What do you call a small network that forms spontaneously to connect devices without a dedicated access point?

• A. AdHoc
• B. Administrator
• C. ActiveX
• D. Adware

Answer: (A)

An ad hoc network is a temporary, self-organizing wireless network where devices connect directly to each other without a central access point. In this setup, each device acts as a peer, and communication happens without a dedicated router or infrastructure, making it ideal for quick, local sharing or collaboration between nearby devices. Because there’s no centralized controller, the network is generally easier to set up on the fly, but it’s usually smaller in scale, has limited range, and security relies on simpler, device-centric protections rather than enterprise-style authentication. In Wi‑Fi terms, this is often called ad hoc mode or IBSS, contrasted with infrastructure mode that uses an access point.

The other terms don’t fit because they aren’t network topologies: an administrator is a person who manages systems, ActiveX is a software component technology, and adware is software that displays ads.
