[users] [moderated] YOU MUST GIVE A SUMMARY HERE: sure. what is JRE and how do I know?

[jayd]

I was interested in open office as a friend mentioned it.

But the download is asking me if I have windows bundled with or without JRE.
How do I know?  I don't even know what those initials stand for, not being 
geeky at all.

Please advise.
