WiFi is wrong. It actually doesn't stand for anything. It just sounded fun and was similar to "hi-fi" that they were like "sure that's marketable, why not".

"According to MIC quoting this interview from 2005 by Boing Boing, Wi-Fi doesn't mean any of these things, and in fact actually means basically nothing at all. Rather, Wi-Fi was a name settled on between a group now known as the Wi-Fi alliance and some brand consultants from Interbrand agency. This kinda feels like when you find out a friend has actually been going by their middle name for years."

It was master and slave because how it worked.
LIN networks still work with master and slave nodes. Most of tose LIN setups are uni directional. No feedback from the slave node.
For drives it was how addressing them worked... iirc, but I'm no expert on this.

While probably true, it's *derived* from Hi-Fi, short for high fidelity, a term that was very important in audiophile spheres back in the day. From about the 50s through the 80s, it was very common to see speakers, record players, tape decks, radios, and all kinds of other audio equipment advertised as hi-fi, and the term stuck enough that when people were coming up with a name for wireless home networking, a variant on it had the right cachet.

It's not a new thing. WiFi was created by the WECA (now the WiFi Alliance) and is the user-friendly name for IEEE 802.11. It was created by a brand-consulting firm and does not stand for anything. Some people at WECA believed that the name needed a literal explanation : that's why it was advertised as "The Standard for Wireless Fidelity". They droped that tag line after a year.
