A Terrabyte, TB means 1,000,000,000,000

A Gigabyte, GB means 1,000,000,000 Bytes

A Megabyte, MB means 1,000,000 Bytes.

A Kilobyte, KB means 1,000 Bytes.

A Byte is 8 bits.

Some spell Terrabyte as Terabyte.

Computers use a positive or negative state to control processes. Each state is stored as a 1 or a zero and is called a 'BIT.' It is used in a math called 'Binary Math.'

But a single bit is too small to be very useful. Programmers started putting the bits together in larger units. At first, they used 4 at a time, then 8, 16, 32, 64, 128, and 256. The term Byte was given to a group of 8 bits. The more bits are used, the more information they contain, and the more powerful the processors must be to handle it all. This can easily be seen when looking at the number of colors that can be displayed. 1 or zero is black and white. 16 bits are used for grays. 256 bits are used for simple gif image colors. More colors require more bits of information, and more memory to store the information.
