What is WLAN commonly referred to?

WLAN stands for Wireless Local Area Network, and it is indeed commonly referred to as a local area network that utilizes wireless technologies to connect devices within a limited geographical area, such as a home, office, or campus. This type of network allows for the connection of devices like laptops, smartphones, and tablets without the need for physical cabling, enabling greater flexibility and mobility for users.

The other choices do not accurately define WLAN: wired networking technology refers to traditional networks that rely on physical cables, which is not relevant to WLAN. An international networking standard is too broad and does not specifically match the definition of WLAN, which is a specific type of network. Lastly, while Bluetooth is a form of wireless technology, it operates on a different principle and is used for short-range communication between devices, rather than for creating a local area network like WLAN does.
