JRE: Java Runtime Environment.
JVM: Java Virutal Machine

The JVM is a part of the JRE.

the JRE contains everything you need to run Java programs.
The JVM basically is the virtual computer Java Programs are compiled for (google "Java Byte Code").

Microsoft also offers it's own Version of the JVM (Microsoft virtual Machine), which is on a tecnical level like 8 years ago. They don't support it anymore.

What do you need to know?

Download it (Java Runtime Environment (JRE) 5.0 Update 7) here and see for yourself

Special "plugins" like Quicktime for Java or Java3D are avaiable on other sites.
