Correct answer: D
Concept
Decimal SI prefixes scale in factors of 1,000: kilo = 103, mega = 106, giga = 109, and tera = 1012. Thus, each adjacent prefix level differs by a factor of 1,000. Binary prefixes such as KiB, MiB, GiB, and TiB instead scale in factors of 1,024.
Application
Write one terabyte in bytes: 1 TB = 1012 bytes.
Write one gigabyte in bytes: 1 GB = 109 bytes.
Divide the two scales: 1012 ÷ 109 = 103 = 1,000.
Contrast
Quantity | Decimal equivalent |
|---|---|
1,000 bytes | 1 kilobyte |
1,000 kilobytes | 1 megabyte |
1,000 megabytes | 1 gigabyte |
1,000 gigabytes | 1 terabyte |
Result
One terabyte is approximately equal to 1,000 gigabytes; under the decimal SI convention, the equality is exact.
