The loading address can be the same as the memory address, but it's not always the case.
The loading address is the address where the executable code is loaded into memory when a program is executed. The memory address, on the other hand, is the address where the executable code is actually stored in memory.
In some systems, the loading address is different from the memory address because the operating system uses virtual memory. Virtual memory allows a program to use more memory than is physically available by creating a mapping between the process's virtual address space and physical memory. This mapping is controlled by the operating system's memory management system.
In such systems, the loading address is typically different from the memory address because the executable code is loaded into a virtual address space rather than directly into physical memory. The virtual address space can be mapped to physical memory as needed, and the mapping can be changed dynamically as the program runs. This allows the operating system to effectively manage memory usage and prevent programs from interfering with each other's memory.
In summary, the loading address and memory address can be the same or different depending on the system and whether virtual memory is used.
