Difference between Logical and Physical Address Space?

·         The concept of a logical address space that is bound to a separate physical address space is central to proper memory management.

Logical address – generated by the CPU; also referred to as virtual address.

Physical address – address seen by the memory unit.

·         Logical and physical addresses are the same in compile-time and load-time address-binding schemes; logical (virtual) and physical addresses differ in execution-time address-binding scheme
