Sure, WiFi stands for "Wireless Fidelity." The term WiFi was coined as a riff on hi-fi or high fidelity - a term used for high-quality sound reproduction. It's essentially a wireless networking technology that allows smartphones, computers, and other devices to communicate over a wireless signal, typically in the 2.4GHz or 5GHz radio bands. It's an alternative to network cables as a way to connect devices of a local area network. The WiFi Alliance, the organization that owns the WiFi registered trade mark, specifically defines WiFi as "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards." These standards are what allow the interoperability and compatibility between different manufacturers' devices. So when we're talking about WiFi, we're really talking about a type of technology that enables devices to connect wirelessly on a network.
