bigger than a terabyte? Please don't just say that 2 terabytes is bigger than one terabyte

Answer: A terabyte is equal to 1,024 gigabytes and there are lots of things bigger than one terabyte. Other useful terms are:

  • 1,024 Bytes = 1 Kilobyte
  • 1,024 Kilobytes = 1 Megabyte
  • 1,024 Megabytes = 1 Gigabyte
  • 1,024 Gigabytes = 1 Terabyte
  • 1,024 Terabytes = 1 Petabyte
  • 1,024 Petabytes = 1 Exabyte (In 2000, 3 exabytes of information was created.)
  • 1,024 Exabytes = 1 Zettabyte
  • 1,024 Zettabyte = 1 Zottabyte
  • 1,024 Zottabyte = 1 Brontobyte (That is a 1 followed by 27 zeroes.)

This is incorrect. The 1024-based system is for MEBABYTES and GIBABYTES. The 1000-based system is actually for MEGABYTES and GIGABYTES.
