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

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

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.
