网卡，也称为网络接口卡（NIC），是连接计算机和网络的重要设备。它允许计算机通过网络进行通信，包括发送和接收数据。网卡具有强大的数据处理能力，能够支持多种网络协议和标准，如以太网、Wi-Fi等。 二、集线器 集线器（Hub）是一种用于连接多台计算机的网络设备，它在网络中起到汇聚的作用。通过集线器，可以将多台计算机的网线集中连接在一起，形成一个共享的网络环境。集线器简单易用，成本低廉，因此在局域网中得到了广泛的应用。 三、中继器 中继器（Repeater）是一种网络连接设备，用于延长网络电缆的传输距离或增强信号强度。在网络传输过程中，信号会因为距离、干扰等因素而逐渐衰减，中继器可以在这些信号减弱的地方进行放大和再生，从而保证网络的稳定性和传输速度。 一网打尽：中文翻译 Take a comprehensive look at network accessories: network cards, hubs, and repeaters In computer networking, there are many essential hardware components, among which network cards, hubs, and repeaters are indispensable. These devices play a vital role in data transmission and network connectivity. Below we will take a comprehensive look at these three network accessories. First, network cards. Also known as network interface cards (NICs), network cards are crucial devices that connect computers to networks. They allow computers to communicate over the network by sending and receiving data. Network cards have powerful data processing capabilities and support various network protocols and standards such as Ethernet and Wi-Fi. Second, hubs. Hubs are networking devices used to connect multiple computers. They play a role in converging the network. By connecting the network cables of multiple computers together through a hub, a shared network environment can be formed. Hubs are simple to use and cost-effective, making them widely used in local area networks. Third, repeaters. Repeaters are network connection devices used to extend the transmission distance of network cables or enhance signal strength. During network transmission, signals can gradually fade due to factors such as distance and interference. Repeaters can amplify and regenerate these weakened signals, ensuring network stability and transmission speed.

In summary, network cards, hubs, and repeaters are essential network accessories that play a vital role in data transmission and network connectivity. Understanding their functions and applications can help us better utilize them to build a stable and efficient computer network.
