Opis

Coding is an highly integral component of viable and efficient computer and data communications, yet the often heavy mathematics that form the basis of coding can prevent a serious and practical understanding of this important area. "Coding for Data and Computer Communications" eschews the complex mathematics and clearly describes the core concepts, principles, and methods of channel codes ( for error correction), source codes (for compressing data), and secure codes (for cryptography, data hiding, and privacy). Conveniently organized and segmented into three associated parts for these coding types, the book examines the most important approaches and techniques used to make the storage and transmission of information (data) fast, secure, and reliable. Topics and features: *Integrates the disciplines of error control, data compression, and cryptography and data hiding *Presents material in a logical, clear, and lively way for rapid learning *Highly inclusive, balanced coverage for specialists and nonspecialists *Contains a chapter on the rarely covered topic of check digits *Provides numerous examples, illustrations, and other helpful learning aids An essential resource and monograph for all security researchers and professionals who need to understand and effectively use coding employed in computers and data communications. Anchored by a clear, nonmathematical exposition, the book presents all the major topics, principles, and methods in an accessible style suitable for professional specialists, nonspecialists, students, and individual self-study.

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.
