Assignment Help:

Q. Name two differences between logical and physical addresses?

Answer: A logical address doesn't refer to an actual existing address rather it refers to an abstract address in an abstract address space. Contrast this by a physical address that refers to an actual physical address in memory. A logical address is produce by the CPU and is translated into a physical address by the memory management unit (MMU). Consequently physical addresses are generated by the MMU.
