Terabyte
Terabyte definition
A "terabyte" (tB) is 1,000,000,000,000 bytes, or sometimes 1,099,511,627,776 even though the latter is known as a "tebibyte" (TiB or TB), as the "tera" technically means "trillion". The "TB", "TiB" and "tB" are also sometimes confused, as is "terabit" (tb or Tb) which is a trillion bits - one eighth of a terabyte. A terabyte is 1,000 gigabytes, whereas a tebibyte is 1,024 gibibytes.
