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.

Answer:
d. integrity
Explanation:
Data integrity is defined as the condition in which all of the data in the database are consistent with the real-world events and conditions.
Data integrity can be used to describe a state, a process or a function – and is often used as a proxy for “data quality”. Data with “integrity” is said to have a complete or whole structure. Data integrity is imposed within a database when it is designed and is authenticated through the ongoing use of error checking and validation routines. As a simple example, to maintain data integrity numeric columns/cells should not accept alphabetic data.
