Dear managers,

Thanks to:
Owens, Vincent J
Casper Dik

The word pages and clicks can be used interchangeable and its unit of measure is `pagesize` bytes.
The total of all the SZ-fields does not necessarily reflect the amount of RAM in your system
because not all processes are resident in memory but can be (partially) swapped out and the SZ-field also
includes memeory occupied by shared libraries.

My next question:

Is there a way to know the amount of memory a process occupies in physical RAM ?
