Types of Network Interface Cards and Their Application Scenarios First, the interpretation of various types of network interface cards (NICs). NICs are the interface devices for computers to communicate with the network. Based on their functions and uses, NICs can be divided into different types. 1. Wired NICs: The most common type of NIC, wired NICs connect computers to local or wide area networks through RJ45 interfaces and cables. They are available in different speeds such as 10M, 100M, and 1G. 2. Wireless NICs: These NICs communicate with the network through wireless signals, eliminating the need for cables. They are suitable for locations where wiring is not possible or for mobile usage scenarios. Different wireless standards such as 802.11n, 802.11ac, and 802.11ax are supported by different wireless NICs. 3. Fiber Optic NICs: These NICs achieve high-speed data transmission through fiber optic cables. They are typically used in high-bandwidth demand scenarios such as data centers and large corporate networks. Second, the application scenarios of various types of NICs: 1. Wired NICs are commonly used in enterprise office networks, school campus networks, and home networks due to their stability and high transmission speed. They provide a stable network connection and high-speed data transmission in these scenarios. 2. Wireless NICs are suitable for locations where wiring is not possible or for mobile usage such as public Wi-Fi networks in cafes, airports, and hotels, as well as wireless network connections for personal laptops and other devices. 3. Fiber Optic NICs are mainly used in high-bandwidth demand scenarios such as data centers and large corporate networks. They provide high-speed and stable data transmission and large-scale network connectivity in these scenarios. Additionally, they are widely used in scenarios that require large bandwidth and low latency such as video conferencing and multimedia transmission.
