What is the difference between stack memory and heap memory in terms of usage volume?

Memory of the stack and heap differ in size and usage:

• Stack — is a fixed-size memory area allocated for each thread. The stack size is usually limited (for example, a few megabytes). Local variables, function parameters, and return addresses are stored in the stack. The stack size is limited and usually smaller than the heap.

• Heap — is a dynamically allocated memory area, which can significantly increase in size depending on the application's needs. Objects and data allocated during runtime (for example, using new in C#) are stored in the heap.

Example: a local variable is stored on the stack, while an object created via new is stored on the heap.
