What's the difference between Managed/Byte Code and Unmanaged/Native Code?

Question

Sometimes it's difficult to describe some of the things that "us programmers" may think are simple to non-programmers and management types.

So...

How would you describe the difference between Managed Code (or Java Byte Code) and Unmanaged/Native Code to a Non-Programmer?

Answer 1

Managed Code == "Mansion House with an entire staff or Butlers, Maids, Cooks & Gardeners to keep the place nice"

Unmanaged Code == "Where I used to live in University"
