ROM Read only mem the way how it works is that it remembers or stores the data even when the Pc is power on/off it’s programmed with the factory form of the BIOS or UEFI

RAM on the other hand of course Read access Memory it’s only helpful doing and after POST process I mean power on self test that when the computer is booting and after booting so when the computer is powered off RAM is dormant it doesn’t help

Virtual memory is the memory of the management capacity of an OS operating system that uses part of hardware and software to allow a computer to compensate for physical memory shortage by temporary transferring data from RAM to disc storage and this means virtual memory is used inform of paging files

Summary
When the pc is off ROM is helpful

When off or in Hubernation RAM doesn’t help

Virtual mem extends mem in the absence of the physical memory
