Explain Total Physical Memory vs.Available Physical Memory
I would like an explanation of the difference between Actual Memory & Virtual Memory. I am concerned because my 2month old Dell Dimension 2400 running Windows XP Home, which I had 256 MB installed shows I have 256 MB Total Physical Memory and 54 MB Available Physical Memory.The Available Memory varies between 14.00 to 98.00 MB. I found this under "System Information" I do not know if this means I do not have enough memory installed in my computer or not. The program also shows me that I have Total Virtual Memory of 879.45 MB & Available Virtual Memory 417.84 MB. I would like to be able to install Windows Service Pack 2, but it is a very large program and I doubt if I have enough memory for it. Please help.

256MB of RAM is sufficient for Windows XP although 512MB is better. To get a better feel for how close you are to running out of memory open Task Manager (Ctrl-Alt-Delete) and look at the Commit/Charge: figure at the lower right corner. The numerator of that figure shows the amount of memory in use, the denominator shows the total amount available (both physical and virtual). When the numerator exceeds the amount of physical memory installed, the computer's performance will decrease as programs use slower disk-based virtual memory rather than RAM but I suspect this is not the case with your system.
As far as installing SP2, the amount of RAM you have does not present a problem. SP2 will not all be loaded into memory at one time.
