A JRE (Java Runtime Environment) contains a JVM (Java Virtual Machine). It also contains libraries.

A "java-enabled" browser also invokes a JVM to execute the java code in and points to a JRE to find the Sun provided classes for the application to use.

I think of the JRE as the files which are needed to run a JVM, which is an active process on your computer. You can install a JVM once on your machine, and then you can (if you want) run several simultaneous independent JVMs using those JRE files. [ April 24, 2002: Message edited by: Jim Yingst ]
