Bit or a Byte
How Big is a Gigabyte?
Bit: A Bit is the smallest unit of data that a computer uses. It can be used to represent two states of information, such as Yes - No or 0 - 1.
.
Byte: A Byte is equal to 8 Bits. 1 Byte could be equal to one character. 10 Bytes could be equal to a word. 100 Bytes would equal an average sentence.
.
Kilobyte (KB) = approximately 1,000 bytes
A kilobyte (KB) is normally defined as 1,000 bytes. Technically, a kilobyte is actually 1,024 bytes which is 2 to the 10th power (1,024) bytes.
.
kilobit = approximately 1,000 bits
A kilobit is different than a Kilobyte.  A kilobit is approximately 1000 bits while a Kilobyte is approximately 1000 bytes.
.
Megabyte (MB) = approximately 1,000 KB or 1,000,000 bytes
Technically a Megabyte is 2 to the 20th power (1,048,576) bytes.
.
megabit = approximately 1,000 kilobits = 1,000,000 bits
.
In data communications, a kilobit is a thousand bits (or 1,000 bits) and a megabit is a thousand kilobits (or 1,000,000 bits).  These are normally used for measuring the amount of data that is transferred in a second between two telecommunication points. Kilobits per second is usually shortened to kbps and megabit per second is abbreviated as mbps.

Bits in data communications are discrete signal pulses.  For example, 28.8 kilobits per second (kbps) is 28,800 bits per second.
.
Gigabyte = approximately 1000 Megabytes = 1,000,000 Kilobytes = Billion bytes (1,000,000,000 bytes)
Technically a Gigabyte is 2 to the 30th power (1,073,741,824) bytes.
.
Terabyte (TB) = approximately 1,000 Gigabytes = 1,000,000 Megabytes = Trillion bytes (1,000,000,000,000 bytes)
Technically a Terabyte is 2 to the 40th power (1,099,511,627,776) bytes
.
Petabyte (PB) = approximately 1,000 Terabytes =  1,000,000,000,000,000 bytes
Technically a Petabyte is 2 to the 50th power (1,125,899,906,842,624) bytes
.
Exabyte (EB) = approximately 1,000 Petabytes = 1,000,000,000,000,000,000 bytes
Technically an Exabyte is 2 to the 60th power (1,152,921,504,606,846,976) bytes
.
It is estimated that if you were to type up every word ever spoken by every human being ever to live in all of the history of the world, the resulting file would be between 2 and 5 Exabytes in size.
.
Zettabyte  = 1000 Exabytes
.
Yottabyte  = 1000 Zettabytes
.
Brontobyte  = 1000 Yottabytes = 1,000,000,000,000,000,000,000,000,000 bytes = 1 followed by 27 zeros…

How big is 1 followed by 27 zeros?  That would be the rough equivalent of the total number of atoms contained in all of the bodies of every person living in Indiana… give or take a few billion-trillion here and there…
