What is the full form of EBCDIC?
- A.Extended Binary Control Decimal Interchange Code
- B.Enhanced Binary Control Data Interchange Code
- C.Extended Binary Coded Decimal Interchange Code
- D.Enhanced Binary Coded Data Integration Code
Correct answer
Explanation
The correct answer is C, Extended Binary Coded Decimal Interchange Code. EBCDIC is an 8-bit character encoding scheme developed by IBM in 1963 for its mainframe and midrange computers. Because it uses 8 bits for each character it can represent 256 different characters, twice as many as the 7-bit ASCII code, which handles 128. EBCDIC grew out of the older Binary Coded Decimal system and is still found on IBM mainframes, while ASCII became the standard for personal computers and Unicode now covers the scripts of the world, including Devanagari. A is wrong because the third word is Coded, not Control. B is wrong on two counts: the first word is Extended and the third is Coded. D is wrong because the expansion ends with Decimal Interchange Code, not Data Integration Code. Exam tip: EBCDIC is 8-bit and 256 characters, ASCII is 7-bit and 128 characters, Unicode is 16-bit and covers all scripts.
