Foundations of Computer Networks: Principles, Models, and Algorithms of Digital Communication

Computer networks form the foundation of the modern digital world. They connect information systems and make the exchange of data possible on which modern communication and information services depend. This textbook approaches computer networks from a principles-oriented perspective. Rather than presenting a collection of individual protocols and technologies, it examines the fundamental problems of digital communication and the models, algorithms, and architectural concepts used to solve them. Mathematical ideas and systematic models provide a foundation for understanding how networks are structured, how information is transmitted, how communication can be made reliable, and how complex systems can coordinate their activities. The book also addresses network security, distributed communication, adaptive networks, artificial intelligence, and emerging forms of communication. The focus throughout is not on rapidly changing technologies, but on the underlying principles that remain relevant across different generations of network systems. Numerous exercises with detailed solutions encourage readers to deepen their understanding and apply the concepts independently. Written for students of computer science and related disciplines, this book is also suitable for readers who want to understand computer networks at a fundamental level and gain a coherent view of the principles behind modern digital communication. Technologies change. Principles remain.
