What is WiFi?

• A. A wireless technology that uses radio waves to transmit data
• B. A wired Ethernet standard
• C. A protocol for secure file transfer
• D. A social media platform

Answer: (A)

WiFi is a wireless technology that uses radio waves to transmit data. It lets devices like smartphones, laptops, and tablets connect to a local network or the Internet without physical cables, by communicating with a wireless router or access point. It follows IEEE 802.11 standards and typically uses the 2.4 GHz and 5 GHz frequency bands (with newer 6 GHz support in recent versions), allowing many devices to share the network at once. It’s not a wired Ethernet standard, not a protocol for secure file transfer, and not a social media platform.
