网线常见的连接方式包括直通线（直连线）和交叉线两种。直通线主要用于连接计算机和交换机，而交叉线则用于连接两台计算机。 三、网线的应用与维护 1. 网线的应用场景 网线广泛应用于局域网的建设和家庭网络的建设中，可以满足日常的数据传输需求。 2. 网线的维护与保养 网线需要定期进行检测和维护，避免因老化或损坏而影响网络性能。同时，在安装和使用过程中，需要注意避免过度弯曲或拉扯，以免损坏网线。 四、网络产品的相关知识翻译成英文： A Comprehensive Guide to Network Cables in Network Products from Beginner to Expert I. Basic Knowledge of Network Cables 1. Basic Concepts of Network Cables Network cables, also known as twisted-pair cables, are cables used to transmit data. They are usually composed of eight thin wires divided into four pairs, with each pair twisted to reduce electromagnetic interference. 2. Types of Network Cables

Network cables are mainly classified into several types based on their transmission speed and purpose, including Category 5e, Category 6, Category 7, and fiber optic cables. Among them, Category 5e and Category 6 cables are the most commonly used.

II. Use and Selection of Network Cables 1. Selecting Suitable Network Cables When selecting network cables, it is necessary to consider factors such as the distance between network devices, speed requirements, and whether resistance to interference is needed to determine the type of cable to use. 2. Connection Methods of Network Cables Common connection methods for network cables include straight-through cables (UTP) and cross-over cables. Straight-through cables are mainly used to connect computers and switches, while cross-over cables are used to connect two computers. III. Application and Maintenance of Network Cables 1. Application Scenarios of Network Cables Network cables are widely used in the construction of local area networks and home networks, meeting daily data transmission needs. 2. Maintenance and Care of Network Cables Network cables need to be regularly inspected and maintained to avoid affecting network performance due to aging or damage. In the process of installation and use, attention should be paid to avoiding excessive bending or pulling to prevent damage to the cable. 以上内容仅供参考，具体内容需要根据您的需求进行调整优化。
