What types of memory for data storage exist for a single process in an operating system?

In a process, the operating system allocates several types of memory for storing data:

• Stack — used for storing local variables and function calls. Memory is allocated and freed automatically when entering and exiting functions.
• Heap — a region of dynamic memory where objects and data allocated during program execution are stored (for example, using new in C#). Memory management here is more flexible but requires garbage collector control.
• Data Segment — contains static and global variables that exist throughout the lifetime of the process.
• Text Segment — the memory area where the executable code of the program is stored.

In the context of C#, the main focus is on the stack and heap, where the stack stores local variables and method parameters, and the heap contains objects managed by the garbage collector.
