What other names is Virtual memory also known as

Hard disk (HDD), Solid State Drive (SSD), it is a type of "volatile memory"

Explanation:

Virtual memory is an section of "volatile memory" (a type of memory that requires power to be supplied to it to retain the data it is holding) in a computer system's secondary memory storage space such as a hard disk or solid state drive, which acts as if it were a part of the system's RAM or primary memory.

Not sure what the question wants exactly. But virtual memory is stored on the HDD and SSD. I hope that helps.
