Among various network connection methods, wireless and wired connections are the most common ones. As the hardware device for network connection, the selection and comparison of network interface controllers (NICs) have become the focus of attention. This article will provide a detailed analysis and comparison of the types, performance, and usage scenarios of wireless and wired network interface controllers. II. Selection and Comparison of Wireless Network Interface Controllers: 1. Types: Wireless network interface controllers are mainly divided into built-in and external types. The built-in wireless network interface controller is usually integrated with the motherboard and needs to be selected when purchasing a computer. The external wireless network interface controller, on the other hand, exists in the form of USB or PCI-E interfaces, making it convenient for users to install and disassemble as needed. 2. Performance: The performance of a wireless network interface controller mainly depends on its transmission rate, coverage, and stability. Currently, the mainstream wireless network interface controllers on the market have transmission rates reaching gigabit levels, with relatively wide coverage that can meet the daily needs of most users. At the same time, with technological advancements, the stability of wireless network interface controllers has also been significantly improved. 3. Usage Scenarios: Wireless network interface controllers are suitable for scenarios without fixed network wiring, such as homes, cafes, libraries, and other public places. Additionally, for users who often need to work remotely, wireless network interface controllers are essential equipment. III. Selection and Comparison of Wired Network Interface Controllers:

1. Types: Wired network interface controllers are usually integrated with the motherboard and require no additional installation. However, with the development of technology, there are also USB-supported wired network interface controllers on the market, which facilitate users to switch between different devices.

2. Performance: The performance of a wired network interface controller is relatively stable, with high transmission rates and less interference from external factors. In scenarios such as high-speed data transmission and online gaming, the performance of a wired network interface controller is even more outstanding. 3. Usage Scenarios: Wired network interface controllers are suitable for scenarios that require a stable network connection, such as offices and schools in fixed locations. In these scenarios, connecting through an Ethernet cable ensures stability and high speed of the network connection. IV. Conclusion: Wireless and wired network interface controllers each have their advantages and disadvantages, and the
