Shouldn't Total Physical Memory be the sum of Available and System
Cache? I have 1GB of RAM in my machine.

Without even looking (since I have read it is possible to
put "code" inside pictures, and I do not risk running any
unknown code, ever) I will say that if your motherboard
has an integrated video adapter, your memory count will be
reduced by the amount of "shared" video memory

Total physical memory is your RAM - only. System cache is RAM that is used
as such and is subtracted from the "total physical".

I think the concern you have is about pictures you download to your
computer. My picture is just a jpg on a web site just like the other
millions and millions out there.

Here's the ascii version of my 'picture'

Physical Memory (K)

Total................ 1047276
Available............ 501656
System Cache......... 701512

As you can see the Total is less than the sum of the two parts. My
onboard video memory is 256MB which if you add to the total is close to
the sum of the two values.
 
From Task Manager HELP:

Performance measures
Totals, in kilobytes, for physical, kernel, and commit memory.

physical
The physical memory installed on your computer.

kernel
Memory used by the operating system. Non-paged kernel memory is available
only to the operating system. Paged memory can be used by other programs
when necessary.

commit
Memory allocated to programs and the system. Because of the virtual memory,
the value listed under Commit Peak memory may exceed the maximum physical
memory.

Commit Charge (K)
Memory allocated to programs and the operating system. Because of memory
copied to the paging file, called virtual memory, the value listed under
Peak may exceed the maximum physical memory. The value for Total is the same
as that depicted in the Page File Usage History graph.

Physical Memory (K)
The total physical memory, also called RAM, installed on your computer.
Available represents the amount of free memory that is available for use.
The System Cache shows the current physical memory used to map pages of open
files.

Kernel Memory (K)
Memory used by the operating system kernel and device drivers. Paged is
memory that can be copied to the paging file, thereby freeing the physical
memory. The physical memory can then be used by the operating system.
Nonpaged is memory that remains resident in physical memory and will not be
copied out to the paging file.

Yeah....but the picture DOES download to your computer - every time, every
web site you view. The "web cache" stores all the pages you ever visit....
