question about acronyms

New to JAVA (is that an acronym as well?)
In my journeys around the www, from URL after URL, and even within various IDE, I see ANT, CVS and one which is possibly just a metaphor: BEAN (maybe they all are). Yet I have not seen what these are or what they mean. Can someone help with that?
Thanks

A URL (Uniform Resource Locator, previously Universal Resource Locator) - pronounced YU-AHR-EHL or, in some quarters, UHRL - is the address of a file (resource) accessible on the Internet.

Java was named after "coffee"
Main Entry: ja�va
Function: noun
Usage: often capitalized
: COFFEE

Davidson said he named the tool "Ant" because it is a little thing that can build big things.

Concurrent Versions System (CVS) is a program that lets a code developer save and retrieve different development versions of source code.

In its JavaBeans application program interface for writing a component, Sun Microsystems calls a component a "Bean" (thus continuing their coffee analogy). A Bean is simply the Sun Microsystems variation on the idea of a component.

Not everything in IT is an acronym.

Of these 5 things, only two are acronyms, and they (URL and CVS) are not Java specific.

General rule of thumb - if it's an acronym, it will be in all capital letters; otherwise, not.

For most of the terms, http://www.whatis.com/ will tell you what it means.

Thanks for the responses and the excellent links (URLs) to most helpful information. This JavaRanch deal is neater than sliced bread.
