platter is very stiff it is a hard drive, if it is highly flexible
it is a floppy disk, if it is a floppy disk in a hard housing
with a shutter it is commonly called a diskette.
Disk Drive
The hardware which spins the disk and has the heads
and control circuitry for reading and writing the data
on the disk.
Diskette
A floppy disk in a hard housing with a shutter.
DMA
Direct Memory Access. Special circuitry for memory
to memory transfers of data which do not require
CPU action.
