Answer 1

THERE IS A HUGE DIFFERENCE BETWEEN PHYSICAL AND LOGICAL MEMORY

LIKE WHEN U DO SOME HARD OR PHYSICAL WORK OR EXERCISE THEN ITS GIVE U PHYSICAL FITNESS AND LOGICAL MEMORY IS THAT WHEN U GIVE PROOF LOGICALLY LIKE 2+2=4

Answer 2

Answer: Address generated by CPU is Logical address whereas address loaded into the memory address register of the memory is Physical address.

Compile time address binding method generates logical addresses.

Load time address binding method generates physical addresses.

Explanation:Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a program’s perspective.

Physical Address identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address. The user program generates the logical address and thinks that the program is running in this logical address but the program needs physical memory for its execution, therefore, the logical address must be mapped to the physical address by MMU before they are used.
