              Storage Devices

              The devices that are used to store data are called storage devices. There are many storage
              devices to store our data or work, so that we can get it back whenever we need it. Let us

              discuss about some of the commonly used storage devices.

                                 CD and DVD

                                 The  CD  drive  reads  information  stored  on  a  Compact  Disc
                                 (CD). CD is an external storage device. DVD looks like a CD but
                                 can store much more data than a CD.


              Pen Drive

              Pen drive is a portable device and is easy to use. Its storage capacity is
              more than that of a DVD.

                                 The hard disk is permanently fixed in the system unit. It can store maximum
                                 data or work.
