The correct answer is Physical address.The Physical address identifies the physical location of required data in memory.In computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitryIt enables the data bus to access a particular storage cell of main memory or a register of memory-mapped I/O devices.Additional InformationIn a computer supporting virtual memory, the term physical address is used mostly to differentiate from a virtual address.In particular, in computers utilizing a memory management unit (MMU) to translate memory addresses, the virtual and physical addresses refer to an address before and after translation performed by the MMU, respectively.
