Speakers

                 Speakers produce music, speech or other sounds as output.



                                           Headphones

                                           Headphones are  small speakers used to hear  the sound
                                           without causing disturbance to others.




                 Projector


                 A projector displays the output from the computer screen
                 onto a larger screen.

                   Projectors are also used for Smartboards in schools.


                 Storage Devices

                 Storage devices are the hardware devices used to store data. Once you have finished
                 working with your data, you can store the data permanently in storage devices.

                 Some examples of storage devices are Hard disk, DVD and Pen drive.

                     SOFTWARE

                 Computer hardware cannot work by itself. It needs step-by-step instructions to
                 perform a task. These step-wise instructions are called software. The games you play

                 on a computer are examples of software. There are mainly two types of software:
                 system software and application software.
                 System Software

                 System software controls and manages the overall activity of a computer system.

                 So, the system software is like a manager of a computer system. Without system
                 software, the computer is like a car without a driver.
