There is no official full form for Wi-Fi. While many people believe it stands for Wireless Fidelity, this is simply a memorable phrase coined by the Wi-Fi Alliance, an industry group that promotes and certifies Wi-Fi products.
The term Wi-Fi itself is a shortened version of "Wireless Fidelity", chosen to evoke a sense of high-fidelity sound systems like "Hi-Fi". This was a clever marketing strategy to suggest the high quality and reliability of wireless internet connections.
Although "Wireless Fidelity" is widely used as the full form of Wi-Fi, it's important to note that it's not an official abbreviation or acronym. Wi-Fi is simply a brand name for the technology that uses the IEEE 802.11 family of standards to provide wireless internet access.
