A terabyte comprises of:

The correct answer is 1024 Gigabyte.

Key Points

• A terabyte (TB) is equal to 1024 gigabytes (GB).
• The prefix "tera-" in the International System of Units (SI) denotes a factor of 10¹² or 1 trillion.
• In the context of computer storage, however, a terabyte is often used to represent 2⁴⁰ bytes, or 1,099,511,627,776 bytes.
• This discrepancy arises because computers use binary (base-2) arithmetic, which aligns more naturally with powers of 2 rather than powers of 10.
• 1 TB = 1024 GB = 1,048,576 MB = 1,073,741,824 KB.

Additional Information

• Byte:
  • A byte is a unit of digital information that most commonly consists of eight bits.
  • It is the basic addressable element in many computer architectures.
• Gigabyte (GB):
  • A gigabyte is a multiple of the unit byte for digital information.
  • In the binary system, 1 GB = 1024 MB (megabytes).
• Kilobyte (KB):
  • A kilobyte is a unit of digital information equal to 1000 bytes in the decimal system.
  • In the binary system, 1 KB = 1024 bytes.
• Megabyte (MB):
  • A megabyte is a unit of digital information equal to 1,000,000 bytes in the decimal system.
  • In the binary system, 1 MB = 1024 KB.
