Digital Versatile Disc (DVD)


                  A DVD looks similar to a CD. It is used to store a huge
                  amount of data. The storage capacity of a DVD is more
                  than a CD but less than a hard disk.

                                       It is a small storage device, also known as the USB Flash drive. It
                                       is used to transfer data from one computer to another. It can be

                    Storage devices act as both input and output devices.









                          The parts of a computer are divided into three categories—input devices,

                        output devices and storage devices.
                          Input devices are used to instruct the computer what to do.

                          Keyboard, mouse, scanner and microphone are some of the input devices.
                          Output devices are used to give the result.

                          Monitor, printer, speakers, headphones and headset are some of the output
                        devices.

                          Storage devices are used to store our work.

                          Hard disk, CD, DVD and pen drive are some of the storage devices.
