四、网线 网线是连接各种网络设备的物理介质，负责传输数据信号。常见的网线有双绞线、同轴电缆和光纤等。网线的质量和长度都会影响网络的传输速度和稳定性。因此，在选择网线时，需要根据实际需求进行选择。 五、无线接入点（AP） 无线接入点是构建无线网络的关键设备，它能够将有线网络转换为无线网络，为移动设备提供无线接入服务。无线接入点具有信号放大和覆盖范围扩大的功能，可以保证无线网络的稳定性和传输速度。 **The Five Network Components That Cannot Be Ignored: Do You Know Their Functions?** In the digital age, the internet has deeply penetrated into every aspect of our lives. To ensure smooth operation and high performance of the network, five major network components play a crucial role. They are not only the foundation of network construction but also the key to maintaining network stability and security. Below, we will analyze each of these five network components and their functions. First, the router. The router is the core of a household or business network, connecting the internal network with the external network. It can transmit data packets from the source address to the destination address based on routing information at the network layer. With IP addressing functions, routers effectively allocate IP addresses to ensure normal communication between devices within the network. Additionally, routers also have firewall functions that protect the internal network from external attacks.

Second, the switch. The switch is an important device within a local area network, connecting multiple computers and other network devices. It achieves rapid data forwarding through the MAC address table, improving the transmission efficiency of the network. Switches can expand the coverage of the network while also isolating collision domains and reducing the occurrence of network failures.

Third, the network interface card (NIC). The NIC is a bridge between a computer and the network, responsible for converting computer data into a format that can be transmitted on the network. It also has functions at the data link layer, handling the transmission and reception of data frames. The quality and performance of the NIC directly affect the internet speed and network stability of a computer. Fourth, the network cable. The network cable is the physical medium connecting various network devices, responsible for transmitting data signals. Common network cables include twisted-pair cables, coaxial cables, and fiber-optic cables. The quality and length of a network cable can affect its transmission speed and stability. Therefore, when selecting a network cable, it is necessary to make a choice based on actual needs. Lastly, wireless access points (AP). Wireless access points are key devices for building wireless networks, converting wired networks into wireless networks and providing wireless access services for mobile devices. Wireless access points have functions such as signal amplification and expanding coverage to ensure wireless network stability and transmission speed.
