Yes, I think so.  I think that it is difficult to say that a system
has no 'swap area', because a 'swap area' could be a file.

How can you be sure that none of the files on a system are
a 'swap file' ?

I think that you can say that a system has no 'swap' or 'virtual memory'
if there are no swap areas enabled.

I suggest that the output of 'free' will indicate your swap. If 'free' indicates that you have no swap, then you have no swap. If 'free' indicates that you have swap, then you have swap.

is this correct? because i feel even if this swap area
is not there then also virtual memory concept exists?

A system can have a swap partition and not use it.
A system can have a swap file          and not use it.
Swap can be enabled and disabled on a running kernel.
So, at any given instance, a running system can have
or have not 'virtual memory'.

thanks

(1) A swap file or swap partition can be used as virtual memory. (2) I am not sure. Why one would wish to use
'swap

area' interchangeably with 'virtual memory'. :-| Chuck
