WiFi

WiFi is a blanket term for a series of protocols that allow computers to communicate wirelessly with each other, usually with a device in between called an Access Point. There are many different standards of WiFi that define speeds and ranges. But, know that WiFi is the magic that lets you watch cat videos in the bathroom.

And, no, WiFi isn’t short for Wireless Fidelity. WiFi is a trademarked word all by itself.
