Wi-Fi is a wireless networking technology that uses radio waves to connect devices to the internet without physical cables.
What It Stands For?
Not an abbreviation: Officially, Wi-Fi does not stand for "wireless fidelity" or anything else.
The "Hi-Fi" connection: A marketing firm created the term in 1999 because the technical name, IEEE 802.11b, was too hard for consumers to remember. They based the catchy name on a play-off of "hi-fi" (short for high fidelity).
