What standard character encoding scheme uses 7 binary bits to represent 128 distinct characters, including English letters, numerals, and control codes?
Answer and explanation
Correct answer: C. ASCII
- Step 1: Early telecommunications and computing systems standardized character representations for interoperability.
- Step 2: The American Standard Code for Information Interchange (ASCII), established in 1963, allocated 7 bits () to encode lowercase and uppercase English letters, digits 0-9, and control characters like newline and carriage return.
Answer
ASCII
Why not the others: 'Unicode / UTF-8' UTF-8 is a variable-length encoding scheme using 1 to 4 bytes to represent over 140,000 global characters; 'EBCDIC' EBCDIC is an 8-bit character encoding system developed by IBM primarily for mainframe computers; 'Base64' Base64 is a binary-to-text encoding scheme that translates raw binary data into 64 ASCII characters for safe transport.
