I've read the following 2 articles explaining the difference between virtual memory
and physical memory
. One thing that I found confusing is that the term virtual memory
seems to mean different things in these 2 articles.
What Is the Difference Between Virtual Memory & Physical Memory? says Virtual memory is used when the RAM is filled.
While Wikipedia says virtual memory is used to tell programs where the physical memory is.
Is one of the articles wrong? Or does virtual memory
have different meaning in different context?
