Depending on its function, transmission speed, and application scenarios, network cards can be classified into various types. This article will provide a detailed explanation of different types of network cards and their application scenarios. 1. By function classification: (1) Ordinary network card: the most common network interface card, used to connect computers to local area networks (LAN). It supports basic network communication functions such as data transmission, reception, and sending. Ordinary network cards are widely used in daily network environments such as homes, schools, and enterprises. (2) Wireless network card: a device that allows a computer to connect to a network wirelessly. It does not require a physical cable connection and can be used anywhere with wireless network coverage. Wireless network cards are commonly used in mobile offices and public places for wireless network access. 2. By transmission speed classification:

(1) 100Mbps network card: a network card with a transmission speed of 100 Mbps, suitable for general network environments and application scenarios. It can meet the daily network needs of most homes and businesses.

(2) 1Gbps network card: a network card with a transmission speed of 1 Gbps, suitable for network environments and application scenarios that require high-speed data transmission, such as large enterprises, data centers, high-definition video transmission, etc. 3. By application scenario classification: (1) Desktop network card: a network card suitable for personal computers, with features such as small size, easy installation, and affordable price. It is widely used on computer equipment at home and in offices. (2) Server network card: a high-performance network card used for servers, with features such as high-speed transmission, good stability, and support for multiple ports. It is commonly used in large enterprises, data centers, and other application scenarios that require handling large amounts of data. 4. Other special types of network cards: fiber optic network cards and PCIe network cards which are introduced earlier in this article. In summary, different types of network cards have their own unique characteristics and application scenarios. Proper selection and use of network cards can help improve network performance and efficiency in various environments and scenarios.
