Nope. Swap is not needed. It can help, but I've run systems with 512MB-1GB of RAM with no swap, with no issues. It wasn't long ago that most systems had 256MB of swap+RAM total. Having actual RAM is better than swap. Swap is there to make up for not having enough physical RAM. RAM is cheap nowadays, so the need for swap is greatly reduced.
Not quite. No matter how much RAM you have, swap is still a good idea (though of course not technically required). Some times it makes more sense for Linux to swap out a program so it has more RAM to cache files in. If you have no swap, it can't do that.
Ok, in the real world then - what is the default mode in a system having the whole 8 Gigs of memory on board? Is the "swap" then truly no longer a needful concept, or does it become a virtual swap to a soft set memory area?
