Which technology provides wireless networking capability?

Wi-Fi is the technology that provides wireless networking capability, allowing devices to connect to a network without physical cables. It operates through radio waves, enabling wireless communication between devices such as computers, laptops, smartphones, and routers. This wireless communication is facilitated through various Wi-Fi standards (like 802.11a, b, g, n, ac, ax), which define the methods and frequency bands used for transmission.

Understanding the function of Wi-Fi is crucial in the context of networking because it relies on the IEEE 802.11 protocols to establish connections in homes, offices, and public spaces. This capability is particularly important as it allows for mobility and flexibility, enabling users to access the network from various locations without being tethered to a wired connection.

Other technologies mentioned, such as satellite and fiber optics, serve different functions in networking. Satellite technology is used for communication over long distances and can provide internet access, but it does not inherently provide a local wireless network within a space. Fiber optics, while a very high-speed data transmission medium using light, require physical cables to connect devices and do not offer wireless capabilities. Ethernet, similar to fiber optics, involves wired connections through cables and switches. Thus, among the options, Wi-Fi uniquely stands out as
