Solution

The correct answer is Statement I is correct but Statement II is incorrect

Key Points

• Statement I is correct - Address translation is performed for every logical address used during the execution of a program
  • Virtual memory systems use a process known as address translation to convert a program's logical addresses into physical addresses used to access the actual memory hardware. This translation is done for each logical address that is generated during the execution of a program.
• Statement II is incorrect - A program can execute only when all of its components are loaded in the memory
  • One of the significant advantages of virtual memory is that it allows programs to be executed even when all of its components are not loaded into memory. This is done by loading parts of the program that are currently needed, or pages, into physical memory while the rest of the program remains on the disk. This technique is also known as demand paging.
