TERABYTE

As you might have guessed, this is a unit of measurement for computer data. A terabyte is 1000 gigabytes of data. And since a gigabyte is 1000 megabytes, and a megabyte is 1000 bytes, a terabyte is approximately one trillion bytes. If you want to be exact, a terabyte is 2^40, or 1,099,511,627,776 bytes. Either way, that's a lot of space. Though this term isn't used very much today, you'll probably be hearing it used more often in the future. That is, unless the computer industry starts to move backwards...
