What characterizes a Wireless Local Area Network (WLAN)?

A Wireless Local Area Network (WLAN) is characterized by its operation using a wireless distribution method, which allows connection of devices without the need for physical cabling. This enables users to connect to the network through various wireless technologies like Wi-Fi. WLANs are particularly valued for their flexibility and convenience, as they facilitate mobility for connected devices such as laptops, smartphones, and tablets within a localized area, often accommodating numerous users simultaneously.

The other options describe characteristics that do not accurately reflect WLANs. Networks using fiber optic cables pertain to wired Local Area Networks (LANs), while geographical limitations do not specifically define WLANs, as they can vary in range. Additionally, referring to them as extremely large networks is misleading, as WLANs are typically limited to smaller areas compared to wider networks like Wide Area Networks (WANs). Thus, the defining attribute of a WLAN's wireless capability is what sets it apart and authenticates answer choice B as the correct one.
