Answer
Correct Answer: 2, 1, 4, 3
Explanation
Introduction / Context:SI prefix ordering checks understanding of powers of 10. You must place prefixes from the smallest factor to the largest.
Given Data / Assumptions:
- Kilo = 10^3 (2)
- Mega = 10^6 (1)
- Giga = 10^9 (4)
- Tera = 10^12 (3)
Concept / Approach:Compare exponents: 3 < 6 < 9 < 12.
Step-by-Step Solution:
Ascending: kilo (2) → mega (1) → giga (4) → tera (3).Verification / Alternative check:Write example scales: 1 kB < 1 MB < 1 GB < 1 TB.
Why Other Options Are Wrong:They disrupt the exponent order.
Common Pitfalls:Mixing up mega and giga; misplacing kilo.
Final Answer:2, 1, 4, 3
