                  i +  STORAGE DEVICES

                 Other than input devices, processing devices and output devices, a computer also
                 uses storage devices. The storage devices are used to store information and data.
                 Some of the storage devices are:

                 Hard Disk

                 Hard disk is fixed inside the CPU box/Cabinet. It can store the files
                 that we create on the computer and can be used later.

                                                                                                        Hard Disk

                                 This disc is circular in shape. It is a small storage device. The storage
                                 capacity of a CD is less than the hard disk.
                      CD
                 Digital Versatile Disc (DVD)

                 A DVD is similar to that of a CD in appearance. The storage capacity
                 of a DVD is more than a CD.                                                                DVD


                                       Pen Drive
                                       It is also known as USB Flash drive. It is a very small and portable

                                       storage device that can be carried in a pocket. The storage capacity
                     Pen Drive         of a pen drive is more than a DVD but less than a hard disk.
