RAM:- little less fast(than cache) but still MIGHTY fast, purpose is to act as buffer between "storage memory" and Cache memory.
Hence purpose of ram is to quickly fetch data both ways IN n OUT of processor which cannot be substituted by virtual memory. Anyways virtual memory will be your SD card which is not even 1/100th the speed at which RAM operates.
why do i think you didn't answer the question?
i know how a computer works in general, so explaining cache, ram and hard disks doesn't really solve anything.
so does my processor use all of the allocated RAM? correct me if i'm wrong, but i don't think so because afaik
android only kills apps if you back out, not if you exit by pressing the menu button. so i wouldn't really care if that were stored on a swap partition.
just so you know, i don't think swap partitions make sense (because those 280mb of RAM seem sufficient for me, so i just wouldn't bother), but either say you don't know the answer or give a good one (not lol omfg so stoopid srsly doode never bin to school, ay?), there are already enough fake facts flying around in the interwebs and everywhere else.
here you get a proper discussion about it Why Android Swap Doesn’t Make Sense Zero Credibility
