, hardware, and networking. This book leads you through the design and assembly of such a system, and shows you how to mearsure and tune its overall performance. A cluster computer is a multicomputer, a network of node computers running distributed software that makes them work together as a team. Distributed software turns a collection of networked computers into a distributed system. It presents the user with a single-system image and gives the system its personality. Software can turn a network of computers into a transaction processor, a supercomputer, or even a novel design of your own. Some of the techniques used in this book's distributed algorithms might be new to many readers, so several of the chapters are dedicated to such topics. You will learn about the hardware needed to network several PCs, the operating system files that need to be changed to support that network, and the multitasking and the interprocess communications skills needed to put the network to good use. Finally, there is a simple distributed transaction processing application in the book. Readers can experiment with it, customize it, or use it as a basis for something completely different.

A comprehensive introduction to reliability and availability modeling, analysis, and design at the system, hardware, and software levels Reliability of Computer Systems and Networks presents the fundamentals of reliability and availability analysis for various computer hardware, software, and networked systems. Reliability and availability as major objectives in system design are the focus. Various redundancy and fault-tolerant techniques, as well as error-correcting coding techniques are treated. The author proposes a high-level design approach based on apportioning the reliability and availability goals to subsystems and provides various techniques for achieving these subsystem goals. The next step is an efficient, exact optimization approach based on upper and lower bounds to minimize the number of feasible candidates. The most readily applied methods for analysis are utilized and design techniques are derived from basic principles. Analytical simplifications and approximations are developed to validate the results of computer models used for large-scale complex problems. Coverage includes: Coding and decoding schemes for error detection and correction including chip reliabilityComparison of the reliability and availability of parallel, standby, and majority voting architecturesFormulation, solution, and interpretation of Markov models for repairable systemsIntroduction and comparison of various RAID memory systemsThe architecture and fault-tolerant principles of TANDEM and STRATUS non-stop computer systemsPractical and tutorial examples and numerous practice problemsAppendices which cover the necessary background material on probability, reliability, andarchitecture Reliability of Computer Systems and Networks offers in-depth and up-to-date coverage of reliability and availability for students with a focus on important applications areas, computer systems, and networks.

Network card - A network card (also called network adapter, network interface card, NIC, etc.) is a piece of computer hardware designed to allow computers to communicate over a computer network.

Network complexity - Network complexity is the number of nodes and alternative paths that exist within a computer network, as well as the variety of communication media, communications equipment, protocols, and hardware and software platforms found in the network.

Computer hardware - Computer hardware is the physical parts of a computer, as distinguished from the computer software or computer programs and data that operate within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data which are "soft" in the sense that they are readily created, modified or erased on the computer.

Packet sniffer - Packet sniffers (also known as network analyzers or Ethernet sniffers) are software programs (usually) or computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams back and forth over the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.
