As a key device for network connection, the performance of network card directly affects the operation efficiency and stability of the entire network. Therefore, a deep understanding of network card technology is of great significance for network upgrades and optimizations. Overview of Network Card Technology: The network card, also known as the network interface card, is the bridge between the computer and the network. It converts the digital signals of the computer into network signals to achieve a connection between the computer and the network. Network card technology mainly involves technology in the physical layer and data link layer, including signal transmission, data encoding, network protocols, etc. Detailed Explanation of Network Card Technology: 1. Signal Transmission: The network card transmits signals through media such as copper wires or optical fibers. In the process of transmission, the network card needs to convert digital signals into electromagnetic signals for transmission on the network. At the same time, the network card also needs to encode and decode the transmitted signals to ensure their accuracy and reliability. 2. Data Encoding: To transmit data on the network, it needs to be encoded. The network card uses different encoding methods, such as Manchester encoding and differential encoding, to convert data into a format that can be transmitted on the network. 3. Network Protocols: The network card needs to follow certain network protocols, such as the TCP/IP protocol, to achieve connections and communications with the network. These protocols define standards for data transmission formats, transmission speeds, error detection, etc. Assisting Network Upgrade with Network Card Technology: With the continuous development of network technology, the requirements for network card technology are becoming higher and higher. To meet the growing needs of the network, we need to upgrade and optimize network card technology. Specific measures include: 1. Improving transmission speed: By adopting more advanced signal transmission technologies and encoding methods, we can increase the transmission speed of the network card to meet the needs of high-speed networks.

2. Enhancing stability: Optimizing the performance and design of the network card to improve its stability and reliability, ensuring the stability and security of network connections.
