Many programs automatically look for and use available RAM (system RAM) to give them more room to operate (e.g. desktop space). Many programs load themselves into the available RAM at startup. This greatly increases their performance speed because it reduces or eliminates the need to access the relatively slow mechanical floppy drives.
You have probably already experienced the thrill of loading your favorite (or most used) programs into a volatile RAM Disk and then seeing those programs run faster than they ever could from a floppy disk. You could access these programs from RAM all day. But flipping the power switch or a power outage is like a lobotomy to a RAM Disk.
Now you can know the joy of turning on your computer and having those programs that you previously loaded into RAM appear on your screen instantly. No more setting up a RAM Disk and loading the program every time you turn on your computer.
