What is typically used to represent computer characters or words?

• A. ASCII code
• B. Unicode
• C. EBCDIC
• D. Binary

Answer: (A)

Charcter encoding is how computers map human characters to numbers so they can be stored and processed. ASCII code is the classic mapping that assigns a numeric value to each character, letting letters, digits, and punctuation be stored and transmitted as numbers. Its original 7-bit design covers 128 characters, and extended 8-bit forms add more symbols. Because ASCII is simple, widely supported, and interoperable across many systems, it’s the typical way we represent basic computer characters or words in everyday text handling. In modern contexts, Unicode serves the same purpose but on a much larger scale, capable of representing virtually every language. Many systems use Unicode (often via UTF-8), and its ASCII-compatible subset means ASCII text remains valid within Unicode. EBCDIC is an encoding used mainly on IBM mainframes, so it’s not the common choice for general computing. Binary is the raw sequence of bits underlying everything, but the meaningful mapping from bits to readable characters is provided by a character encoding like ASCII or Unicode, not by binary alone.
