logical and physical addresses

Name two differences between logical and physical addresses.
Answer: A logical address does not refer to an actual existing address;
rather, it refers to an abstract address in an abstract address space. Contrast
thiswith a physical address that refers to an actual physical address
in memory. A logical address is generated by the CPU and is translated
into a physical address by the memory management unit(MMU). Therefore,
physical addresses are generated by the MMU.
