五、网络配件知识科普（英文版） Introduction to Networking Components: From Beginner to Expert Basic Knowledge of Networking Components: Network components are an important part of computer networks, including various network devices, transmission media, and network interfaces. To better understand and apply network components, we need to first grasp some basic knowledge. Common Network Components: 1. Router: A device that connects multiple networks or networks, with the function of network-level interconnection. It can route and forward data packets based on network-level information to the destination. 2. Switch: A device used to connect multiple computers or network equipment, which can exchange and forward data frames to achieve local area network communication. 3. Hub: A centralized shared-media network device that can connect multiple computers together to achieve resource sharing and data transmission.

4. Network Card: An internal expansion card of a computer that is responsible for connecting the computer to the network to achieve communication with other computers.

Application and Selection of Network Components: When selecting network components, we need to consider actual needs and budgets comprehensively. Here are some suggestions for application and selection: 1. Select appropriate network devices and transmission media based on actual needs. If high-speed and stable data transmission is required, fiber optic cables and high-end routers can be selected. 2. Choose the right network card. The model and brand of the network card need to be compatible with the computer's hardware and operating system to ensure the stability and performance of the network connection. 3. Pay attention to the compatibility and scalability of network components. When purchasing network components, consider their compatibility with other devices and systems, as well as future scalability. 4. Regularly maintain and inspect network components. Regular inspection and maintenance of network components can ensure their normal operation and extend their service life. Common Problems and Solutions of Network Components: During the use of the network, some common problems may occur, such as unstable network connection, slow data transmission speed, etc. Here are some solutions to common problems: 1. Unstable network connection: It may be caused by loose network cables or network equipment failures. At this time, it is necessary to check the connection of network cables and the status of network equipment, and replace or repair them in
