Wi-Fi is a wireless networking technology that uses radio waves to provide high-speed Internet access and enable devices like computers, smartphones, tablets, and other electronics to connect to a network without physical cables
. It is based on the IEEE 802.11 family of standards, which define how devices communicate over wireless local area networks (WLANs)
. Contrary to popular belief, Wi-Fi is not an acronym and does not stand for "Wireless Fidelity." The term "Wi-Fi" was created as a brand name by a marketing firm to be a user-friendly name for the IEEE 802.11 standards. The phrase "Wireless Fidelity" was used only briefly as a tagline early on but has no official meaning related to Wi-Fi
. In summary, Wi-Fi refers to the technology that allows wireless communication and internet access via radio waves, and the name itself is a trademarked brand rather than an acronym with a specific meaning.
