Wireless Fidelity. Local wireless technology that allows devices to exchange data.
Wi-Fi, often referred to as WiFi, wifi, wi-fi or wi-fi, is often thought to be short for Wireless Fidelity but there is no such thing. The term was created by a marketing firm because the wireless industry was looking for a user-friendly name to refer to some not-so-user-friendly technology known as IEEE 802.11.
