Acronym for Unix to Unix Copy Protocol
UUCP was a text-only method of passing files (usually email and UseNet groups) between machines. It was generally used for links that were not permanently connected so that information could be stored and forwarded.
Used to get Internet onto BBSes in the early days; dropped when no-one cared.
Replaced in the most part by permanent links that stayed up.
