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.

Computer communications is characterized by rapid technological advances presenting problems of a theoretical nature that are often very difficult to solve. This title constitutes the proceedings of the 1983 AMS Short Course given at Denver, Colorado. It features contributors from a variety of different fields of computer communications.

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

For anyone required to design, develop, implement, market, or procure products based on specific network security standards, this book identifies and explains all the modern standardized methods of achieving network security in both TCP/IP and OSI environments--with a focus on inter-system, as opposed to intra-system, security functions.

Computer communications is one of the most rapidly developing technologies and it is a subject with which everyone in the computer systems profession should be familiar. Computer communications and networks is an introduction to communications technology and system design for practising and aspiring computer professionals. The subject is described from the computer system designer's point of view rather than from the communications engineer's viewpoint. The presentation is suitable for introductory reading as well as for reference. The emphasis is on practical, rather than theoretical, aspects and on technology which will become more important in the future. The majority of the subject matter applies to civil and military communications but some aspects which are unique to military applications have been included where considered signifi cant. Computer communications is a rapidly changing and highly complex subject. Sufficient practical knowledge of the subject is not usually gained at university or college but is generally developed over a period of several years by trial and error, attending courses, reading reference books and journals; this book attempts to simplify and speed up the process by bringing together a body of information which is otherwise distributed throughout many books and journals. The information is presented in a framework which makes a wider understanding of the subject possible. Basic knowledge of communications is assumed, a general famil iarity with computer systems is anticipated in later chapters, and, where relevant, theory is explained.

This timely textbook presents a comprehensive guide to the core topics in computing and information security and assurance realms, going beyond the security of networks to the ubiquitous mobile communications and online social networks that have become part of daily life. In the context of growing human dependence on a digital ecosystem, this book stresses the importance of security awareness—whether in homes, businesses, or public spaces. It also embraces the new and more agile and artificial-intelligence-boosted computing systems models, online social networks, and virtual platforms that are interweaving and fueling growth of an ecosystem of intelligent digital and associated social networks. This fully updated edition features new material on new and developing artificial intelligence models across all computing security systems spheres, blockchain technology, and the metaverse, leading toward security systems virtualizations. Topics and features: Explores the range of risks and vulnerabilities in all connected digital systems Presents exercises of varying levels of difficulty at the end of each chapter, and concludes with a diverse selection of practical projects Describes the fundamentals of traditional computer network security, and common threats to security Discusses the role and challenges of artificial intelligence in advancing the security of computing systems’ algorithms, protocols, and best practices Raises thought-provoking questions regarding legislative, legal, social, technical, and ethical challenges, such as the tension between privacy and security Offers supplementary material for students and instructors at an associated website, including slides, additional projects, and syllabus suggestions This important textbook/reference is an invaluable resource for students of computer science, engineering, and information management, as well as for practitioners working in data- and information-intensive industries. Professor Joseph Migga Kizza is a professor, former Head of the Department of Computer Science and Engineering, and a former Director of the UTC InfoSec Center, at the University of Tennessee at Chattanooga, USA.
