二、英文翻译 From Beginner to Expert: A Comprehensive Guide to Fundamental Networking Cables Knowledge In our daily life, network cables play a crucial role in connecting various devices in homes, schools, offices, and other venues. Therefore, it is essential for everyone to understand the fundamental knowledge of network cables. Below, we will provide a comprehensive overview of the basics, types, selection, and usage of network cables. 1. Definition and Role of Network Cables Network cables, also known as twisted-pair cables, are electronic wires used to transmit data. By twisting paired signal wires together with a certain twisting distance, they reduce electromagnetic interference and noise impact, thereby achieving efficient data transmission. In computer networks, network cables are responsible for connecting various network devices such as routers, switches, computers, etc., to achieve the purpose of network communication.

Network cables are mainly classified according to their purpose and transmission speed as follows: (1) Cat.5e (Enhanced Category 5): Primarily used for Gigabit network connections, with high transmission speed and stability. (2) Cat.6: Has a higher transmission frequency and longer transmission distance compared to Cat.5e, suitable for 10 Gigabit network connections. (3) Cat.7: With higher transmission speed and stronger anti-interference capabilities, it is suitable for high-speed network connections and special environmental network cabling. (4) Fiber optic cables: Using optical signals to transmit data, with advantages of fast transmission speed, long transmission distance, and strong anti-interference capabilities. Often used for long-distance network connections or high-speed network environments. 3. Selection and Usage of Network Cables: (1) Selecting the appropriate type of network cable: Choose the right type of network cable based on actual needs; for example, homes and small enterprises typically choose Cat.5e or Cat.6 cables for their networks. (2) Examining cable quality: When purchasing network cables, check their quality, brand, specifications, and other parameters to ensure that you are purchasing a cable that meets the required standards. (3) Properly connecting network cables: Ensure that the wiring order is correct and the interface is secure during the connection process to avoid network connection issues. (4) Maintenance and care: Regularly inspect the connection status of the network cables, replace damaged cables promptly, and maintain the stability and reliability of the network connection.
