Coding For Data And Computer Communications

Digital data is heavily used when generating, storing, and transmitting information, and special codes are used to represent the data and to control its size, reliability, and security. Data coding is therefore a highly important, and indeed increasingly critical, discipline for data and computer communications. In a unique, single volume, this highly versatile text/reference introduces readers to the importance of channel coding (error-correcting codes), secure coding (cryptography), and source coding (data compression). It is organized in three main parts and uses clear, nonmathematical explanations to develop the concepts, principles, and techniques in each area of coding. Requiring only a general familiarity with computer methods, the book deals with all aspects of coding and its relevance to fast, secure, and reliable data transmission and storage. Features & Benefits: *Presents comprehensive coverage of areas of coding often found in separate books, and stresses data coding's relevance in today's world *Provides a wealth of examples and exercises (with solutions) to help readers easily grasp the material *Incorporates an extensive chapter on data hiding, a sparsely documented topic of increasing importance in the community *Includes an author-supplied website with supplementary material *Possesses a detailed bibliography and helpful glossary, index, and appendixes (including projects for self-study). Computer scientists, electrical engineers, and other professionals will find this up-to-date, accessible volume an essential resource about key areas, problems, and methods associated with data coding. Its straightforward approach also makes it very suitable for students taking courses on computer networks, coding and encryption, data communications, and information theory and coding. David Salomon is a professor emeritus of computer science at California State University, Northridge. He has authored numerous articles and books, including Data Compression: The Complete Reference (Third Edition), Guide to Data Compression Methods, and Data Privacy and Security, and Computer Graphics and Geometric Modeling. Key Topics:” Error-control codes” Image compression methods” Cipher types” Public-key cryptography” Check digits” Error detection” Statistical methods of source coding” Steganography (data hiding)” Encryption codes” Security / Cryptography” Beginning / Intermediate.

Details the most important techniques used to make the storage and transmission of data fast, secure, and reliable. Accessible to both specialists and nonspecialists: Avoids complex mathematics

The protocols and standards for networking are numerous and complex. Multivendor internetworking, crucial to present day users, requires a grasp of these protocols and standards. Data and Computer Communications: Networking and Internetworking, a comprehensive text/reference, brings clarity to all of the complex issues involved in networking activi

The subject of computer communications is changing very rapidly. Improvements in terminal access, aligned with the development of timesharing, has brought hands-on experience to a large number of non specialist users. Computer networks have made available vast computing resources and data banks to these users. This book is for anyone familiar with using computers who wishes to understand the techniques used in computer communications. It is also an introduction to the architecture of present day computer communication systems. I would like to thank Roland lbbett, Steve Treadwell, Peter Kirstein and Del Thomas for their invaluable advice and encouragement. My thanks also to Malcolm Stewart and the staff at Macmillan. The late Gareth Pugh encouraged my interest in computer communications and provided the opportunity to develop the material for this book. The text was formatted on a UNIX computer system: I am grateful to Professor Kirstein for permission to use this system. I am indebted to NEC Telecommunications Europe for the use of a spinwriter printer on which the master copy was produced. Finally, no amount of words can express my debt to Jo this project and Rosemary for patiently bearing with over the last three years.

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.

Now in its third edition, Computer Communications is a comprehensive introduction to digital communications. It includes full up-to-date coverage of subjects such as local and wide area networks and integrated services digital network. New material on standards, protocols, and network management has been added. 152 illus.
