Question

The term ‘gigabyte’ refers to:

• A. \(1024 \text{ byte}\)
• B. \(1024 \text{ kilobyte} \)
• C. \(1024 \text{ megabyte} \)
• D. \(1024 \text{ gigabyte} \)

Hint:

Remember the order of magnitude for common data units: Byte - Kilobyte (KB) - Megabyte (MB) - Gigabyte (GB) - Terabyte (TB). In the context of computer memory and operating systems, each step is typically a factor of 1024 (\(2^{10}\)). Be aware that storage manufacturers sometimes use decimal prefixes (factor of 1000), but questions like this usually refer to the binary standard.

Answer 1

The Correct Option is C

Step 1: Recall the standard hierarchy of digital information units based on binary prefixes (powers of 1024, or \(2^{10}\)), commonly used in computing for memory and sometimes storage. \begin{itemize} \item 1 Kilobyte (KB) = 1024 Bytes \item 1 Megabyte (MB) = 1024 Kilobytes (KB) \item 1 Gigabyte (GB) = 1024 Megabytes (MB) \item 1 Terabyte (TB) = 1024 Gigabytes (GB) \end{itemize} Step 2: Based on this hierarchy, the term 'gigabyte' (GB) refers to 1024 megabytes (MB). Step 3: Comparing this definition with the given options, option (c) matches the correct relationship.
