Features: This book is a comprehensive and systematic textbook on the fundamentals of computer networks, covering the architecture of computer networks, communication protocols, and related technologies in detail. The book is divided into 9 chapters. The first 3 chapters comprehensively introduce relevant theories and technologies from three perspectives: the overall computer network, computer local area networks (LANs), and computer wide area networks (WANs). The following 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 remaining 5 chapters cover the other 5 layers of the OSI 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 theories of various aspects of computer networks but also gain an in-depth understanding of the OSI seven-layer reference model of computer networks, as well as the basis for its division, working principles, and primary functions. This book is particularly suitable for self-study by network administrators and network engineers, and it can also serve as a training textbook for those preparing for various network administrator and network engineer soft exam qualifications. 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 suitable as a reference textbook for colleges, universities, and training institutions.
