Which wireless standard is denoted by Wi-Fi?

• A. 802.11
• B. 802.3
• C. 802.15
• D. 802.16

Answer: (A)

The standard denoted by Wi-Fi is 802.11. This standard specifically defines the technologies for wireless local area networks (WLANs). It encompasses several amendments that enhance performance, range, and speed of wireless networking. Wi-Fi technology, operating within this framework, has become the backbone of wireless connectivity in homes, offices, and public spaces due to its ability to provide seamless internet access without the need for physical cables. In contrast, the other standards mentioned serve different purposes: 802.3 pertains to Ethernet networking, which is used primarily for wired local area networks; 802.15 focuses on wireless personal area networks (WPANs), often used in short-range communications like Bluetooth; and 802.16 is related to broadband wireless access, generally referred to as WiMAX, which caters to wide-area networks. Each of these variations is designed to fulfill specific networking needs that differ from what Wi-Fi (802.11) addresses.
