As the name implies: BACKUP Data to protect against Data Loss. Data Loss can be in several forms and caused by several things:
1) Virus and their ilk
2) Hardware failure (it's not uncommon for Hard Drives to fail)
3) Accidental/Intentional Data Destruction (An accidental click of the 'Delete' button...inexperienced user on a common computer (children or relatives), Disgruntled family member/employee, Software/hardware caused system crash.
4) Theft/Vandalism
5) Fire/Flood/Act of God
6) This is a long-shot, but let's just mention a loss of the Computer Administrator which causes inaccessibility to computer data (Master Computer has complicated PW and Person in charge of that PW/Data dies). Hey, unlikely, but possible.
Methods of Backup:
1) OS-based Backup Software (typically backs-up to the Primary Hard Drive)
2) Hardware-Based Backup
a) RAID or similar (prevents from single or multiple disk failures
b) Network Backup device (saves data to a location (either HD or otherwise) which is not located on the same computer as the data itself)
3) Burn-to-Disc method (perform regular scheduled backups to a CD or DVD and then store this disc(s) in a safe location (fireproof safe if available)).
4) Online Data Backup (Paid Service such as Cryptonite, Cloud-based storage, ISP provided storage, web-based FTP or similar, etc). This is Storage Space either Free or otherwise which is located on Servers which can be accessed via the Web/internet/VPN/etc...they are NOT located at the same location as the Data/Computer itself.
Each of these options have their strong points and weak-points and each individual much choose the level of protection that they deem necessary as well as staying within whatever budget they have available for such an endeuvour, and all while understanding their own level of computer/technical expertise. Some of these options can be very technical and/or time consuming (usually only at the initial setup).
Many may wish for simple, free, easy Data Backup...For you, I'd recommend OS-Based.
Others may wish for simple & cheap: OS or Software-based Burn-to-Disc.
Others still may want Real-time (or close to it) and aren't so concerned with ease or cost...for you, I'd recommend HW-based options (RAID or Dedicated Backup Drives)
Some may want mobile access to their data and are less concerned about the sensitivity of their data in which case I'd recommend Online-based storage.
in order to store multimedia presentations you need backing storage there are a number of backing storage devices which are all parts of the hardware of a computer system when discussing backing storage the term access is used in this unit we will only look at backing storage which has random or direct access is when the the storage device can go to a piece of data straight awy wherever it is sold. please note copied from a book

Define backing storage devices and describe any two of them

there is no difference!
Main memory in a computer is storage that will be erased when a computer is turned off. Backing storage is memory that will save information when the computer shuts down.
i am not sure
yes
Floppy drive and hard drive are two types of backing storage devices.
its computer memory
Storage which stores a copy of every file on the computer. Storage which stores every file copy in a computer.
