Definition and Function of Network Card: A network card, also known as a NIC card (Network Interface Card), is an active device that connects a computer to a network. Its main function is to receive and transmit data to achieve communication between networks. The Role of Network Cards in Network Products: 1. Connection Function: The network card is a key device for connecting computers to networks. Through the network card, computers can communicate with other computers or network devices to share resources and exchange information. 2. Data Transmission: The network card is responsible for receiving and sending data packets, which is an important part of data transmission. In a local area network, the network card exchanges data through devices such as hubs or switches to achieve network communication. 3. Signal Conversion: The network card is responsible for converting the data signal inside the computer into the electrical or optical signal for network transmission to adapt to different network transmission media and transmission rates. 4. Configuration of Network Parameters: The network card usually has the function of configuring network parameters, such as IP address, subnet mask, gateway, etc., which facilitates user network settings and management. The Importance of Network Cards in Network Products: 1. Improving Network Performance: The performance of the network card directly affects the performance of the entire network. High-quality network cards can provide higher data transmission rates and more stable network connections, thereby improving the overall performance of the network. 2. Ensuring Network Security: The network card has data encryption and security protection functions that can ensure the security of network communications and prevent data from being stolen or tampered with. 3. Simplifying Network Management: By configuring the parameters of the network card, it is possible to easily manage network devices and resources, simplifying the process of network management. 4. Expanding Network Applications: With the continuous expansion of network applications, the application of network cards in areas such as multimedia, cloud computing, and the Internet of Things is becoming more widespread, providing important support for the development of these areas.
