In Windows 7 and Windows 2008 R2, there is a new Resource Monitor that is very useful and powerful to monitor the system.
In the Memory section, I see a section called Modified (orange)
The official description is: Memory whose contents must be written to disk before it can be used for another purpose.
But I am still confused. What kinds of memory is Modified? In which case can we say that this number of memory is Modified? Can anyone give me a specific example?
Is the following guess correct?
When a program want to write something into disk, it actually write the content to an IO buffer, which is in the memory. After OS flush this area of memory into disk, the memory is modified or standby?
