Features: In the knowledge-based economy of the 21st century, the information industry will become the fastest-growing and largest industry in the social economy. Computer networks were born to meet the objective needs of the information society, emerging alongside the highly developed and integrated computer and communication technologies. With the rapid development and widespread adoption of computer network technology (especially Internet technology), its applications have permeated all aspects of social work and life, bringing profound historical changes to human lifestyles, ways of thinking, and concepts of time and space. Therefore, there is an urgent need for a large number of professionals skilled in the basic knowledge and application technologies of computer networks. This book is a practical textbook on network technology and its engineering practices, covering all aspects of network principles and applications, including the OSI reference model, network protocols, network architecture, network hardware, LANs/MANs/WANs, Internet/Intranet/Extranet, network security technologies, network planning and design, network operating systems, etc. The book adopts a "problem-oriented" structure, integrating theory and practice while maintaining the rigor and completeness of the theoretical system. It is highly contemporary, with structured cabling, VLANs, VPNs, third-layer switching, broadband IP networks, and network security representing the new trends in the development of computer networks. This book is the culmination of the author's long-term experience in teaching and engineering practice in computer networks. It can not only serve as a teaching material for university-level computer network courses but also be used for training or self-study by network engineering technicians.
