Character encoding: The acronym ASCII expands to which standardized phrase used in computing for text representation?

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:

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.
