Which standard is the most commonly used for wireless networking?

• A. Bluetooth
• B. ZigBee
• C. IEEE 802.3
• D. Institute of Electrical and Electronics Engineers (IEEE) 802.11

Answer: (D)

Wi-Fi, defined by the IEEE 802.11 family, is the most commonly used wireless networking standard. It creates wireless local networks that let devices connect to the internet and to each other through access points. Its broad adoption across devices and vendors, ability to support high data rates, and features like roaming between access points make it the go-to choice for general wireless networking in homes, offices, and public spaces. Bluetooth and ZigBee are specialized for different roles—Bluetooth for short-range peripheral connections, ZigBee for low-power sensor networks—so they don’t serve as the primary standard for general wireless networking. IEEE 802.3 is wired Ethernet, not wireless.
