What is WLAN?

WLAN (Wireless Local Area Network) is a wireless computer network that links two or more devices using wireless communication within a limited area such as a home, school, computer laboratory, or office building. WLANs allow users to move around within the local coverage area while maintaining a network connection. It is commonly used for internet access, file sharing, and connecting various devices like laptops, smartphones, and printers to a network without physical cables.
