Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. 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 circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory mapped I/O device. In a computer with virtual memory, the term physical address is used mostly to differentiate from a virtual address. In particular, in computers utilizing memory management unit to translate memory addresses, the virtual and physical addresses refer to an address before and after MMU translation respectively.
