Final answer:
Virtual memory is a combination of RAM and hard drive space that extends a computer's physical memory and allows it to handle larger amounts of data and run more programs simultaneously. It also stores pages that are currently not in use by physical memory.
Step-by-step explanation:
Virtual memory is a combination of RAM and hard drive space that allows a computer to have more memory than it physically has. It extends the physical memory on the machine, allowing it to handle larger amounts of data and run more programs simultaneously. Virtual memory also stores pages that are currently not in use by physical memory, allowing for efficient use of memory resources.
