Explanation & Hint:
The two true statements about Windows virtual memory are:
- Virtual memory combines the RAM memory with the hard disk space to compensate for the lack of RAM.
This statement is accurate. Virtual memory is a memory management technique used by operating systems, including Windows, to provide the illusion of having more physical memory (RAM) than is actually available. It does this by using a combination of RAM and space on the hard disk as a temporary storage area for data that cannot fit in RAM.
- A virtual address does not represent the actual physical location of an object in memory. Instead, the system maintains a page table for each process, which is an internal data structure that is used to translate virtual addresses into their corresponding physical addresses.
This statement is also true. In a virtual memory system, applications work with virtual addresses, which do not directly correspond to the physical location of data in RAM. The system uses a page table to map virtual addresses to physical addresses, allowing for efficient management of memory resources and facilitating the illusion of a contiguous address space for each process.
The other two statements are not accurate:
- Adding a larger disk drive to a system does not automatically increase its virtual memory allocation. Virtual memory is typically managed by the operating system, and the size of the virtual memory space is determined by system settings and available disk space.
- Adding more RAM to a system does not automatically increase the need for more virtual memory. In fact, adding more RAM can reduce the reliance on virtual memory because there is more physical memory available for applications and processes.
