Welcome to the JavaRanch.

Like Joachim already said please UseRealWords. Using these abbreviations only cause confusion since we have a lot of people that don't speak English natively (including me).

You don't really need to know how Java byte code works to be able to program in Java. Most programmers don't and don't really care.

In summary, the answer to the question is no - there is no way to explain Java bytecode (and the JVM) in simple terms, because it's a rather complex mechanism.

If you're curious at what the bytecode for a program looks like, then you can use the javap tool to show the bytecode.

But this isn't a "beginning" subject, so I shall move this discussion.
I agree. Here's the link:
