:: FLOOPY DISK ::

To complete the task given from MR.SYZRY AFFENDY :) , I prefer to choose FLOOPY DISK in storage devices topic. It is type of output storage .

Electronic commerce and electronic business, and regulations such as Sarbanes-Oxley,have made storage a strategic technology. The amount of data that companies now need to store is doubling every 12 to 18 months. The principal storage technologies are magnetic disks, optical disc, magnetic tape, and storage networks.

Floopy disk is a SECONDARY storage which is one of the example is floopy disk in magnetic disk.

 The rest are internal hard disk and external hard disk.

  Nowadays , although people is rarely used the floopy disk , but it is very necessary and very beneficial to store a data in computer at one time. A flexible plastic disk coated with magnetic material and covered by a protective jacket, used primarily by computers to store data magnetically.

 Also called diskette.

A soft magnetic disk. It is called floppy because it flops if you wave it . 

Unlike most hard disks, floppy disks (often called floppies or diskettes) are portable, because you can remove them from a disk drive. 

Disk drives for floppy disks are called floppy drives. Floppy disks are slower to access than hard disks and have less storage capacity, but they are much less expensive. 

And most importantly, they are portable.

Floppies come in THREE basic sizes:

8-inch: The first floppy disk design, invented by IBM in the late 1960s and used in the early 1970s as first a read-only format and then as a read-write format. The typical desktop/laptop computer does not use the 8-inch floppy disk. 

5-inch: The common size for PCs made before 1987 and the predecessor to the 8-inch floppy disk. This type of floppy is generally capable of storing between 100K and 1.2MB (megabytes) of data. The most common sizes are 360K and 1.2MB.

3-inch: Floppy is something of a misnomer for these disks, as they are encased in a rigid envelope. Despite their small size, microfloppies have a larger storage capacity than their cousins -- from 400K to 1.4MB of data. The most common sizes for PCs are 720K (double-density) and 1.44MB (high-density). Macintoshes supportdisks of 400K, 800K, and 1.2MB.
