                  A computer converts the input into  meaningful information
                  through the processing device. The CPU (Central Processing
                  Unit) is a processor. It is the brain of a computer that does all
                  the calculations, runs all the programs and manages all the
                  operations. The CPU is a chip that is placed inside the CPU
                                                                                                   CPU     CPU box/

                  Output Devices

                  A computer displays the result of the processed data through the output devices.
                  Some of the output devices are monitor, printer, speakers, etc.

                  Monitor

                  A  monitor,  also called  the  Visual  Display  Unit  (VDU).  It
                  displays the output as softcopy (on its screen).

                                            A printer prints the output on a paper which is called a hard
                                            copy.
