We use a cupboard to store books, toys,                We use a refrigerator to store
                  clothes, etc.                                          food, fruits, vegetables, milk, etc.


                     STORAGE DEVICES OF A COMPUTER

                 When we work on a computer, we can save our work for future use. For example,
                 when we draw something in Paint, we can save it on the computer and open it
                 later.  We store our work on a computer using storage devices.


                 Hard Disk

                 Hard disk is type of storage device which is fitted inside the CPU
                 box. It has the highest storage capacity.


                 CD and DVD                                                                            Hard disk

                 You must have seen these at your home or your
                 school. These are circular in shape and have a shiny
                 surface. You can store a lot of data in these.
                 A  CD and  a  DVD are  similar in shape  but,  the
                 storage capacity of a CD is lower than that of a
                 DVD. CD stands for Compact Disc and DVD stands
                                                                                          CD               DVD
                 for Digital Versatile Disc.


                 Pen Drive

                 A Pen drive is a small storage device. A pen drive has a higher
                 capacity than that of a CD or a DVD. It is so small that it can be
                 carried around in the pocket.

                                                                                                       Pen drive
                                    Memory Card

                                    A memory card is also a storage device that is much smaller than
                                    a pen drive. A memory card is used in a mobile phone, digital
                                    camera, or similar devices to increase their storage capacity.
