AppleTalk is the Apple's proprietary networking protocol. It can run over
LocalTalk cabling (which is the transport if you will), Ethernet (or
EtherTalk) and TokenRing (or TokenTalk).

So, when you read AppleTalk alone or LocalTalk, that means AppleTalk running
over the proprietary Apple's old networking hardware. It's basically serial,
but a little bit more verbose and smarter. Then, when you read 'EtherTalk',
that means the AppleTalk protocol running over Ethernet cabling. Finally,
you won't probably hear or read about it, but there was a time where you
could have AppleTalk running over TokenRing, or TokenTalk.

funky adj.: Said of something that functions, but in a slightly strange,
klugey way. It does the job and would be difficult to change, so its obvious
non-optimality is left alone. Often used to describe interfaces. The more
bugs something has that nobody has bothered to fix because workarounds are
easier, the funkier it is. TECO and UUCP are funky. The Intel i860's
exception handling is extraordinarily funky. Most standards acquire
funkiness as they age. "The new mailer is installed, but is still somewhat
funky; if it bounces your mail for no reason, try resubmitting it." "This
UART is pretty funky. The data ready line is active-high in interrupt mode
and active-low in DMA mode."
