    OUTPUT

                     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

                                             The invention of Qwerty keyboard

                                                                                                Hardware and Software  9
