What is the role of virtual memory in resource management of the operating system?

Virtual memory is a mechanism of the operating system that allows programs to use more memory than is physically available in the system by utilizing disk space (swap file or swap partition).

The role of virtual memory in resource management of the OS:

• Abstracts physical memory, providing processes with their own address space.
• Enables efficient use of RAM by loading only the pages of data needed at the moment.
• Ensures memory protection by isolating processes from each other.
• Simplifies memory management by allowing the OS to move data between RAM and disk without application intervention.

Thus, virtual memory helps the OS manage limited memory resources, ensuring stability and security of application operation.
