Q. Explain Extended Binary Coded Decimal Interchange Code?
Extended Binary Coded Decimal Interchange Code (EBCDIC) is a character-encoding format employed by IBM mainframes. It is an 8-bit code and is NOT Compatible to ASCII. It had been designed mainly for ease of use of punched cards. This was mainly used on IBM mainframes and midrange systems like AS/400. Strength of EBCDIC was availability of wider range of control characters for ASCII. Character coding in this set is based on binary coded decimal which is, the contiguous characters in alphanumeric range are represented in blocks of 10 starting from 0000 binary to 1001 binary. Other characters fill in rest of range. There are 4 major blocks in EBCDIC code:
There are various different variants of EBCDIC. Most of these vary in punctuation coding. More details on EBCDIC codes can be attained from further reading and web pages on EBCDIC.
