Its function is basically similar to that of physical memory, but it exists as a "backup force" for physical memory. That is to say, it only exists in physical memory. It will only come into play when there is no more use.

When running a program requires a large amount of data and occupies a large amount of memory, the memory will be "filled up" and the temporarily unused data will be placed on the hard disk, and the space occupied by this data is virtual memory.
