B. ASCII
C. ISCII
D. EBCDIC
E. Extended ASCII
Choose the correct answer from the options given below:
Character Standards Ordering
To determine the correct chronological order, we need to consider the approximate development and standardization timelines for each character representation standard mentioned:
- D. EBCDIC (Extended Binary Coded Decimal Interchange Code): Developed by IBM in the 1960s for mainframe systems.
- B. ASCII (American Standard Code for Information Interchange): Developed in the early 1960s and standardized in 1968. It uses 7 bits.
- E. Extended ASCII: Developed later, in the late 1970s / early 1980s, expanding the original ASCII set using 8 bits to include more characters.
- C. ISCI (Information Systems Code): This standard is less universally defined than others, but generally refers to character sets used in information systems. Considering its position relative to others and the typical progression, it emerged after basic ASCII and Extended ASCII but before the global unification of Unicode. Development began in the 1980s.
- A. Unicode: Development started in the late 1980s, with the first version released in 1991. It aims to represent characters from all writing systems.
Correct Chronological Order
Arranging these standards based on their introduction dates gives us the following sequence:
- EBCDIC (1960s)
- ASCII (1968)
- Extended ASCII (late 1970s/early 1980s)
- ISCI (1980s)
- Unicode (1991)
Therefore, the correct sequence is D, B, E, C, A.
