What is a Wireless Local Area Network (WLAN)?

1. A network where all devices are connected through cables

2. A local area network with wireless connections

3. A network limited to mobile devices only

4. A type of personal area network

The correct answer is: A local area network with wireless connections

A Wireless Local Area Network (WLAN) is defined as a local area network that utilizes wireless connections to allow devices to communicate and connect without the need for physical cables. This type of network is typically used to provide internet access and to support communication among devices like computers, smartphones, tablets, and printers within a limited geographic area, such as a home, office, or school. The essence of a WLAN lies in its ability to provide mobility and flexibility, enabling users to move around freely while staying connected to the network. This is achieved through the use of various wireless technologies, such as Wi-Fi, which operate over radio waves. By contrast, networks where all devices are connected through cables do not fall under the WLAN category; they would typically be classified as wired local area networks (LANs). A WLAN is not limited to mobile devices alone, as it can accommodate a variety of devices, including desktops and printers that may not be portable. Additionally, a wireless local area network should not be confused with personal area networks (PANs), which specifically refer to networks designed for personal devices over short distances, such as connecting a smartphone to a headset. Therefore, the definition provided in the correct choice accurately captures the primary characteristic of WLAN technology.
