无线网卡是一种可以让计算机或其他设备通过无线网络连接到互联网的配件。无线网卡通常内置在笔记本电脑中，也可以作为外置设备使用。 2. 光纤收发器（Fiber Optic Transceiver） 光纤收发器是一种将光信号转换为电信号或将电信号转换为光信号的设备。它广泛应用于长距离的光纤通信网络中，具有高速、稳定、抗干扰等优点。 Network Accessories Knowledge Popularization: From Beginner to Expert Part 1: Beginner's Introduction In the world of networking, network accessories are the bridges connecting various devices and services. They play a crucial role in maintaining the smooth operation of a network. With a wide range of types, from the most basic network cables and hubs to complex routers and switches, each has its own purpose and characteristics. Below, we will briefly introduce the basic knowledge of network accessories. 1. Network Cable Network cable is one of the most basic network accessories, mainly used to connect computers, switches, routers, and other devices. Depending on the transmission speed and purpose, network cables are divided into twisted-pair cables, coaxial cables, and optical fibers. 2. Hub (Hub) Hub is a network device that concentrates the network cables of multiple computers together to form a local area network (LAN). The main function of the hub is to expand the network coverage and improve the transmission efficiency of the network. Part 2: Advanced Understanding After understanding the basic network accessories, we need to further explore more complex network devices.

1. Router (Router)

Router is one of the core devices for network connection. It is responsible for transmitting data packets from the source address to the destination address. With multiple ports, routers can connect multiple network devices to achieve interconnection between different networks. 2. Switch (Switch) Switch is a network device used for data exchange within a local area network (LAN). Different from routers, switches can forward data based on its MAC address, achieving high-speed and efficient data transmission. Part 3: Expert Knowledge To master the knowledge of network accessories, we need to understand more advanced concepts and technologies. 1. Wireless Network Card (Wireless Card) Wireless network card is a component that allows computers or other devices to connect to the Internet through wireless networks. Wireless network cards are usually built into laptops, but can also be used as external devices. 2. Fiber Optic Transceiver (Fiber Optic Transceiver) Fiber optic transceiver is a device that converts optical signals into electrical signals or electrical signals into optical signals. It is widely used in long-distance fiber-optic communication networks, with advantages of high speed, stability, and anti-interference.
