Character encoding: The acronym ASCII expands to which standardized phrase used in computing for text representation?
-
AAmerican standard code for information interchange
-
BAll purpose scientific code for information interchange
-
CAmerican security code for information interchange
-
DAmerican scientific code for information interchange
-
ENone of the above
Answer
Correct Answer: American standard code for information interchange
Explanation
Introduction / Context:ASCII is the historic 7-bit character encoding that maps letters, digits, punctuation, and control codes to numeric values. Correctly recalling its full form is a common exam objective.
Given Data / Assumptions:
- We are referring to the common computing acronym ASCII.
- Context is text representation.
Concept / Approach:
ASCII stands for American Standard Code for Information Interchange, defining 128 code points from 0 to 127 (including control characters like LF and carriage return).
Step-by-Step Solution:
1) Recall the standardized phrase.2) Select the option with exact wording and capitalization.Verification / Alternative check:
Examples: The character 'A' is 65, 'a' is 97, and space is 32 in ASCII. Many modern encodings (like UTF-8) remain ASCII-compatible for the first 128 values.
Why Other Options Are Wrong:
- 'Scientific' or 'security' variants are not the official standard name.
- None is incorrect because the correct expansion is present.
Common Pitfalls:
- Mixing 'standard' with 'scientific' or 'security' in memory.
Final Answer:
American standard code for information interchange.
