What is the difference between wireless network card and wired network card?

1. Connection method:

Wired network cards are connected to the network through physical cables (such as Ethernet cables), while wireless network cards are connected to the network through wireless signals. Wired network cards need to be physically connected to network equipment (such as switches and routers), while wireless network cards are connected to the network through wireless routers or access points.

2. Transmission speed:

Generally speaking, wired network cards have higher transmission speeds. Wired network cards usually support Gigabit Ethernet or higher speeds, while the transmission speed of wireless network cards is affected by the quality of the wireless signal and the distance, and is generally between tens of megabits per second (Mbps) and hundreds of megabits per second (Mbps).

3. Network coverage:

The network coverage of a wired network card is limited by the length of the cable, generally around 100 meters. A wireless network card can connect to the network via wireless signals within a certain range, and the coverage depends on the signal strength and transmission rate of the wireless router or access point.

4. Flexibility and portability:

Wireless network cards have greater flexibility and portability, and can be moved freely within the coverage of the wireless network without being restricted by cable length. However, wired network cards need to be connected via physical cables and are subject to cable length and wiring restrictions when used.

5. Security:

Wired network cards are more difficult to be accessed by unauthorized users than wireless network cards. Wireless signals from wireless network cards can be intercepted or interfered with by others, so security measures (such as encryption) are needed to protect the security of wireless networks.

It should be noted that wireless network cards and wired network cards can exist on the same computer at the same time in actual applications. Users can choose to use wired or wireless connections to access the network as needed.
