Suppose a memory manager has chosen a modified page for replacement. This page must be sent to secondary storage before the new page may be placed in its page frame. Therefore, the memory manager requests an I/O operation to write this page to secondary storage.An entry is made in a list of I/O requests waiting to be serviced. Thus the page will remain in main memory for some time before the requested I/O operation is performed.
