                             The computer system is made up of two types of parts—Hardware and Software.
                             A computer accepts data and instructions from you through input devices.
                              Processing is done on the data entered into the computer, to convert it into meaningful

                             information through a processor.
                              The three main components of CPU are: ALU, CU and MU.

                              The output devices are used to display the information and result of computation to
                             the user.
