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?
