Introduction With the continuous development of technology, the internet has become an integral part of our lives. Networking components play a crucial role in building and optimizing network systems. This article will provide a detailed introduction to the types, functions, and roles of various networking components in various network applications. II. Types of Networking Components 1. Transmission media: including twisted-pair cables, optical fibers, etc. Twisted-pair cables are commonly used for local area network connections, while optical fibers are widely used in wide area networks due to their high speed and long-distance transmission capabilities. 2. Network adapters: such as Ethernet cards, wireless network cards, etc. They are responsible for connecting computers to the network, enabling devices to transmit and receive data. 3. Switches: are network devices used to connect multiple computers and other network devices in a local area network. 4. Routers: are core devices for network connections, responsible for data transmission and routing between different networks in a wide area network. 5. Hubs: are used to connect multiple devices and expand the network. Hubs regenerate the received signal and broadcast it to all connected ports. 6. Modems: are data communication devices that convert digital signals into signals that can be transmitted over existing telephone lines or perform the reverse conversion.
