Answer:
The code and static data components in the program are allocated memory area that exactly matches their size.
The PCD data and stack share a single large area of memory but grow in opposite directions when memory is allocated to new data.
The PCD data is allocated by starting at the low end of this area while the stack is allocated by starting at the high end of the area. The memory between these two components is free.
In this model the stack and PCD data components do not have individual size restrictions.

Explanation:
The code and static data components in the program are allocated memory area that exactly matches their size.
The PCD data and stack share a single large area of memory but grow in opposite directions when memory is allocated to new data.
The PCD data is allocated by starting at the low end of this area while the stack is allocated by starting at the high end of the area. The memory between these two components is free.
In this model the stack and PCD data components do not have individual size restrictions.
