                  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 our work. Some of the

                 storage devices are:

                 Hard Disk

                 Hard disk is fixed inside the CPU box. It can store the files that we
                 create on the computer and can be used later.
                                                                                                        Hard Disk
                                 Compact Disc (CD)

                                 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 storage
                                       device. The storage capacity of a pen drive is more than a DVD
                     Pen Drive         but less than a hard disk.

                     Storage devices act as both input and output devices.
