Detailed explanation-1: -1 terabyte (TB) equals 1, 000 gigabytes (GB) or 1, 000, 000 megabytes (MB).
Detailed explanation-2: -Peta-means 1, 000, 000, 000, 000, 000; a Petabyte is 1, 000 Terabytes. Exa-means 1, 000, 000, 000, 000, 000, 000; an Exabyte is 1, 000 Petabytes.
Detailed explanation-3: -One terabyte (TB) is about 1000 gigabytes, or roughly 1 trillion bytes. You can buy 4 TB hard drives today, so we are beginning the time when this term comes in to common use.
Detailed explanation-4: -In the case of 2TB, 2 terabytes (TB) equals 2, 000 gigabytes (GB) or 2, 000, 000 megabytes (MB).
Detailed explanation-5: -A gigabyte (GB)–pronounced with two hard Gs–is a unit of data storage capacity that is roughly equivalent to 1 billion bytes. In decimal notation (base 10), a gigabyte is exactly 1 billion bytes. In binary notation (base 2), a gigabyte is equal to 230 bytes, or 1, 073, 741, 824 bytes.
