2. Network Interface Cards (NICs) NICs are the bridge between a computer and the network, responsible for connecting the computer to the network. When selecting a NIC, pay attention to its interface type (such as RJ45, fiber-optic interface) and transmission speed parameters. Stage Two: Understanding Different Product Features and Performance After understanding the basic concepts, we need to further explore the features and performance of different products. This will help us choose network components that better suit our needs. 1. Routers Routers are key devices in a network, responsible for interconnecting different networks. When selecting a router, consider its coverage area, number of ports, processor performance, and other parameters. Additionally, pay attention to the brand and reputation of the router. 2. Switches Switches are used to connect multiple computers or other network devices, enabling data exchange within a local area network. When choosing a switch, consider its port types (such as electrical ports, optical ports), bandwidth, and other parameters. Stage Three: Purchasing Based on Actual Needs After understanding the basic concepts and product features, we need to make purchases based on actual needs. Here are some tips for purchasing networking components: 1. Determine Your Needs: Before purchasing, clarify your needs. For example, how many devices do you need to connect? What are your transmission speed requirements? What are your expectations for device scalability? 2. Budget: Set a budget based on your needs and avoid blindly pursuing high configurations or low prices. When selecting products, consider performance and price factors comprehensively. 3. Brand and After-sales Service: Choosing products from a reputable brand ensures quality and service. Pay attention to the after-sales service of the product, such as warranty period, return and exchange policy.
