I. Network Card Performance Indicators The performance indicators of network cards mainly include the following aspects: 1. Transmission rate: The transmission rate of a network card refers to the amount of data that can be transmitted per second, usually measured in Mbps (megabits per second) or Gbps (gigabits per second). The higher the transmission rate, the faster the network connection speed. 2. Port type: The port types of network cards include PCIe, USB, RJ45, etc. Different types of ports are suitable for different devices and interfaces, so selection should be based on actual needs. 3. Compatibility: The compatibility of a network card refers to its compatibility with the operating system, motherboard, and other hardware. Choosing a network card with good compatibility can avoid network problems caused by incompatibility. 4. Signal quality: The signal quality of a network card determines the stability and transmission speed of the network connection. A good network card can better maintain signal stability and quality during transmission. 5. Functional features: Different network cards have different functional features, such as dual-band support, intelligent recognition, signal amplification, etc. These features can meet the needs of different users. II. Network Card Purchasing Guide When purchasing a network card, it is necessary to choose based on your actual needs and budget. Here are some tips for purchasing: 1. Determine your needs: First, determine your needs, such as transmission rate, port type, functional features, etc. If you need to connect to a high-speed network or use special features, you need to choose the corresponding network card accordingly. 2. Learn about brands and models: There are many brands and models of network cards available on the market. You can learn about products from well-known brands and compare the performance and price of different models. 3. Pay attention to compatibility: When choosing a network card, pay attention to its compatibility with the operating system, motherboard, and other hardware. If you choose an incompatible network card, it may cause network problems or cannot be used normally. 4. Consider signal quality: Signal quality is very important for the stability and speed of network connections. Therefore, when choosing a network card, consider whether its signal quality is stable and reliable. 5. Refer to user reviews: You can refer to other user reviews and feedback before purchasing to understand the advantages and disadvantages of the product and its actual use effect. 6. Price and cost-effectiveness: When considering price, also pay attention to the cost-effectiveness of the product. Don't just pursue low prices while ignoring product performance and quality.
