网卡是计算机与网络进行通信的接口设备，它负责将计算机与网络连接起来。根据不同的接口类型和传输速度，网卡可以分为多种类型。在购买网卡时，我们需要确保其与计算机的接口类型相匹配，并关注其传输速度和性能。 四、调制解调器（Modem） 调制解调器是连接计算机与电话线之间的设备，它负责将数字信号转换成能够通过电话线传输的信号。在宽带上网时代，调制解调器已经逐渐被光猫所取代，但仍然是一种常见的网络配件。 五、无线网卡 无线网卡是使计算机能够接收无线网络信号的设备。在无线通信日益普及的今天，无线网卡已经成为许多计算机的标配配件。在购买无线网卡时，我们需要关注其兼容性、传输速度和信号稳定性等指标。 六、集线器（Hub）和交换机（Switch） 集线器和交换机是用于连接多台计算机的网络设备。集线器将多台计算机的信号集中在一起进行传输，而交换机则能够根据目的地址进行智能传输，提高网络传输效率。在构建局域网时，我们需要根据实际需求选择合适的设备。 综上所述，这些网络产品的配件虽然看似普通，但在我们的生活和工作中却扮演着至关重要的角色。选择合适的配件能够提升我们的使用体验、保护设备以及增强网络稳定性等。因此，在购买和使用网络产品时，我们应该重视这些配件的选择和使用。 (以下为上述内容的英文翻译) An Introduction to the Essential Accessories for Network Products In today's digital age, network products have infiltrated every aspect of our lives. Whether for work, study, or entertainment, we cannot do without them. However, in addition to the network products themselves, there are also essential accessories that play a crucial role in enhancing our user experience, protecting equipment, and enhancing network stability. This article will introduce you to these network product accessories. First, network cables. Network cables are the infrastructure for connecting network devices, responsible for transmitting network signals from one device to another. Depending on the transmission speed and distance, network cables can be divided into various types such as Category 5 cables, Category 6 cables, and more. When purchasing network cables, we need to choose the appropriate type and specification based on actual needs. Second, routers. Routers are one of the core devices for network connections, responsible for distributing and forwarding network signals so that multiple devices can share network resources. When selecting a router, we need to pay attention to its coverage area, signal stability, and performance. Third, network interface cards (NICs). NICs are interface devices that allow computers to communicate with networks. They connect computers to networks. Depending on the interface type and transmission speed, NICs can be divided into various types. When purchasing a NIC, we need to ensure that it matches the interface type of the computer and pay attention to its transmission speed and performance. Fourth, modems. Modems are devices that connect computers to telephone lines, converting digital signals into signals that can be transmitted over telephone lines. In the era of broadband internet access, modems have gradually been replaced by optical modems, but they are still a common network accessory. Fifth, wireless network cards. Wireless network cards are devices that allow computers to receive wireless network signals. With the increasing popularity of wireless communication today, wireless network cards have become standard equipment in many computers. When purchasing a wireless network card, we need to pay attention to its compatibility, transmission speed, and signal stability.

Sixth, hubs and switches. Hubs and switches are network devices used to connect multiple computers. Hubs concentrate the signals of multiple computers for transmission, while switches can intelligently transmit based on the destination address to improve network transmission efficiency. When building a local area network (LAN), we need to choose the appropriate device based on actual
