The major problem with BCD code is that only 64 (2 to the power 6) different charactor can be represented in it.
this is not sufficient for providing decimal numbers (10), lower case letters (26), and large number of other special characters (28+)

...And EBCDIC was obsoleted by ASCII because EBCDIC did not use continuous coding (all the letters of the alphabet in increasing binary values), and because IBM made it difficult for others to use.
Extended binary coded decimal interchange code
in EBCDIC: 11001000, 10000101, 10010011, 10010011 10010110 in ASCII: 1001000, 1100101, 1101100, 1101100, 1101111 in Unicode: 0000 0000 0100 1000, 0000 0000 0110 0101, 0000 0000 0110 1100, 0000 0000 0110 1100, 0000 0000 0110 1111
Many non-integral values, such as decimal 0.2, have an infinite place-value representation in binary (.001100110011...) but have a finite place-value in binary-coded decimal (0.0010)[bcd]. Consequently a system based on binary-coded decimal representations of decimal fractions avoids errors representing and calculating such values. Rounding at a decimal digit boundary is simpler in BCD. Addition and subtraction in decimal does not require rounding.
BCD is used for binary output on devices that only display decimal numbers.
That would depend on which computer character code you want to use, there have been thousands of them. The most current is Unicode an extension of ASCII. Unicode can support every living language on earth and many dead ones too. However it has multiple coding standards.Some other now largely considered obsolete computer character codes are EBCDIC (still used on come IBM mainframe computers), FIELDATA, BCDIC (used by IBM before they developed EBCDIC in 1964), CDC Display Code, Hollerith punch card code, BAUDOT, etc. Some computers (e.g. IBM 1401, IBM 650, IBM 1620) actually used different character codes in their internal memory than they used for input/output.Computer character codes before the 1960s generally were limited to capital letters only (these were typically 6 bit codes, not the 8 bit that IBM introduced with EBCDIC in 1964 on their System 360 or the new 7 bit standard teletype code ASCII introduced just before that and soon adopted by computer manufacturers other than IBM).In ASCII the word Tina is the following Hexadecimal bytes (you can convert to binary):T = 54Hi = 69Hn = 6EHa = 61Hin EBCDIC the word Tina is the following Hexadecimal bytes (you can convert to binary):T = E3Hi = 89Hn = 95Ha = 81H

EBCIDIC (Extended BCD Interchange Code)Unicode
EBCDIC is Extended Binary Coded Decimal Interchange Code. It was the character encoding scheme developed and used by IBM. EBCDIC is completely overshadowed by ASCII and ASCII's big brother, Unicode. EBCDIC is very difficult to use, as the alphabet is non-contiguous and the encoding makes no logical sense.
The Extended Binary Coded Decimal Interchange Code (EBCDIC)
The acronym EBCDIC means: Extended Binary Coded Decimal Interchange Code. The EBCDIC is an 8-bit character encoding system used on IBM systems that stems from the old punch card systems used in the 1950's and early 1960's.
One advantage of EBCDIC (Extended Binary Coded Decimal Interchange Code) is that it supports a wider range of characters compared to ASCII, including special characters used in IBM mainframe systems. EBCDIC is often still used in legacy systems and environments where compatibility with older technologies is important.
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc

EBCDIC (Extended Binary-Coded Decimal Interchange Code) is a character encoding system used by IBM mainframe computers. It is a binary code used to represent character data, and is an extension of the earlier ASCII code. EBCDIC is used primarily on IBM mainframe computers, and its variants are used on IBM midrange computers. EBCDIC has a number of advantages over ASCII. First, it is a more efficient code, requiring fewer bits to represent a character. Second, it allows for more characters to be represented, including accented characters and non-Latin alphabets. Third, it has built-in error-checking features that ASCII does not have. However, EBCDIC also has a number of disadvantages. First, it is not as widely used as ASCII, so there is less software available that can work with it. Second, it is not as easy to convert data from EBCDIC to ASCII (or vice versa) as it is with ASCII. Finally, EBCDIC is a proprietary code, developed and owned by IBM, so it cannot be used by other computer manufacturers without a license from IBM.
