Overview of network card The network card, also known as a network adapter or Network Interface Card (NIC), is the bridge between the computer and the network. It allows computers to transmit and receive data to other devices on the network through wired or wireless signals. The network card in network products is one of the key devices connecting computers and local area networks. 2. Functions of network card a. Data transmission: The network card transmits data to the network through wired or wireless methods and is also responsible for receiving data from other devices. b. Signal conversion: The network card can convert digital signals into electromagnetic signals and transmit them through transmission media such as network cables or optical fibers. c. Network configuration: The network card has automatic configuration functions that can automatically set IP addresses, subnet masks, and other parameters based on the network environment. d. Compatibility: Different models of network cards can support different network standards and protocols, such as Ethernet, Wi-Fi, etc. 3. Types of network cards According to different classification standards, network cards can be divided into the following categories: a. By transmission method: wired network cards and wireless network cards. b. By interface type: PCIe network cards, USB network cards, etc. c. By supported network standards: Gigabit network cards, hundred-megabit network cards, etc.

The steps for installing and using a network card are roughly as follows: a. Determine the type of network card interface on the computer and the model of the network card that needs to be purchased. b. Insert the network card into the computer's interface or use a USB cable to connect it. c. Install drivers and software according to needs and complete the configuration of the network card. d. Test whether the network connection is normal. 5. Maintenance and troubleshooting of network cards To maintain and troubleshoot a network card, the following points should be noted: a. Regularly clean the dust and debris from the network card to maintain its good cooling performance. b. Regularly check the connection status of the network card to ensure that it is connected to the computer stably and reliably. c. If a problem occurs, first check whether the drivers and software are installed correctly and whether the computer's network settings are correct. If the problem remains unsolved, it is recommended to seek help from a professional person.
