Acronym expansion: “ASCII stands for American Standard Code for Information Interchange.” Confirm whether this expansion is correct.

Introduction / Context:Acronyms are pervasive in computing, and expanding them correctly is essential for clear communication. ASCII is one of the most historical and influential encodings for text in computers and telecommunications. The question checks recall of the exact expansion of ASCII.

Given Data / Assumptions:

• ASCII defines a mapping from numerical codes to characters and control symbols.
• Original ASCII is a 7-bit code (0–127), with many 8-bit extensions historically used.
• Unicode and UTF encodings supersede ASCII for multilingual text, but ASCII remains a subset and a baseline.

Concept / Approach:Confirm the words behind each letter: A = American, S = Standard, C = Code, I = Information, I = Interchange. This exact phrase is canonical in standards documentation and textbooks.

Step-by-Step Solution:

Verification / Alternative check:Standards references and technical glossaries consistently give “American Standard Code for Information Interchange.” It appears in documentation for serial communications, file formats, and programming language references.

Why Other Options Are Wrong:

• Incorrect expansions replace “Code” with “Character” or “Communication,” or change “Information Interchange” to other phrases; these do not match the standard.

Common Pitfalls:Swapping “Code” and “Character,” or using “International” instead of “Information”; these are common memory slips but are not accurate for ASCII.

Final Answer:Correct
