FC0-U71 Tech Concepts and Terminology Practice Question
A technician is explaining data representation to a trainee. Which TWO of the following are character encoding standards used in computing? (Select TWO).
⚠ Common exam trap
The trap is mixing up file formats (MP3, JPEG, ZIP) with character encoding standards; candidates must recognize that only ASCII and Unicode/UTF-8 define how text characters are represented.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ASCII
ASCII (Option B) is a character encoding standard that maps 128 values (0–127) to English letters, digits, punctuation, and control codes, making it a foundational text-encoding scheme. Unicode/UTF-8 (Option E) is also a character encoding standard; Unicode assigns a unique code point to virtually every character in the world's writing systems, and UTF-8 is its variable-length (1–4 byte) encoding form used widely on the web. The other options are not character encodings: MP3 (A) is an audio compression format, JPEG (C) is an image compression standard, and ZIP (D) is a file archive/compression format, none of which define how characters are represented as numeric codes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
MP3
Why it's wrong here
MP3 is a lossy audio compression codec, not a character encoding standard; it defines how sound waveforms are compressed, not how characters map to bytes. It is tempting because it is a widely recognised data format, and would be relevant if the question asked about audio file formats rather than text representation standards such as ASCII or Unicode.
- ✓
ASCII
Why this is correct
ASCII assigns a unique 7-bit numeric value to each character, covering English letters, digits and control codes, which satisfies the stem's requirement for a character encoding standard. It maps characters to binary so systems can store and exchange text consistently, unlike image or compression formats.
- ✗
JPEG
Why it's wrong here
JPEG is an image compression standard, not a character encoding, so it cannot map characters to numeric values. It tempts because it is a widely recognised computing standard for representing visual data. JPEG would be the correct choice if the question asked about lossy photographic image formats rather than text encoding schemes.
- ✗
ZIP
Why it's wrong here
ZIP is a lossless archive and compression format for bundling files, not a character encoding standard. Character encoding defines how characters map to byte values, as ASCII and UTF-8 do. ZIP would be correct if the question asked about file compression or archiving formats instead.
- ✓
Unicode/UTF-8
Why this is correct
Unicode is a universal character set, and UTF-8 is its variable-width encoding using one to four bytes per code point. It satisfies the stem's requirement for a character encoding standard, covering virtually all world scripts.
