| BCD code its the onl. |
EBCDIC: The major problem with BCD code its the only 64 (2.6) Different character can represented in it this is not sufficient for providing, decimal number 10, lower case letters (260, capital letters 26, capital letters 26 and a large number of other special characters (24+). Hence the BCD. code was extended from it 6.bit code to an 8.bit code. the added 2 bit, are used as additional for zone bits, expanding the zone to 4 bits. the resulting code is called the extended binary at coded Decimal interchange code (EBCDIC). in this code. it is possible to represent 256 (2.8) different character. instead of 64 (2.6), in addition to various character requirements mentioned above, is also allows a large variety of printable character and several nonprintable control characters, the control characters are used to control such it activities as printer vertical spacing movement of cursor as for the terminal screen etc all of 256 bit. Combinations (have not). yet been assigned characters. hence the code cant it grow, as new requirements develop.
