Network cables, also known as Ethernet cables, are critical elements for connecting network devices and transmitting data. They transmit information through electromagnetic waves, enabling communication between computers and other devices. Types: There are several types of network cables, including twisted-pair cables, coaxial cables, and fiber-optic cables. Twisted-pair cables are widely used due to their low cost and good transmission performance. Applications: Network cables are primarily used to connect devices in a local area network (LAN), such as computers, printers, servers, etc. These devices can communicate with each other and share resources through network cables. Two, Routers Routers are key devices used to connect multiple networks or subnets in a network. They forward and route data packets based on network layer addressing information. Functions: The main functions of routers include data packet forwarding, network address resolution, and routing table generation. They can select the optimal path for data transmission based on different requirements. Applications: Routers are widely used to connect between LANs and WANs. They also provide stable and efficient network connection services within homes or businesses. Three, Switches Switches are devices used for multi-port communication within a LAN. They forward data packets to the appropriate ports based on different data link layer information. Types: Switches include Ethernet switches, fiber-optic switches, etc. Ethernet switches are preferred due to their low cost and widespread application. Functions: The main functions of switches include data packet forwarding, communication between ports, and division of broadcast domains. They can improve the transmission speed and efficiency of a LAN and reduce the likelihood of network congestion. 综上所述，网线、路由器和交换机是构建和维护网络系统不可或缺的配件。它们各自具有独特的功能和应用场景，共同构成了现代网络的基石。
