                     Note: • The ASCII code characters  between 0 to 31 are  unprintable control characters used to control hardware.
                          • 32 represents space which is included in printable characters.
                          • 33 to 126 are all printable characters.
                          • 127 represents delete which is a control character.

              ASCII representation of a word is given with an example:

              Example 1: Represent INDIA in binary code.
                                            ASCII code of  I  =  73
                                                        N  =  78
                                                        D  =  68
                                                         I  =  73
                                                        A  =  65

              Representing in binary notation 1001001 1001110 1000100 1001001 1000001.
              Advantages of ASCII code are as follows:

              •  It is universally accepted. Unicode coding which has now replaced ASCII coding is compatible with it.
              •  It has a character encoding system.
              •  The codes for letters and digits are well adapted to different programming languages.
              Disadvantage of ASCII code is as follows:

              •  It has a limited character set which can represent only the English language but is incapable of representing other
                languages of the world.
              To eliminate this drawback, ASCII 8 character encoding was introduced in 1980 which was an extended version of
                                       8
              ASCII 7. It could represent 2  or 256 characters (ranging from 0 to 255) which included letters used in other European
              countries like Latin, graphics, signs, etc.

              2.3.3 ISCII (Indian Script Code for Information Interchange)
              Introduced in the year 1991 by the Bureau of Indian standards, this encoding scheme was designed to represent the
              character set of different Indian languages. It follows a 8-bit encoding schema containing 256 characters. The first 128
              characters (0 to 127) are similar to the ASCII coding scheme.
