Features: This book is a comprehensive and systematic textbook on the fundamentals of computer networks, covering the structure of computer networks, communication protocols, and related technologies in detail. The book is divided into 9 chapters. The first 3 chapters comprehensively introduce relevant theoretical knowledge and technologies from three perspectives: the overall computer network, computer local area networks (LANs), and computer wide area networks (WANs). The subsequent 6 chapters systematically present the OSI seven-layer reference model in ascending order from the lower to the higher layers. In addition to Chapter 8, which introduces the "Session Layer" and "Presentation Layer" of the OSI reference model, the other 5 chapters each cover the remaining 5 layers of the model, providing a thorough introduction to the main functions, communication protocols, service primitives, and network devices of each layer. Through studying this book, readers can not only systematically learn the fundamental theoretical knowledge of computer networks but also gain an in-depth understanding of the OSI seven-layer reference model, its basis for division, working principles, and primary functions. This book is particularly suitable for self-study by network administrators and network engineers, as well as serving as a training textbook for those preparing for various network administrator and network engineer soft exam certifications. The book is rich in content, covers a broad scope of knowledge, and provides an in-depth and professional introduction to principles and protocols, making it also an excellent reference textbook for colleges, universities, and training institutions.
