What does wireless fidelity (Wi-Fi) refer to?

Wireless fidelity, commonly known as Wi-Fi, refers to a method that facilitates the wireless connection of portable devices to a local area network (LAN). It allows devices such as smartphones, laptops, and tablets to access the internet or communicate with other devices within the same network without the need for physical wiring. This technology is based on standards established by the IEEE 802.11 protocol suite, which defines how devices can communicate over radio waves, ensuring compatibility and interoperability across different device manufacturers.

Understanding the context of this option makes it clear that Wi-Fi significantly enhances user mobility and convenience, making it integral to modern networking. This capability transforms not only personal computing but also enterprise settings by allowing flexible work environments and the integration of various wireless devices.
