  • $\begingroup$ You say "page cache" but link to the article on memory paging, and quote from it. That link is describing memory paging, not page cache. That quote begins "memory paging is a memory management scheme...", not "page cache is a memory management scheme...". Yes, memory paging is the same thing as paging, but it's not exactly the same as a page cache. $\endgroup$ Commented Jun 24, 2021 at 4:14
  • $\begingroup$ @D.W. Oh, now it's getting more confusing... Okay, memory paging and paging are the same. paging and page cache not the same. Then, where does page fault occurs, on memory paging or on page cache? where does page replacement occurs, on memory paging or page cache? $\endgroup$ Commented Jun 24, 2021 at 4:40
