12 GC automatically recycles memory that will never be used again.
13 GC used to recycle memory allocated as result of application work (objects, compiled code etc).
31 - Internal memory space for non-compiler part of runtime (including GC internals)
47 # Key Features of the Memory Management System
71 - Memory management flexible enough to work with multiple languages.
