Which of the following is a primary benefit of wireless communication?

• A. Supports multiple devices
• B. Mobility
• C. Less invasive
• D. Security

Answer: (B)

Mobility is the standout advantage of wireless communication. Without cables tying a device to a fixed point, you can stay connected while moving around within the network’s coverage area—whether walking through a building, moving between rooms, or roaming in a campus or office. This freedom to move and remain online defines wireless as a primary benefit.

Other options describe valid aspects in some contexts, but they aren’t the defining feature. Wireless can support many devices, but that capability isn’t unique to wireless alone. Security depends on how you implement protections, not on wireless itself being inherently secure. “Less invasive” isn’t a clear, central benefit compared to the ability to roam and stay connected.
