Detailed explanation-1: -13. is generally used to increase the apparent size of physical memory. Explanation: Virtual memory is like an extension to the existing memory.
Detailed explanation-2: -Virtual memory is usually much larger than physical memory, making it possible to run programs for which the total code plus data size is greater than the amount of RAM available. This is known as “demand paged virtual memory".
Detailed explanation-3: -Virtual memory is a common technique used in a computer’s operating system (OS). Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage.
Detailed explanation-4: -Virtual memory provides virtual address mapping between applications and hardware memory. Virtual memory provides many functions, including multitasking (multiple tasks executing at once on one CPU), allowing multiple processes to access the same shared library in memory, swapping, and others.
