Bitty Bits and Exact Exabytes
A byte is eight bits. An Exabyte is a billion gigabtyes.
A bit short for binary digit. A single binary value of either 0 or 1, a bit, is the smallest unit of data in a computer system.
One terabyte is a trillion bytes, which is the equivalent to the textual content of a million books. So many more millions of books on Amazon in Kindle such as The Webinar Way.
How many gigabytes are in a TB or MB?
