Is a secondary storage for memory that is swapped or paged out. It is also used for saving the kernel corefile when the system panics. Some systems compress their corefile to swap and others don't (BSD doesn't), this is why it's a good idea to have 1.5 to 2 times as much swap as physical memory in a machine (as a rule of thumb), so that you can get a good corefile.
