                          Aryan: It is so much fun to work with computers. I was explaining it to my
                          mother that how it is so useful. Then my mother asked me a question, “Is our
                          fully automatic washing machine a computer?”

                                            Gowri: I wouldn't call it a computer. A computer is general
                                          purpose whereas a dedicated  embedded  system such  as a
                                          washing machine or microwave usually contains a microcontroller
                                          not a microprocessor. But before we go there, let me tell you
                                          basic components of computer.

                     2.1 BASIC COMPONENTS OF COMPUTER
                     Every Computer has four basic Components:

                          Input Device
                     Ø
                          CPU
                     Ø
                          Output Device
                     Ø
                          Memory Unit
                     Ø
                     Input Device: These  components  are  used to  give input to  the  computer  like
                     keyboard, mouse etc.

                                                                                  Computer Basics                       23
