[理工] [計組] write back
張凡下冊290頁 題58
(3) In today's computer systems, virtual memory and cache work together as a
hierarchy. When the operating system decides to move a page back to disk,
the contents of that page may have been brought into the cache already.
What should the OS do with the contents that are in the cache?
=====
Force the related blocks to write back if they are dirty or invalid the
related blocks if they are clean.
請問它的題目跟解答是在說什麼@@?
謝謝
