Name of the Items                               Number of the Items

                  1.  Shuttle Cock                                                         7

                  2.  Football                                                             5

                  3.  Chair                                                                4

                  4.  Table                                                                3

                  5.  Hockey Stick                                                         5

                 Now, let's sort the number of items in the above table in descending order. You
                 will get the following data:

                              Name of the Items                               Number of the Items

                  1.  Shuttle Cock                                                         7

                  2.  Football                                                             5

                  3.  Hockey Stick                                                         5

                  4.  Chair                                                                4


                  5.  Table                                                                3

                    DECODING

                 Data can also be represented in the form of a hidden/secret message, called as
                 coded data.  The hidden message can be in the form of a symbol, number, picture,

                 letter, or a pattern. The process of converting a hidden message to a meaningful
                 text is called decoding. Look at the code below used to solve the sums.

                 Code:

                  A = 1        B = 2        C = 3        D = 4         E = 5        F = 6        G = 7       H = 8

                 Sums:

                 1.   A  × B    =  B       2.   E  × A    =  E       3.    B  × C    =  F      4.    D  × B    =  H

                    Recap



                        Data refers to the raw input and processed data is known as information.
                        Information can be represented in the form of tables, pictures, maps, pictograms,
                         etc.

                        The process of converting  a hidden message to a meaningful text is called
                         decoding.
