Wow, those are awful. I tend to take a porn approach for things like this in that you know it when you see it. If it's unambiguous I think it's fine, in the case of internet connection, but I can see all of those as being confusing (except maybe "giga" in context like that, but regardless that one is just too much and I hate it). Obviously, what's "obvious" is completely dependent on context, background, and environment, so it's a pretty poor place to draw a line, but I'm still sticking to it and relying on humans to make appropriate judgment. Edit: Actually, I've rethought the "giga" one and don't really think it's too bad if context is clear. In the states people say "gigs" similarly to mean both data transfer and storage in different contexts and it's usually clear. "Giga" only sounds strange to me because I'm not used to that word, but it's effectively the same, just a shortening of a phrase. I suppose "USB" is just a shortening as well, but without extreme context it's just too unclear because it refers to the bus, or more commonly the connector. If they're holding the drive in their hand and gesturing that's probably fine, but otherwise "drive" or "storage" is needed. Wi-fi is just blatantly wrong though.
