localhost, local, . question

Do you know the difference between
(a)localhos
(b) local
(c)
I've heard that they use different network layers but can't get any info on it
TIA
FThis is my understanding:
Localhost is resolved by the IP stack.
(local) is resolved by the netlib, which means that it can use any network protocol (NetBEUI, IP, IPX etc)
I recall someone mentioning that . will only be resolved through Named Pipes. Not sure about this, though.

(127.0.0.1). Try "ping localhost" from the command prompt.
(local) and . use a protocol called shared memory and does not use any
network protocols.
