Features: In the 21st century, computer technology has become an important foundation for promoting rapid socio-economic development and represents the era of the knowledge economy. While secondary vocational schools train qualified technical talents, they must also emphasize computer technology education. This not only helps improve students' basic cultural literacy but also provides them with the necessary tools for learning other subjects. This textbook is designed for secondary vocational schools and is based on the "Teaching Guidance for Network Technology Basics in the Computer and Application Specialty of Secondary Vocational Schools" issued by the Ministry of Education in 2001. According to the training objectives of secondary vocational education, the teaching task of this course is to enable students to understand and master the basic knowledge and skills of computer networks, develop the ability to apply computer networks, improve their scientific and cultural literacy, cultivate a spirit of teamwork, and meet the basic requirements for training high-quality laborers and junior and intermediate specialized talents. At the same time, it lays a foundation for students to use computers to learn other subjects and develops their preliminary ability to further study related professional knowledge using computers; it also fosters a scientific attitude and intellectual property awareness, encouraging them to engage in information technology activities in accordance with the law. This textbook is primarily aimed at students in secondary vocational schools. In terms of content selection, it focuses on introducing the basic knowledge, fundamental principles, and practical applications of computer network technology, emphasizing the clarification of the basic concepts, important theories, and practical applications of computer network technology while avoiding overly complex theoretical explanations. The narrative is designed to be as easy to understand as possible, with the student as the central focus in the arrangement of teaching content. The book is divided into 10 chapters, covering main topics such as the basics of computer networks and data communication, the main organizational methods and hierarchical structure of networks, the structure, characteristics, and setup methods of local area networks, the basics and applications of the Internet, the basic framework, principles, and content of network management, the basic system and related technologies of network security, and the network functions of the commonly used Windows 2000 operating system. Each chapter is accompanied by corresponding exercises to help students reinforce the content. For teaching convenience, representative examples are provided for each chapter to consolidate theoretical knowledge, combined with experimental teaching to cultivate students' innovative abilities, and closely integrate theory with practice. The book is arranged in a progressive manner following the cognitive patterns of beginners. For dry and tedious professional knowledge, such as computer technology terms, terminology, and concepts, we established the principle of permeating basic knowledge and using examples and illustrations interactively for explanation. During the writing process, we strictly adhered to the policy of "starting from practicality, incorporating a large number of illustrations, and motivating students' learning enthusiasm as the foundation." Reviewers have fully affirmed the writing philosophy, content selection, and writing style of this textbook. Experts believe, "The textbook meets the requirements of the teaching guidance in terms of content selection and length, and has made reasonable adjustments and explorations in the selection and arrangement of teaching content, making it more suitable for the characteristics and teaching realities of secondary vocational school students."
