"right" is really a strong word in this case :)
Look at my comments further bellow.

Try running "free -m" from the command line. The output will be
something like this:
total used free shared buffers cached
Mem: 249 245 4 0 3 63
-/+ buffers/cache: 178 71
Swap: 511 467 44
What it means is that in "total" I've 249Mb of "Mem" (physical memory
that is) and 511Mb of swap space.
Of these, 245Mb of my memory are being used, and 4 are free. Of these
245 used, 63 are for cache, that is: stuff that will make the system
What this means is taht 178Mb (the number after -/+ buffers/cache) is
ACTUALLY being used by programs, the rest of the memory (71Mb) is
considered free, if any application ever need it.
In my case, a memory upgrade would be good, since, under a normal
load, my swap is 467Mb.
If you need more help with these, please ask.
