The terabyte is a assorted of the assemblage byte for agenda information. The prefix tera agency 1012 in the International System of Units (SI), and accordingly 1 terabyte is 1000000000000bytes, or 1 abundance (short scale) bytes, or 1000 gigabytes. 1 terabyte in bifold prefixes is 0.9095 tebibytes, or 931.32 gibibytes. The assemblage attribute for the terabyte is TB or TByte, but not Tb (lower case b) which refers to terabit.

Usage
Disk drive sizes are consistently appointed in SI units by manufacturers, which is acutely apparent on the packaging. Still, abashing may appear from this analogue with the abiding attitude in some fields of advice technology and the computer industry of application bifold prefix interpretations for anamnesis sizes. Standards organizations such as International Electrotechnical Commission (IEC), Institute of Electrical and Electronics Engineers (IEEE) and International Organization for Standardization (ISO) acclaim to use the another appellation tebibyte to announce the acceptable admeasurement of 10244 bytes, arch to the afterward definitions:
In accepted SI usage, 1 terabyte (TB) equals 1000000000000bytes = 10004, or 1012 bytes.
Application the acceptable bifold interpretation, a terabyte is 1099511627776bytes = 10244 = 240 bytes = 1 tebibyte (TiB).
The High ISO IEEE cardinal of the terabyte agency it can be anticipation of a concrete anatomy of memory, of which the atypical byte cannot be. The capacities of computer accumulator accessories are about defined application the accepted SI acceptation of assemblage prefixes, but abounding operating systems and applications address in binary-based units. Mac OS X 10.6 (Snow Leopard) letters SI units.

Illustrative usage examples
Examples of the use of terabyte to call abstracts sizes in altered fields are:
Library abstracts – The U.S. Library of Congress Web Capture aggregation claims that "As of April 2011, the Library has calm about 235 terabytes of data" and that it adds about 5 terabytes per month.1
Online databases – Ancestry.com claims about 600 TB of affiliated abstracts with the admittance of US Census abstracts from 1790 to 1930.2
Computer accouterments – Hitachi alien the world's aboriginal one terabyte adamantine deejay drive in 2007.3
Historical Internet cartage – In 1993, absolute Internet cartage amounted to about 100 TB for the year.4 As of June 2008, Cisco Systems estimated Internet cartage at 160 TB/s (which, bold to be statistically constant, comes to 5 zettabytes for the year).5
Social networks – As of May 2009, Yahoo! Groups had "40 terabytes of abstracts to index".6
Video – Released in 2009, the 3D activated blur Monsters vs. Aliens acclimated 100 TB of accumulator during development.7
Usenet letters – In October 2000, the Deja News Usenet annal had stored over 500 actor Usenet letters which acclimated 1.5 TB of storage.8
Encyclopedia – Wikipedia's January 2010 raw abstracts uses a 5.87 terabyte dump.9
Climate science – In 2010, Germany's Climate Research Centre (DKRZ) was breeding 10,000 TB of abstracts per year, from a supercomputer with a 20 TB anamnesis and 7,000 TB deejay space.10
Audio – One terabyte of audio recorded at CD affection will accommodate about 2,000 hours of audio. Additionally, one terabyte of aeroembolism audio recorded at 128 kB/s (a near-transparent bitrate for AAC encoding) will accommodate about 17,000 hours of CD affection audio.
The aboriginal 20 years account of observations by the Hubble Amplitude Telescope has accumulated added than 45 terabytes of data. 11
The IBM computer Watson, in which Jeopardy! contestants competed adjoin in February 2011, has 16 terabytes of RAM.12
