A terabyte is equal to which of the following?

A terabyte is equal to which of the following?

• A. 1 thousand bytes.
• B. 1024 bytes.
• C. 1 million bytes.
• D. 1 trillion bytes.

Answer: (D)

A terabyte is a large unit of storage. In decimal form, it equals 1,000,000,000,000 bytes, which is one trillion bytes. That’s why the option describing one trillion bytes is the correct choice. To place it in context, smaller units go in this progression: a kilobyte is about a thousand bytes, a megabyte about a million bytes, and a gigabyte about a billion bytes. Some contexts use binary values, where 1 KiB = 1024 bytes, 1 MiB = 1,048,576 bytes, and 1 TiB = 1,099,511,627,776 bytes, but the terabyte commonly appears as 10^12 bytes in storage specifications, matching the one-trillion-bytes description.
