Answers:

->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



logical address is used in virtual memory while physical address is used in main memory.
