                 The result received after processing is called output. The devices which are used to
                 display the results are called output devices.

                           PARTS OF A COMPUTER


                 The computer system is made up of two parts—Hardware and

                 Software. Let’s learn about hardware and software in detail.



                           HARDWARE


                 The term ‘hardware’ refers to the parts of a computer that we can see and touch.

                 In other words, hardware are the tangible parts of a computer system.

                  The Hardware devices are classified into four categories:

                                                           HARDWARE




                   Input Devices          Processing Device           Output Devices           Storage Devices


                 INPUT DEVICES


                 The hardware devices that are used to give inputs in the form of words, pictures,
                 sounds, etc., to a computer are called input devices. Some of the most commonly
                 used input devices are:

                 Keyboard: A keyboard is an input device used to

                 give input  to  the computer  by  typing  numbers,
                 letters and special characters.                                              Keyboard
