MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The logical address is generated by the CPU while the program is running whereas the physical address is computed by the Memory Management Unit (MMU).

Detailed explanation-2: -Explanation: Memory Management Unit, is used to add the offset to the logical address generated by the CPU to get the physical address.

Detailed explanation-3: -Since a logical address does not physically exists it is also known as a virtual address. This address is used as a reference by the CPU to access the actual physical memory location. There is a hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address.

Detailed explanation-4: -The CPU generates the logical address while the program is running, whereas the physical address is computed by the Memory Management Unit (MMU).

Detailed explanation-5: -MMU(Memory Management Unit) : The run time mapping between Virtual address and Physical Address is done by a hardware device known as MMU. In memory management, the Operating System will handle the processes and move the processes between disk and memory for execution . It keeps track of available and used memory.
