The router is the main connecting device in a network, responsible for forwarding data between multiple networks. It processes and forwards data according to preset routing rules, routing data packets with different destinations to the appropriate ports and next network nodes. Third, Switch The switch is the core device of a local area network, with the main function of rapidly and efficiently forwarding data between multiple devices. Switches work by learning the MAC addresses of each device and storing them in memory, allowing them to accurately forward data packets to their destinations. Fourth, Modem A modem is a device used to connect a computer to a telephone line. It converts digital signals into analog signals that can be transmitted over the telephone line, and vice versa. Fifth, Wireless Access Point (AP) The Wireless Access Point (AP) is the core device of a wireless network, allowing wireless devices such as mobile phones and laptops to connect to the network. APs cover a certain area by broadcasting wireless signals, allowing devices to freely access the network within that area. Sixth, Fiber Optic Transceiver A fiber optic transceiver is a hardware device used for fiber optic communication. It converts electrical signals into optical signals or optical signals into electrical signals for transmission over fiber optic cables. Fiber optic transceivers play an important role in long-distance network communications. In conclusion, the above are several common components in a network, each with its unique functions and roles in constructing an efficient network system.
