Question: In some Windows operating systems, the paging file is a hidden file on the computer's hard disk and its virtual memory is the combination of the paging file and the system's physical memory. (This is called pagefile.sys and the default size is equal to 1.5 times the system's total RAM.) Describe in your own words how you can display the size of the pagefule.sys, and how a virtual memory size that's too small might affect system performance.
