Can you describe the fundamental principle underlying the memory model in programming systems?

The fundamental principle of the memory model in programming systems is the division of memory into regions with different purposes and lifetimes of data. For example, in Java, memory is divided into the stack and the heap:

• Stack stores local variables and function calls, operates on a LIFO basis, and is quickly allocated and freed.
• Heap is used for dynamic object allocation and is managed by the garbage collector.

This division allows for efficient memory management, ensuring safety and performance of the program.
