3.2                  REPRESENTING INFORMATION


                                                                       AS BINARY CODES






                  Binary Representation

                  Look at the following symbols.











                  These  symbols  are universally  recognized  as  symbols  for  No  Parking  and  Keep

                  Silence respectively.

                  Similarly, computers use specific symbols to store and understand the information
                  that user has given to it as the input. This information is represented using Binary
                  numbers.






                      Binary Number is a number which represent data as 0s and 1s.



                  For example:

                      It can be used to record and use information                   0                           1
                       with the help of two signals: OFF(0) and ON(1).


                      Computers, phones, transistor are made up of the electronic parts that work on
                       the ON/OFF signals.

                  Let us learn how to make a smiley face using binary numbers.

                                                      0   1    0   0    0   1    0

                                                      0   0    1   1    1   0    0

                                                      0   0    0   0    0   0    0
