One Terabyte is approximately equal to

Correct option is D

​A Terabyte (TB) is a unit of digital storage that is approximately equal to 1,000 gigabytes (GB) in the decimal (base-10) system, which is commonly used in storage devices.

• 1 Terabyte (TB) = 1,000 Gigabytes (GB)
• Alternatively, in binary (base-2) system used by computers:
  1 TB = 1,024 GB (technically accurate in some computing contexts).

Important Key Points:

1. Storage Hierarchy:
• 1 Kilobyte (KB) = 1,000 Bytes
• 1 Megabyte (MB) = 1,000 Kilobytes (KB)
• 1 Gigabyte (GB) = 1,000 Megabytes (MB)
• 1 Terabyte (TB) = 1,000 Gigabytes (GB)
2. Practical Use of 1 TB:
• 1 TB is commonly used to measure the capacity of external hard drives, SSDs, and cloud storage.

Knowledge Booster:

1. 1,000 Kilobytes
• Incorrect: 1,000 KB is equal to 1 Megabyte (MB), not 1 Terabyte.
2. Option B: 1,000 Bytes
• Incorrect: 1,000 Bytes is just 1 Kilobyte (KB).
3. Option C: 1,000 Megabytes
• Incorrect: 1,000 MB is equal to 1 Gigabyte (GB), not 1 Terabyte.
