What characterizes an Independent Basic Service Set (IBSS)?

  1. It requires an access point for communication

  2. Devices communicate directly without an access point

  3. It connects multiple access points seamlessly

  4. It is exclusively for long-term communication

The correct answer is: Devices communicate directly without an access point

An Independent Basic Service Set (IBSS) is characterized by devices communicating directly with each other in ad hoc networking scenarios, without the need for an access point. This setup allows devices to connect and exchange data peer-to-peer, enabling spontaneous and temporary networks. In contrast, an access point is not utilized in IBSS; it is instead part of Infrastructure Basic Service Sets (BSS) where devices communicate through access points. Options discussing the connection of multiple access points or long-term communications reflect characteristics of different network setups but do not apply to the ad hoc nature of IBSS, which emphasizes a flexible and dynamic arrangement of devices communicating directly.
