What type of Network Interface Card (NIC) uses the 802.11b protocol?

The 802.11b protocol is specifically designed for wireless networking, making a wireless network (Wi-Fi) card the appropriate type of Network Interface Card (NIC) that utilizes this standard. This protocol enables wireless devices to communicate over radio waves, allowing for the creation of local area networks without the need for wiring.

Unlike wired Ethernet cards, which connect devices through physical cables (like twisted pair or coaxial cables), a Wi-Fi card relies on wireless signals. Bluetooth cards serve a different purpose, primarily enabling short-range communication between devices, not the broader network connectivity that comes with the 802.11b standard. Fiber optic cards, on the other hand, are used for high-speed, high-bandwidth connections over fiber optic cables, which is unrelated to the function of the 802.11b protocol.

In summary, the wireless network (Wi-Fi) card is the type of NIC associated with the 802.11b protocol because it facilitates wireless communications in local area networks.
