                 Now you know that a computer works on the IPO cycle. To follow this IPO cycle it uses

                 some devices. Let us learn about them in this chapter.


                      INPUT DEVICES


                 The devices that are used to give commands or instructions to the computer and tell
                 the computer what to do are called input devices. Let us study about some of them.


                 Keyboard

                 Keyboard is an input device that is used
                 to give instructions to the computer by

                 typing text and numbers. We type letters,
                 numbers and symbols using a keyboard.

                            Mouse


                            Mouse is an input device that sends instructions to the computer with the click
                            of a button. It is used to draw pictures and select objects on the computer.
