Today's networks are required to support an increasing array of real-time communication methods. Video chat, real-time messaging, and always-connected resources put demands on networks that were previously unimagined. The Second Edition of Fundamentals of Communications and Networking helps readers better understand today's networks and the way they support the evolving requirements of different types of organizations. It discusses the critical issues of designing a network that will meet an organization's performance needs and discusses how businesses use networks to solve business problems. Using numerous examples and exercises, this text incorporates hands-on activities to prepare readers to fully understand and design modern networks and their requirements. Key Features of the Second Edition: - Introduces network basics by describing how networks work - Discusses how networks support the increasing demands of advanced communications - Illustrates how to map the right technology to an organization's needs and business goals - Outlines how businesses use networks to solve business problems, both technically and operationally.
Learn how information theoretic approaches can inform the design of more secure information systems and networks with this expert guide. Covering theoretical models, analytical results, and the state of the art in research, it will be of interest to researchers, graduate students, and practitioners working in communications engineering.
"Information Systems for Business and Beyond introduces the concept of information systems, their use in business, and the larger impact they are having on our world."--BC Campus website.
This book sets out a systematic approach to making long-term choices about national infrastructure systems, for practitioners, policy-makers and academics.
Packed with diagrams and illustrations, Communications & Systems delivers plain-English explanations of all the technical fundamentals -- and puts everything in context by addressing standards, regulations, and the real-world outlook for legacy, contemporary, and emerging technologies. In this unique overview, Ray Horak lucidly describes today's communications systems and networks -- voice, data, video, and multimedia -- and explains how they are likely to evolve and converge as we move further toward an information-based economy. Whether you're a communications pro who wants to gain some perspective or you just want to understand our increasingly wired and wireless world, this is the one book you need to see the big picture, with just the right amount of detail.

This book highlights the most important research areas in Information and Communication Technologies as well as research in fields of telecommunication system characteristics at the physical level, deep discussion of telecommunication traffic and its performance indicators, studying of information systems technological parameters, review of public and special applications of information technologies. The book includes strictly selected results of the most interesting scientific research presented at the 10th International Conference “Infocommunications – Present and Future” (IPF’2020) that was held in Odesa, Ukraine. The respective chapters share in-depth and extended results in these areas with a view to resolving practically relevant and challenging issues including: 1. research of telecommunication system characteristics at the physical level: the discussion of various aspects of the signal transmission quality indicators analysis for solving practically important issues in telecommunication systems; 2. research of telecommunication traffic and its performance indicators: the significant aspects of research for forecasting of services characteristics of telecommunication systems; 3.research of information systems technological parameters: the discission of some effective technological solutions that can be used for the implementation of novel systems; 4. research of public and special applications of information technologies: the discussion of the various aspects of scientific and educational applications, etc. These results can be used in the implementation of novel systems and to promote the exchange of information in e-societies. Given its scope, the book offers a valuable resource for scientists, lecturers, specialists working at enterprises, graduate and undergraduate students who engage with problems in Information and Communication Technologies as well as Radio Electronics.
Addressing the fundamental technologies and theories associated with designing complex communications systems and networks, Principles of Communications Networks and Systems provides models and analytical methods for evaluating their performance. Including both the physical layer (digital transmission and modulation) and networking topics, the quality of service concepts belonging to the different layers of the protocol stack are interrelated to form a comprehensive picture. The book is designed to present the material in an accessible but rigorous manner. It jointly addresses networking and transmission aspects following a unified approach and using a bottom up style of presentation, starting from requirements on transmission links all the way up to the corresponding quality of service at network and application layers. The focus is on presenting the material in an integrated and systematic fashion so that students will have a clear view of all the principal aspects and of how they interconnect with each other. A comprehensive introduction to communications systems and networks, addressing both network and transmission topics Structured for effective learning, with basic principles and technologies being introduced before more advanced ones are explained Features examples of existing systems and recent standards as well as advanced digital modulation techniques such as CDMA and OFDM Contains tools to help the reader in the design and performance analysis of modern communications systems Provides problems at the end of each chapter, with answers on an accompanying website
