The OS has to keep track of the physical location where a document is saved on your hard disk; to do this, it maintains the file allocation table (FAT).
RAID 0 can be used to improve performance through concurrent access and/or create large logical disks out of multiple physical disks.
A software RAID program such as mdadm can do this.

Floppy disks are made of materials that degrade with time. Material degradation include cracks and chemical changes such as oxidation. Physical force will break a floppy disk. Heat will melt the disk or hasten oxidation of the material. Spilling something on a disk creates a coating that can alter the physical movement of the disk. Other chemicals can react with the material of the disk and change its physical or chemical characteristics.
The wizard cannot create a virtual disk using the Parity layout with only two physical disks because Parity requires a minimum of three disks to function properly. This is due to the need for distributed data and redundancy; with only two disks, there is insufficient capacity to store the parity information necessary for data recovery in case of a disk failure. Thus, at least three disks are needed to ensure both data integrity and redundancy in a Parity setup.
logical volume manager
LUN = Logical Unit NumberVolume = a physical diskDepending on how the storage is configured a LUN may correspond to: a single physical volume as a single logical unitseveral physical volumes being treated as a single logical unitone partition within a physical volume formatted as several partitions (with each partition as a single logical unit)The concept of a LUN makes it easy for programs to access the disks and makes it easy to perform maintenance on the disks by shuffling the LUNs between physical disks as needed. The programs do not need to be changed or reconfigured when a physical drive is removed, replaced, or upgraded to one of greater capacity (or converted to RAID storage).
A logical representation of one or more physical disks configured to provide redundant and/or large storage space for the system.
A temporary memory is one that loses its contents if energy is cut off. This is normally some variety of RAM.A permanent memory is one that maintains its contents, even without a permanent energy supply. This includes hard disks, CDs, DVDs, and flash drives. Note that the contents of "permanent" memory can still be changed, or damaged.
they are floppy disks
Floppy disks cannot be downloaded; they are physical devices. The data on them, however, can be downloaded, just like any other file.
