Which type of wireless communication is based on 802.11 standards?

• A. Wi-Fi
• B. Bluetooth
• C. NFC
• D. Ethernet

Answer: (A)

IEEE 802.11 defines the standards for wireless local area networks, and when devices implement these rules, the wireless network they create is commonly known as Wi‑Fi. This family of standards covers how data is formatted and transmitted, how devices share the wireless medium (using CSMA/CA), and how speed, bands (like 2.4 GHz and 5 GHz, and newer 6 GHz), and security (WPA/WPA3) are handled. Other options use different technologies: Bluetooth has its own short‑range standard for personal area networks, NFC is for very close, near‑field communication, and Ethernet is a wired networking standard (IEEE 802.3). So the wireless communication based on 802.11 standards is Wi‑Fi.
