The contents of memory may have come from a file on disk, or they may have been created in RAM. If the latter, they are called anonymous pages. Most of the time this is associated with the stack and heap of a running program.
When memory is tight and pages are released, a named page can simply be dropped. In the future it can be reread from disk. Anonymous pages don't exist elsewhere so they would have to be written to backing store (swap) before the page could be released.
