The terabyte is a multiple of the unit byte for digital information. The prefix tera represents the fourth power of 1000, and means 1012 in the SI units, and therefore one terabyte is one trillion.
1 TB = 1000000000000 bytes = 1012 bytes = 1000 gigabytes.
Terabytes are most often used to measure the storage capacity of large storage devices.
While hard drives were measured in gigabytes for many years, around 2007, consumer hard drives reached a capacity of one terabyte. Now, all hard drives that have a capacity of 1,000 GB or more are measured in terabytes. For example, a typical internal HDD may hold 2 TB of data.
