Virtual memory is the reason why applications can think they have 4GB of memory while your physical machine might actually have only 32MB. You don't need to have swap in order to have virtual memory, although its very advantageous to have swap with VM. Virtual memory maps the viurtual pages (from 0 to 4GB) to actually physical memory pages (from 0 to however much RAM you have). Swapping is the process of using the disk to store physical memory pages when they are not in use, and then restoring them when an application accesses them. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
