Floppy disks were an older technology then diskettes. They were computer storage disks encased in a soft plastic envelope (hence "floppy") that had a bigger diameter than the diskettes which were packaged in a hard plastic cartridge.

The other name for a Floppy Disk is "Diskettes or Floppies" answer by Lloyd Gordon 1-876-471-1662
The commonest size in use is 31/2 inches. Standard capacity is 1.444MB. Earlier models also used 5 1/4 inch diskettes, and even earlier ones used 8 inch diskettes. Those earlier diskettes were "floppy" because they were covered in nothing but a coated cardboard sleeve, and were not rigid thus, hence the popular name "floppy disk."
t he older square-shaped floppy diskettes measured 15 cm on each side. What was the diagonal length of a diskette?
These days (2012) you will not find many floppy disks (although just a couple of years ago we had to order special floppy drives for a server because some software would only be installed if it booted from Drive: A a floppy). There were 8 inch and 5 inch and 31/2 inch floppy disks which were common. The latest (diskettes) were the smallest and were protected by a hard plastic casing. Inside a thin Mylar disk coated with a magnetic surface stored the 1.44 Mb that was the capacity of most diskettes. Hard disks have one or more aluminium or glass disks coated with magnetic surfaces. These hold much more information and now (2012) there are units that can store 3Tb or more.
The only floppy drive system commercially available today is the 3.5" floppy disk drive. Previously there were both 5.25" and 8.00" disks/drives also available for PC's.
