Which term describes a wireless networking technology for local area networks?

• A. DNS
• B. Cloud
• C. Ethernet Switch
• D. Wi-Fi

Answer: (D)

Wi‑Fi is the wireless networking technology used for local area networks. It uses radio waves to connect devices like laptops, phones, and tablets to a network within a limited area such as a home or office, without requiring cables. An access point or router serves as the network hub for these wireless connections. This differs from wired options, like an Ethernet switch, which requires cables to connect devices. The other terms refer to different concepts: DNS translates web addresses to IP addresses, and Cloud describes remote services and storage hosted on the internet. So for a wireless local-area network, Wi‑Fi is the right term.
