Types:

In network products, network cards are important hardware devices that connect computers to the network. Depending on different interface types, transmission speeds, and application scenarios, network cards can be divided into multiple types. Common types of network cards include the following:

1. wired network cards: connected to the network through wired connections, commonly used in fixed locations such as offices, schools, and homes. Wired network cards are generally connected to network cables through RJ45 interfaces and have stable transmission speeds and reliability.

2. wireless network cards: connect to the network through wireless signals without the need for cables. Wireless network cards are widely used in mobile devices, laptops, and certain specific application scenarios, such as wireless network meetings. 3. integrated network cards: integrated onto the motherboard and usually do not require additional installation. Integrated network cards have a relatively low price and are suitable for ordinary and home users. 4. fiber optic network cards: used for high-speed fiber optic network connections, suitable for large enterprises, data centers, and other scenarios that require high-speed, large-capacity transmission. Functions: As an important device for network connection, network cards have multiple functions. The main functions of network cards are as follows: 1. Data transmission: network cards are responsible for transmitting data from a computer to the network and receiving data transmitted from the network and transferring it to the computer. 2. Address recognition: network cards have unique physical addresses (MAC addresses) that are used to identify and locate computers in a network. 3. Network connection: connect to the network through wired or wireless methods to achieve interconnection between the computer and the network. 4. Error detection: during data transmission, the network card can detect and process data transmission errors. 5. Data processing: process received data, such as packet fragmentation, assembly, etc. In summary, there are various common types and functions of network cards in network products. Different types of network cards are suitable for different application scenarios and needs. Understanding the types and functions of network cards can help better choose a network device that meets your needs.
