but, what are the -/+ buffers/cache line? Mem is the phisical memory,
Swap is obvious

linux does not ‘release’ memory until it has to…that is, it keeps in
RAM everything it can until the memory is needed for something
else…the philosophy is that you might need it again and it is a lot
faster to fetch it from memory, than from disk…so, just hold on to it…
so, if you look at the mem line almost ALL is being used for something…
the buffer/cache is where you learn what all that memory is being used
for…
the 1242 is being used by programs now active…the 755 is not really
being used by anything…it is just that stuff still waiting to be used…
if another program needs more memory the cache/buffer used number will
increase and the cache/buffer free number will go down…
