1 Terabyte (TB) is equal to:

This question tests knowledge of standard computer storage unit conversions. In computing, storage units are typically based on powers of 2, specifically 1024, rather than 1000, due to the binary nature of computers.

The correct answer is 1024 GB. This is because computer memory and storage capacities are measured using binary prefixes, where each successive unit is 1024 (which is 2¹⁰) times larger than the previous one. The hierarchy is as follows: 1 Kilobyte (KB) = 1024 Bytes, 1 Megabyte (MB) = 1024 KB, 1 Gigabyte (GB) = 1024 MB, and therefore, 1 Terabyte (TB) = 1024 GB. This standard ensures precise measurement in a binary system.

• 1024 MB is incorrect because 1024 MB is equivalent to 1 GB, not 1 TB.
• 1000 GB is incorrect. While 1000 GB is often used in marketing for hard drive capacities (decimal prefixes), the precise binary standard in computing for a Terabyte is 1024 GB.
• 1024 KB is incorrect because 1024 KB is equivalent to 1 MB, which is significantly smaller than a Terabyte.
