Free – This one is quite simple. This memory has nothing at all in it. It’s not being used and it contains nothing but 0s.
Available – This numbers includes all physical memory which is immediately available for use by applications. It wholly includes the Free number, but also includes most of the Cached number. Specifically, it includes pages on what is called the “standby list.” These are pages holding cached data which can be discarded, allowing the page to be zeroed and given to an application to use.
Cached – Here things get a little more confusing. This number does not include the Free portion of memory. And yet in the screenshot above you can see that it is larger than the Available area of memory. That’s because Cached includes cache pages on both the “standby list” and what is called the “modified list.” Cache pages on the modified list have been altered in memory. No process has specifically asked for this data to be in memory, it is merely there as a consequence of caching. Therefore it can be written to disk at any time (not to the page file, but to its original file location) and reused. However, since this involves I/O, it is not considered to be “Available” memory.
Total – This is the total amount of physical memory available to Windows.
The real number that matters is the Total amount that is read by the system, not the amount of RAM avaliable to a process.
