RAM is basically a place for programs to store information that it needs to access quickly - as RAM is much faster access than a hard drive, NAND, etc. So the OS uses RAM as a buffer so to speak - between the processor & storage device.

So this is a place for the system to store things temporarily - you can't store things directly on RAM, as it would get cleared out on device shutdown/restart.

So that in my dictionary is a "ramdisk" does Android use a Ramdisk? It could possibly explain why...

Uhm... It uses RAM, perhaps you're thinking of swap? In Windows this is called a page file - basically it slices out a piece of the hard disk to use the same way that RAM is used - but it's supposed to be used very sparingly - in Linux systems it's only used when you run out of RAM. Windows... it's a little more fuzzy.
