Final answer:
The question refers to the term for the address loaded into the memory address register, which is called the physical address. This is the actual memory location in hardware where data or instructions are stored, not to be confused with the logical address used by software programs.
Step-by-step explanation:
The address loaded into the memory address register of the memory is referred to as the physical address. The term physical address refers to the actual location in computer memory hardware where data or instructions reside. This contrasts with a logical address, which is an address that is used by a program to access stored information, but must be translated into a physical address by the memory management unit (MMU) before the actual memory access can occur.
