What technology enables wireless networking?

Wi-Fi is the technology specifically designed for wireless networking, allowing devices to connect to a network without physical cables. It utilizes radio waves to transmit and receive data over the air, enabling users to access the internet, share files, and connect to various devices from various locations within a certain range.

While Bluetooth is also a wireless technology, it is mainly used for short-range communication between devices, such as connecting headphones to a smartphone, rather than for robust networking across multiple devices like Wi-Fi does. Ethernet, on the other hand, refers to wired networking technology that requires physical cables to connect devices. Fiber optics represents a different kind of networking primarily focused on high-speed data transmission over long distances using light signals, but it does not inherently provide wireless capability. Therefore, Wi-Fi is the correct answer as it is the primary technology enabling broad wireless networking.
