Virtual memory frees up RAM by transferring data that hasn't recently been used to a storage device, such as a hard disk or solid-state drive (SSD). Virtual memory is useful for multitasking, running large programs, and speeding up the system.
<h3>
What is the role of virtual memory in disk storage space?</h3>
Virtual memory fulfills two functions. First, by using disk, it enables us to increase the utilization of physical memory. Because each virtual address is converted to a physical address, it also enables memory protection.
An operating system may load programs larger than its physical memory thanks to virtual memory, which is its fundamental benefit. The users get the idea that the machine has boundless memory. Additionally, it offers memory security.
Therefore, operating systems move code and data, as necessary, to a portion of the disk that is used as if it were memory, not just disk storage space.

True..they do take great photography..
Option D is correct. If we want multiple users to access data, we will organise that data in Database we can then be accessed whenever needed.
Answer:
Highest
Explanation:
A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.
- Interrupt request 0. – it is a system timer (can not be altered)
- Interrupt request 1 – keyboard controller (can not be changed)
- Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
- Interrupt request 3 – serial port 2 controller
- Interrupt request 4 – serial port 1 controller
- Interrupt request 5 –parallel port 2 and 3
- Interrupt request 6 - floppy disk controller
- Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.
As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .
Depending on what kind of security measures are implemented, D would definitely be a contender. However, B is also something to take into consideration. I would answer D.<span />
