Final answer:
A WLAN configured to work in an ad hoc fashion is known as an Ad-hoc WLAN. These allow direct device connections without an access point and are used for temporary networks or where traditional infrastructure isn't feasible.
Step-by-step explanation:
A wireless LAN (WLAN) configured to work in an ad hoc fashion, meaning without the need for an access point, is known as a c) Ad-hoc WLAN. This setup allows devices to connect directly to each other, rather than through a central device such as a router or access point. Ad-hoc networks are often used in situations where a temporary network is needed, or in places where infrastructure for a traditional network is not available or practical.
A wireless LAN (WLAN) configured to work in an ad hoc fashion (that is, without requiring the use of an access point) is known as an ad-hoc WLAN. In an ad-hoc WLAN, devices connect directly to each other without the need for a central access point. This type of WLAN is commonly used for peer-to-peer communication between devices, such as sharing files between laptops or smartphones.
