Giáo trình Mạng máy tính và truyền thông (Ngành: Công nghệ kỹ thuật điện tử truyền thông - CĐ) - Trường Cao đẳng Công nghiệp Thanh Hóa

The rapidly evolving field of computer networks and communications is fundamental to modern society, influencing nearly every aspect of daily life from education to industry. This academic text, "Mạng máy tính và truyền thông," addresses the critical need for well-trained professionals capable of navigating and advancing within this dynamic landscape. Developed for students in Electrical and Electronic Communication Engineering at Thanh Hoa Industrial College, its primary objective is to provide a comprehensive and practically oriented foundation. It emphasizes the importance of understanding core concepts, historical developments, and current technological trends, thereby preparing students with essential knowledge and skills for their future careers.

Students and vocational technicians in Electrical and Electronic Communication Engineering, and professionals seeking foundational knowledge in computer networks and communications.

This academic module, titled "Mạng máy tính và truyền thông," provides a practical, up-to-date curriculum designed for vocational technicians in Electrical and Electronic Communication Engineering. It comprehensively covers the foundational aspects of computer networks and modern communication technologies, reflecting their profound impact across education, healthcare, and entertainment. The curriculum is structured into five key lessons, beginning with an introduction to network concepts and their historical evolution, highlighting pioneers like Vannevar Bush and the development of Hypertext/Hypermedia, and emphasizing the increasing ubiquity of multimedia. The module delves into core principles, including the various physical transmission media such as coaxial cable, twisted pair cable (detailing different types like UTP, FTP, S/FTP, and their performance categories up to Cat 8), and fiber optic cable. The discussion on fiber optics elaborates on its structure, signal transmission via light, and its advantages in terms of speed and stability, covering specific types like FTTH and various installation methods. Furthermore, it explores the wireless environment, charting the rapid advancements from 2G to 5G and discussing key wireless standards like Wi-Fi and Bluetooth. A significant portion is dedicated to computer network architecture, defining network topology (Star, Bus, Ring, Hierarchical, Hybrid) and network protocols (e.g., TCP/IP). The module also provides a detailed classification of networks based on geographical distance (LAN, MAN, WAN, GAN) and switching techniques (circuit, message, and packet switching). Finally, it introduces the functions and characteristics of network operating systems, including resource management and common examples. This structured approach aims to equip students with the necessary knowledge, skills, and professional responsibility to effectively design, implement, and maintain modern communication infrastructures.
