etc., that the program ever needs while executing and will be loaded at least once during the entire run.

An application's memory footprint is roughly proportionate to the number and sizes of shared libraries or classes it loads, whereas static libraries, executable programs and static data areas contribute to a fixed (constant) portion. Programs themselves often do not contribute the largest portions to their own memory footprints; rather, structures introduced by the run-time environment
