Virtual Memory

Question 1
Marks : +2 | -2
Pass Ratio : 100%
The binary address issued to data or instructions are called as ______
Physical address
Location
Relocatable address
Logical address
Explanation:
The logical address is the random address generated by the processor.
Question 2

Pass Ratio : 100%
The DMA doesn’t make use of the MMU for bulk data transfers.
True
False
Explanation:
The DMA stands for Direct Memory Access, in which a block of data gets directly transferred from the memory.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
______ translates the logical address into a physical address.
MMU
Translator
Compiler
Linker
Explanation:
The MMU translates the logical address into a physical address by adding an offset.

The physical memory is not as large as the address space spanned by the processor.
True
False
Explanation:
This is one of the main reasons for the usage of virtual memories.
