A terabyte is pretty much the largest amount of computer space that is commercially available. It usually only comes in the form of an external hard drive. A terabyte is equal to 1024 gigabytes or 8,796,093,022,208 bits.
My mom ran out of room for our family photos and videos on our 500 gigabyte hard drive, so she had to buy a 1 terabyte hard drive... *headdesk*

Unit of disk space equal to 1000 Gigabytes. Something which you never actually get when you buy a hard drive advertised as having 1 Terabyte of disk space. Can be abbreviated to TB
My new 1 Terabyte hard drive is EMPTY but my computer says only 900GB is available. WTF?
