Introduction: In today's digital and networked era, the selection of network products and accessories is crucial for ensuring network performance and user experience. This article will provide a detailed explanation of how to select common network products and accessories, including routers, switches, network cards, etc., to help you make informed choices in the market. Part Two: Routers 1. Wireless Standard: When selecting a router, consider its wireless standard, such as 802.11n, 802.11ac, or the latest 802.11ax, etc. The higher the wireless standard, the faster the transmission speed and the broader coverage. 2. Frequency Band: Dual-band routers support both 2.4GHz and 5GHz frequency bands, which can effectively avoid interference and improve network stability. 3. Performance Parameters: Pay attention to the throughput and concurrent user capacity of the router to ensure it meets household or enterprise needs. 4. Function and Security: Consider features such as firewall, VPN support, parental control, etc., to ensure network security and household management needs. Part Three: Switches 1. Port Number and Type: Select a switch with an appropriate number and type of ports based on actual needs, such as Gigabit or 10 Gigabit ports. 2. Expandability: Choose a switch with high expandability for future upgrades and expansion of network equipment. 3. Performance and Power Consumption: Pay attention to performance parameters such as forwarding rate and power consumption to ensure stable equipment operation. Part Four: Network Cards 1. Interface Type: Select an appropriate network card based on the interface type of the computer or device, such as PCI-E, USB, etc. 2. Transmission Rate: Choose a network card with a high transmission rate to meet high-speed network transmission needs. 3. Compatibility: Ensure compatibility between the network card and the computer or device to avoid incompatibility issues. Part Five: Other Considerations 1. Brand and After-sales Service: Choose products from well-known brands and pay attention to after-sales service quality to ensure that the purchased products are supported and guaranteed. 2. Price and Performance: Select a suitable product based on your needs and budget, avoiding blind pursuit of high performance while ignoring price factors. 3. Testing and Debugging: Perform necessary testing and debugging after purchase to ensure the normal operation of the network products and accessories.
