                                              .             11            1011             73
                 The representations are shown below as examples:
                 Example 1: Represent JAVA as 6-bit BCD code.
                 The BCD binary notation of the characters are given below:

                                                           J   =  10  0001
                                                           A  =  11 0001
                                                           V  =  01 0101

                 Thus, the BCD equivalent is 100001 110001 010101 110001.
                 Example 2: Write the Octal notation in BCD coding for the word BAT.
                 The BCD Octal notation of the characters are given below:
                                                           B  =  62
                                                           A  =  61
                                                           T  =  23
                 Thus, the BCD octal equivalent is 62 61 23.
                 2.3.2 ASCII (American Standard Code for Information Interchange)
                 ASCII is the most popular coding scheme used as industry standard in computers and the web. It was introduced
                 in 1960. Originally, ASCII was designed as a 7-bit character set having 2  or 128 characters. It could represent all
                                                                                   7
                 digits from 0 to 9, upper case and lower case English alphabets and some special characters. The ASCII codes of 128
                 characters are listed in the table below:
